    15 20 25 30 amount. This creates imbalances in the groundwater balance, with the risk of, for example, salt water penetration and drainage of water wells. In addition, frequent sludge suction is required, which is costly.
    Furthermore, it is often not advisable or permissible to use fresh water from watercourses or the sea for, for example, flushing a water toilet that is connected to an infiltration plant, as this can add unacceptably large amounts of nutrients and bacteria to the local environment at the property.
    Furthermore, from the perspective of society, it is often desirable to collect the nutrient- and energy-bearing parts. of the wastewater, such as biological material and nutrients, for return to the larger cycle. A conventional treatment step, such as a so-called mini treatment plant, often removes a certain part of this desirable material by, for example, oxidation of carbonaceous material, collecting certain chemicals such as phosphorus in filters and the like which must later be deposited, and so on. .
    This means that these substances cannot be utilized optimally in the larger cycle.
    The dry substance in wastewater from water toilets constitutes a valuable raw material for the production of, for example, biogas. As such, however, specific requirements are placed on, among other things, the degree of chemical contamination and the degree of dryness of the sewage sludge.
    In addition, a conventional treatment step of the above-mentioned type is often, extremely expensive, connected directly to the sewer line, which means that operational faults cause immediate cessation of the treatment function, which either leads to waste water-producing equipment, such as a water toilet or a dishwasher, not being used. j_ waiting. on service technicians, Application text docx 2012-0I-04 | 1005155 10 15 20 25 30 or, which is worse, that the waste water from such equipment flows straight through the failed purification stage and into nature without the user receiving immediate information about this. In addition, such a purification step typically also consumes environmentally harmful chemicals, which must be disposed of or released into nature.
    Many conventional sewage management systems for use in properties without municipal sewers also set specific requirements for the type of wastewater-producing equipment that can be used in properties, such as requirements. low-flush water toilets. This not only infringes on the user's freedom, but also means that such systems are associated with increased installation costs.
    The Swedish patent with number 531290 describes a procedure for maintaining the water balance in a property, where wastewater is removed and fresh water, for local storage, is returned in a corresponding amount. This procedure requires, in addition to frequent sludge suction, regular external refilling of fresh water.
    The Swedish patent application not yet published at the time of the present invention with number 1100791-1 describes a method and a device for handling and purifying waste water from one or more water toilets, whereby the waste water is allowed to evaporate and condensation water is collected in a separate vessel. for use as rinsing water.
    Finally, for reasons of convenience, there is a need for portable toilet facilities, including water toilets, in places that do not have a municipal sewer or other permanent way of disposing of waste water from a toilet. This applies, for example, to festivals and other temporary events- Application application document 2012-01-04 | | 005 | SE 10 15 20 25 30 mang, on construction sites, disaster sites and j. Developing countries.
    In conclusion, it is desirable to provide a method for managing wastewater from one or more water toilets which only minimally affects the local water cycle and is reliable, which requires a minimum of maintenance and sludge suction, which can collect the entire energy and nutrient-containing fraction and which is possible both to install and to operate.
    The present invention solves the problems described above.
    Thus, the invention relates to a method of purifying wastewater from a first water toilet, comprising the steps of a) transferring the waste water from the first toilet to a locally arranged waste water collection container; b) allowing the waste water in the collection container to evaporate and condense again on a condensing surface; c) collecting the water thus condensed in a locally arranged storage container for condensed water; d) use the condensed water for flushing in a second water toilet, which may be the same as the first water toilet; and e) removing from the collection container the sludge which remains in the collection container after further evaporation for further treatment; whereby when the amount of water in the storage container exceeds a certain maximum amount, return the excess amount of water to the collection container.
    The invention also relates to a combination container associated with an upright operating orientation, comprising a collection container for wastewater, arranged to receive and accommodate a certain maximum amount of wastewater, and a storage container for condensed water, arranged to receive Application text document 2012-01-04 110051515 10 15 20 25 30 and housing a certain maximum amount of condensed water, characterized in that the combination container further comprises a condensing surface on which. water, son: evaporated from. the collecting container, can condense, by the combination container, when oriented in the operating orientation, being arranged to direct the water condensed on the condensing surface to the storage container by means of gravity, and, when the amount of water j. the storage container exceeds the certain maximum amount of condensed water, return the excess to the collection container by spreading from the storage container.
    The invention will now be described in detail, with reference to exemplary embodiments of the invention and the accompanying drawings, in which: Figure 1 is a schematic diagram illustrating an exemplary embodiment of the present invention.

    Figures 3a-3c show the basic structure of a second exemplary combination container according to the invention. Figure "3b shows the container in figure 3a in cross section.
    Figure 3c is a detail view of a part of figure 3b.
    Figures 2a and 2b, and 3a, 3b and 30, respectively, share reference numerals for corresponding parts. Figures 2a-3c are partially exploded and simplified schematic diagrams.
    Figure 1 shows a house 110 on the land 115, in the form of a detached house or an apartment building. In the house llO there is a toilet lll fixed and permanently installed. It is understood that the house 110 may have more than one toilet lll permanently and permanently installed, Application text docx 2012-01-04 | 1005155 10 15 20 25 30 to which other toilets what is stated herein is applicable in a corresponding manner. The toilet 111 is a water toilet, which is flushed with water. Preferably, the toilet 111 is not of so-called ultra-low flushing, i.e. toilet type, flush volume is preferably at least 2 liters. Above all, it is preferred that the same toilet 111 as previously used in the property, also continues to be used as part of a facility according to the present invention after the facility in question has been installed. This means, for example, that the sealing layer in the wet room in which the toilet 111 is located does not have to be broken.
    The wastewater is led from the toilet 111, 124, via a sewer pipe to a local, ie. on the same property as, and preferably in the immediate vicinity of, the room in which the toilet 111 is installed, arranged collection container 121 for wastewater. The collection container 121 preferably forms part of a combined container 120 for wastewater and condensed water, see below.
    It is preferred that the wastewater is not passed on from the collection container 121 in any way, except that the water fraction is partially removed, as described below.
    In addition, it is preferred that the remaining fraction, in other words the sludge remaining in the collection container 121, be emptied from time to time, when necessary when the volume of waste water becomes too large or its dry content becomes too high, and / or at regular intervals. preferably by conventional sludge suction, for example by removing a lid 122 covering the container 121 so as to allow access to the container 121, and removing it from the collection container 121 for further treatment. Such further treatment consists, for example, of digestion into biogas, and is preferably carried out at a central plant. Thus, after the evaporation of water described below, the entire residue in the collection container 121, after the evaporation of water described below, is removed from the container 121 for central handling.
    The collection container 121 is arranged to store the waste water as a waste water volume 128 with an open surface 130. the contained water that 120 Thus, the waste water will continuously continue to the atmosphere arranged in the container. The evaporated water is recondensed on one which preferably comprises an inside of the container 120, condensing surface, i.e. including on an inside of the lid 122. In addition, of course, other surfaces which are in contact with the atmosphere above the liquid surface 130 are included, such as the upper portions of the inner side surfaces of the container 120 as illustrated in Figure 1.
    From this condensing surface, the condensed, liquid water is then collected, and transferred to a storage container 123 for condensed water. The storage container 123 thus contains a volume of condensed water 129, which part may also comprise a proportion of fresh water which is not supplied therefrom after it has been carried by condensation, see below. condensed the water, via a line 125 and a pump 112, to a second water toilet, which may be the same as the first water toilet 111, and used there for flushing in said second toilet. The pump 112 can also be arranged in other places between the container 123 and the toilet, the container 123. as submerged in It is also noted that in the figures the first and the second water toilet are both shown as the toilet 111, but it will be appreciated that a number of water toilets e.g. can share the same treatment plant according to the present invention, and thus use the same collection container 121, etc. It is preferred that the storage container 123 constitutes the only source of flushing water for the second water toilet- Application text Ldocx 20l 2-0 I -04 1 | 005 | SE 10 15 20 25 30 ten, preferably for all water toilets that are installed in the same house 110 and preferably on the same property.
    It is thus the sludge which after said evaporation remains in the collecting container 121 which is removed from the collecting container 121 for further treatment.
    In order to increase the evaporation rate, it is preferable to have a device for supplying external heat energy, in order to be able to supply such energy to the collection container 121. If necessary. A preferred way of supplying such energy is by means of an electric immersion heater 117. however, it will be appreciated that other means, such as a closed heat carrier circuit, where the heat carrier is heated by means of a heat exchanger connected to an external energy source (not shown), or directly by means of solar heat, may be used. It is preferred that the said energy supply device is arranged to be switched on only in connection with an increased need for flushing water, such as when more people than those who normally live on the property in question are planned to be on the property for a limited period of time. . It has been found that an externally supplied energy of as little as or equal to 1000 W, more preferably equal to or less than 500 W, more preferably equal to or less than 200 W, preferably equal to or less than 100 W, is sufficient to sufficiently increase the evaporation rate to be able to cover temporary peaks in 121, in case of flushing water demand. It is preferred that the container, or at least the container 120, be heat insulated in the heat 130, external heat energy can be supplied. It is preferred that the meenergy is applied at or adjacent to the surface, for example genius that the heating step 117 is in shape. of a liquid heating coil, such as an electric resistance heater arranged to float on the surface 130, such as a heating cable arranged inside a water-filled tube of liquid plastic material.
    Application text document 2012-OI-04 1 1005 | 55 10 15 20 25 30 This entails, among other things, reduced heat losses to the container 123.
    When the amount of water in the condensed water storage container 123 exceeds a certain predetermined maximum amount, according to the invention, the excess amount is returned to the waste water collection container 121.
    Thus, all contents of the containers 121, 123 will originate from the water toilet 111 and any other water toilets on the property. Since the flushing water in the toilet III consists entirely of evaporated and recondensed water, apart from any initially supplied amount of fresh water (see below), no additional water is supplied to the containers 121, 123 through the flushing water. Instead, only the material, in the form of urine, is supplied in addition to 123 feces and so on, the actual rinsing water to the containers 121. . Depending on the rate of evaporation in combination with the rate of return of condensed water, a certain amount of rinsing water can also be supplied to the container 121.
    Thus, after a continuous period of continuous operation, the dry matter content of the collection container 121 will generally be relatively low, and can also be controlled within a relatively narrow range. For example, the dry matter content can be kept at a level at least equivalent to that of wastewater, including rinsing water, originating from a so-called ultra-low-flushing water toilet, which uses significantly less than 2 liters of rinsing water per flush, so less than 1 liter per conventional purge flushing. plant otherwise must perform expensive evaporation of sewage sludge Application text docx 2012-01-04 110051515 10 15 20 25 30 lO before digestion. Thus, the water content of the dewatered latrine in the collection container 121 can be regulated to create optimal conditions for energy and / or nutrient recovery in a central treatment plant.
    At the same time, substantially all of the organic constituents will remain in the collection container 112, which is desirable prior to a later digestion or dehygienation step.
    The amount of sludge present in the collection container 121 at preferably the maximum sludge suction becomes even smaller; 50%, preferably a maximum of 30%, of the total amount of wastewater supplied from the water toilet, including the flushing water.
    This means that one and the same sludge suction truck can serve more properties than before, which leads to economic and environmental benefits.
    Since the flushing water consists of recycled black water from toilet lll, the local water balance is not charged, even though a standard conventional water toilet is used.
    The fact that no ultra-low-flush toilet needs to be installed means not only increased comfort of use, but also that existing waterproofing layers in the bathroom can be retained. and the fact that the latter, an existing standard water toilet can be retained in the installation of a system for carrying out a method according to the present invention, entails significant cost savings.
    The low number of required moving parts in the system also entails low operating costs and high availability.
    The system also does not cause any environmental impact in the form of emissions into the local environment, neither from water nor from residues from local treatment stages.
    It is preferred that the mouth 126 of the drain line 124 be arranged substantially in the middle of the surface 130, at a height above the bottom of the collecting container 121 which is only a few centimeters, such as a maximum of 10 cm, higher than the maximum wastewater depth. It is also preferred that the mouth 126 be arranged so that the waste water is supplied substantially vertically downwards from the mouth 126. This minimizes the amount of splashing when the waste water is supplied, which in turn increases the purity of the condensed water.
    It is further preferred that the condensed water on its way between the storage container 123 and the second water toilet passes an activated carbon filter 116, i.e. a filter through which the water is forced to flow activated carbon. through porous This removes foul-smelling constituents of the condensed water, as well as certain other contaminants, which, for example, means that the flushing water does not smell bad in the toilet.
    It is preferred that the storage container, 123 and the collection container 121 be designed as a single, continuous space.
    In Figure 1 this is the case, since the containers are connected to each other via a hole 131. The container 120 is arranged to lead water as condensed on the inside of the lid 122, by draining along the insides of the container 120, down to a gutter 127 which preferably runs around all the sides of the container 120, and which chute 127 also slopes down towards the place along the chute 127 where the hole 131 descends to the storage container. 123 is present In this way, all condensed water is led down to and along the gutter arranged. 127, up to the hole 131 and thereby down to the storage container 123.
    Application text document 2012-01-04 1 10051515 10 15 20 25 30 12 Since the containers 121, via the hole 131, 123 are only connected to each other, all condensed water will be fed to the storage container. while. the possibility of contamination from the collection container 121 to the storage container 123 is limited. It is further preferred that the container 120 be made of a material which. are substantially impermeable to sunlight, and preferably the container 120 is for the most part or, in this way, completely buried in the ground 115. more the space formed by the containers 123 to be dark, whereby the growth of bacteria, algae and so on furthermore can be limited to sufficiently low levels without the use of chemicals.
    According to a preferred embodiment, the above-mentioned return of condensed water from the storage container 123 back to the collection container 121 takes place by the contents of the storage container 123 widening over to the collection container 121, in the exemplary embodiment illustrated in Figure 1 via the hole 131. Such widening means that the return can be done in a reliable and automatic way, if necessary, without the need for any moving parts. It is noted that the maximum level of the waste water in the container 121 must be chosen to be lower than the height of the hole 131, since no liquid from the liquid body 128 can be allowed to flow directly from the body 128 down into the container 123.
    It is further preferred that an amount of fresh water corresponding to the maximum amount of water in the storage container 123 in an initial step is supplied to the storage container 123. In other words, the storage container 123 is full at the beginning of the operation. Thus, when wastewater is supplied to the collection container 121 and condensed water flows down to the hole 131, none of this water will end up in the storage container 123, which is already filled to the brim. On the other hand, when flushing water is carried to the toilet 111, space for additional condensate water is created, which then continuously fills the container 123 up to a point when it is again filled to the brim. In other words, during operation, the storage container 123 is continuously filled with condensed water up to the maximum amount of water in the storage container 123, after which further added condensed water causes the excess amount of water in the storage container 123 to be returned to the collection container 121.
    The solution illustrated in the figures, where gravity is used to carry water both from the container 121 to the ef-container 123 and vice versa, is particularly advantageous, since the container 120 can then be made passive, without moving parts.
    It will be appreciated, however, that instead of overflow from the container 123, it would also be possible, for example, to arrange excess water back from the container 123 to the container 121. by a separate pump or to carry Thus, an amount of water approximately corresponding to the initially supplied amount of fresh water the time in the container 123, and the contents of the collection container 121 will always, in terms of chemical composition and degree of dryness, substantially correspond to the material added in addition to the flushing water in the toilet 111, regardless of the total amount of wastewater in the container 121. This gives a fraction with very predictable properties in the container 121, which in turn gives good digestion and hygienic results.
    It is preferred that the first and second water toilets, the waste water collection container 121, the condensed water collection container 123, all of the pumps 112, pipes 124, 125, valves described herein. 340 and filter 116, the possible heating step 117, and so on, all constitute permanently installed parts of a fixed and permanently installed installation for the management of wastewater in a property which lacks municipal sewage.
    It is further preferred that only wastewater from one or more water toilets is fed to the collection container 121 for wastewater, and that no wastewater originating from other types of waste producing units is fed to said collection container 121. This provides good conditions for both energy and nutrient recovery.
    A control device 114 is further arranged to control the operation of the pump 112 and any other necessary moving parts, such as valves, and so on. In addition. are other pumps, and the control device 114 is arranged to energize and control the heating device 117 in a suitable manner.
    The purified water in the container 123 is thus used for flushing in the toilet 111, and is thus returned to the container 121 for purification, whereby a cycle is achieved. By using both the waste water collection container 121 and the purified water collection container 123, it is possible for the water toilet 111 to be made self-sufficient in flushing water, even though the flow from and to the water toilet 111 is intermittent side more or less continuously.
    Thus, it is achieved by such a procedure and such a device that a property that is not connected to municipal sewers can be equipped with one or more water toilets.
    Instead, it is sufficient that the much more limited amounts of sludge in the container 121 are emptied if necessary. Such emptying can take place at regular intervals, alternatively when the contents reach a certain minimum volume and at the same time maintain a desired degree of dryness.
    The volume of the container 121 can conveniently be monitored by means of a measuring equipment 113, for example in the form of a counter or a flow meter, son1 measures the number of flushes or the amount of flushed water in the toilet 111, and communicates this data to the control device 114. At the same time or alternatively the container 121 is measured by a measuring data placed therein, such as one which also communicates order level sensors, to the control device 114.
    Figures 2a-2b and 3a-3c, respectively, illustrate in principle two different embodiments of the container 120 illustrated in Figure 1, in the form of combination containers 200 and 300, respectively, comprising both respective collection containers 220, 320 for wastewater, arranged to receive and accommodate a certain maximum. amount of wastewater, and storage containers 230, 330 for condensed water, arranged to receive and accommodate a certain maximum amount of condensed water.
    A respective hole 231, 321 is arranged to pass through the drain pipe 124, 332 and a respective bottom hole 232 is arranged to connect the pipe 125. It will be appreciated that it is also possible to arrange the hole 232, the container 200, 332 in places other than in 300 bottoms.
    The combination containers 200, 300 are associated with a respective upright operating orientation, in which the combination containers are oriented as illustrated in the figures, with a respective lid 210, 310 upwards.
    The combination containers 200, 300 further comprise a respective condensing surface 213, 313, on which water, which is evaporated 312 from the collection container 220, 320 to a space 212, arranged above a free liquid surface in the container 220, 320 for wastewater, can condense.
    When the respective combination container 200, 300 is oriented in said operating orientation, the condenser 330 is according to the invention 313, arranged to direct the water to the storage container 213 to the condensing surface 230. When then the amount of water in the storage container 230, 330 exceeds the certain maximum amount of condensed water, the respective combination container 200, 300 is arranged to return the excess amount to the collection container 220, 320.
    As described above, it is preferred that the respective storage containers 230, 330 and the respective collection containers 220, 320 be designed as a single, continuous space.
    As also described above, it is preferred that the respective combination container 200, 300 be arranged to return the excess amount of water in the storage container 230, 330 back to the collection container 220, 320 by overflow from the storage container 230, 330.
    In the combination container 200 this is done by the container 220 being arranged as a free-standing container, arranged on legs 221 inside the container 230. A gap 225 of between 1-5 cm around the container 220 allows condensed water to flow along the condensing surface 213 and further, along the inner walls of the container 230, down into a space 233 in the container 230 located below the container 220. The spreading then takes place by the water level in the container 230 rising all the way up to the upper edge of the container 220 walls, after which spreading Application text document 2012-01-04 | 1005 | 5E 10 15 20 25 30 17 sker. Such a construction is simple and thus cheap to manufacture.
    In the combination container 300 the return takes place in that the container 330 is arranged below and in the extension of the container 320. An edge along the sides of the container 320 forms a gutter or surface 324, which partly slopes downwards outwards from a space 323 in the container 320 which is intended for collecting waste water, and slopes along the sides of the container 320 towards a place along the channel 324 where a hole 325 is provided, which hole 325 leads' downwards down to the container 330 and to a space 333 therein for condensed water . The chute 324 is thus arranged to catch and lead 313 to the hole 325. Spreading occurs when the water level in the container 330 reaches and condensation water from the condensing surface passes the level of the hole 325, possibly the edge of the chute 324. Such a construction, where the communication between the containers 320 and 330 is limited to one place, minimizes the contamination from the container 320 to the container 330 of the waste water. In addition, a suitable valve 340, such as a valve that closes tightly as long as a certain minimum pressure is not applied in either direction, is provided in the hole 325 to further reduce the risk of contamination. Valve 340 is best seen in Figure 3c. It is preferred that the communication between the containers 320 and 330, whether limited to one or more holes, is limited to a total cross-sectional area of a maximum of 100 cmz, preferably a maximum of 10 cmz, preferably a maximum of 1 cmz, preferably a maximum of 0 cmz. , 1 cmz.
    It is preferred, as is clear in Figures 2a-3c, that the condensing surface 213, 313 of the respective combination container 200, 300 comprise the inner surface of an externally upwardly convex roof, which in said operating orientation is arranged substantially vertically above the collecting container 220, 320. , Application text docx 2012-01-04 1 1005155 10 15 20 25 30 18 and also covering the collection container 220, 320. Along the roof, water as condensed on the surface 213, 313 can then run down along the sides of the roof and then be passed on to storage. container 230, 330 as described above. Since the roof is convex from the outside, it can be designed so that all or substantially all of the water that condenses on the condensing surface 213, 313 through drainage is led down to the storage container 230, 330 rather than back to the collection container 220, 320. by dripping. A preferred convex design is a curved, semicircular, shape. The mold may be curved in a horizontal dimension, as in the examples illustrated in Figures 2a-3c, or in two horizontal dimensions, such as a hemispherical shape.
    It is preferred that the respective lid 210, 310 be connected to either the storage container 230 or the collection container 320 by means of a connection 211 and 311, respectively, which is at least liquid-tight with respect to condensate running down along the lid 210. 310 inner surfaces and passes the connection 211, 311.
    As not illustrated in Figures 2a-3c, but in principle in Figure 1, the condensing surface may comprise a corrugated surface 133, for example in the form of a corrugated plastic insert arranged to divert condensation water, by drainage, towards 120 and down along with the inner walls of the container for further transport to the container 123. Such a corrugated surface 133 increases the total condensing surface, which improves the turnover rate in the container 120.
    As illustrated both in Figures 2a-2b and in Figures 3a-3c, the respective combination container 200, 300 preferably comprises a double-bottomed structure, with an outer bottom 234, 334 and an inner bottom 222, 322, where in said operating application 2012-OI -04 1 1005 155 10 15 20 25 30 19 334 and the 330 and entering the space 233, 333 between the outer 234, inner 222, 322 the bottom constitutes the storage container 230, where the inner bottom 222, 322 constitutes the bottom of the collection container 220, 320. simple construction with both containers 220, 300, two containers which during operation are arranged separately.
    Such a construction generally allows a 230; 320, 330 in one and the same combination container 200, rather than as This is preferred because it is difficult to install two such separate containers completely or partially buried in the ground 115 without problems arising with relative sliding and consequent leaks.
