    The invention relates to methods and apparatus for treating wastewater and can be used in industry and in households.
    There is a known method for treating wastewater, which includes mixing wastewater with crushed waste, separating the mixture from the inorganic part, repeatedly filtering the mixture on filters containing activated carbon and coal, washing the filters with purified water and regenerating the filter material by heat treatment and returning it for reuse.
    A device for treating wastewater is known, which contains a tank for mixing wastewater with garbage, means for separating from the mixture of the inorganic part, a multistage filter with coarse and fine filters and a reactor for thermal regeneration of the filtering material C13 (
    A disadvantage of the known technical solutions is the possibility of clogging or sticking of filters and abrasion of filter material, which leads to the passage of contaminants through the filter thinly, cleaning them and entering them into purified water, as a result of which the cleaning efficiency decreases.
    The aim of the invention is to increase the efficiency of the wastewater treatment process by eliminating the possibility of clogging or sticking of filters and the abrasion of filter media. .
    The goal is achieved by the fact that according to the wastewater treatment method, which includes mixing wastewater with shredded waste, separating the inorganic part from the mixture, repeatedly filtering the mixture, washing the filters with purified water, regenerating the filtering material by heat treatment and returning it for reuse, into the filter the material is supplemented with polar substances and then the filter material is granulated.
    Alumina and / or silicon are used as polar substances.
    .
    The addition of polar substances is carried out by introducing waste or paper production wastewater.
    In the wastewater treatment device containing a tank for mixing wastewater with garbage, means for separating the inorganic part from the mixture, a multistage filter and a reactor for thermal regeneration of the filtering material, the multistage filter is made in the form of separate removable filter elements mounted on the chain transport device with the possibility hopping up.
    The multistage filter can be made in the form of bucket filters with open buckets fixed up on the transporting device, the walls and bottoms of which are perforated.
    The bottoms of the buckets are divided in a single-sided direction by partitions. ,
    The multistage filter can be made in the form of endless perforated belt conveyors with guides displaced under the coal relative to each other in the horizontal plane and with the earth. and unloading station oli.
    By separating the filtration process into several stages with pre-filtration, it is possible to mechanically and partially adsorbate the separation of sewage contaminants without clogging or sticking the perforated filter walls due to the fact that the contaminants adhere to particles of loose granular filter material and by tilting or turning the filter elements it is possible to remove contaminated filter media, release: perforated surfaces and filling them with fresh fi material that allows continuity of the process and increase its efficiency.
    Entering polar additives into the filtering material allows one to obtain an additional filtration effect due to polar electrostatic effects that contribute to wastewater treatment, and granulating the filtering material reduces its rubbing during the filtration process, which also contributes to an increase in the process efficiency.
    FIG. 1, 2 schematically presented the wastewater treatment device; in FIG. 3 shows a variant of the design of the pre-filter in FIG. 4 and 5 are versions of the design of filters for pre and fine cleaning; in fig. 6 shows section A-A in FIG. five.
    The device comprises a channel 1 for supplying wastewater, means 2 and 3 for supplying and grinding waste, means 4 for mixing waste and wastewater, made, for example, in the form of a system of gas nozzles, a collecting tank 5 in which a transporting device 6 is placed for removal - yellow inorganic impurities and a sieve 7 with a conveyor 8 to remove the floating organic part of the mixture for heat treatment. Behind the reservoir tank, a pre-filter 9 is installed, rotating in a countercurrent to the waste water passing through it. The pre-cleaning filter consists of individual filter elements 10,
    5 fortified on a chain conveyor 11..
    The advantage of this design of the rotating pre-filter is that it can
    0, the residence time of the filter elements in the wastewater can be adjusted, depending on the degree of saturation with a stream of water.
    Behind the pre filter
    5, a coarse filter 12 with filter elements 13 and a fine filter 14 with filter elements 15 are successively located. Filter design is coarse
    0 and fine cleaning may be similar to the design of filter. For pre-cleaning; The movement of the filters is also carried out in the counterflow to the flowing wastewater. For flushing fine filter
    5, a device 16 is provided having a means 17 for collecting and storing purified water, in which a means for heating it 18 is provided. A channel 19 located behind the fine filter serves to drain the purified water.
    9. Pre-filter can be made as separate open buckets 20, bottom
    5 21 which are perforated and which contain filtering material 22 fixed on the rotating device with the transport device 23 with the possibility of tilting. Unloading
    0 of the filtering material from the ladle to the regeneration furnace is carried out by the conveyor 24, and the loading by the conveyor 25.
    This filter design is for
    5, the pre-filtration allows the process to be easily controlled by passing the wastewater through an appropriate number of bucket elements.
    Pre-filter
    0 can also be made in the form of an endless bucket filter 26 (FIG. 4) immersed in a wastewater stream.
    The endless bucket filter consists of a conveyor belt 27, which is driven through the rollers Z8. On the tape, a series of open buckets 29 is strengthened, rigid bottoms of 30. Which may be square, rectangular, etc., side stacks, 31 are triangular. Separate buckets are interconnected by means of perforated walls 32. Each bucket can be divided into separate sections by partitions 33. This design is also applicable to the implementation of a fine filter. - Another design option for filters for prefine and fine cleaning would be to run them in the form of endless belt perforated conveyors 34 with guides 35 that are offset at an angle relative to each other, and loading .36 and discharge station 37 (Fig. 5). The conveyor 34 is driven by the rollers 38. The surface of the conveyor 34 is made with thickenings 39. There is a filter material 40 on it, on which soils 41 are deposited. The method is carried out as follows. The filter material regenerated by heat treatment is granulated to eliminate the attrition of coal dust and the associated clogging of filter towers and tanks. Before granulation, the filter material is cooled and milled, after which it is mixed with an organic binder and compacted in the appropriate device at a pressure of 1200 kg / cm. The compacted filter material is milled to form a fragmentation granulate that does not suffer significant abrasion. sewage flow,. To improve the adsorption, the filtering material (; coal j can be activated by heat treatment in a gas-tight reactor by introducing water vapor and / or zinc chloride into it. The resulting granules The activated activated filter material (coal) has good abrasion resistance and high adsorption capacity. To further improve the quality of the filter material used for wastewater treatment, polar additives are added to it. Example 1. Filter material (0 , 5-2 kg of alumina. After heat treatment, the resulting filter material is milled and granulated as described. Tests in wastewater treatment show improved wastewater treatment. Example 2. Into the filtering material (100 kg; 0.5-2 kg of silica was introduced. The subsequent operations are carried out as in Example 4. Tests show that the filtering material with the addition of silicon oxide has an increased cleaning effect. P RIM e p 3. Waste containing 20% waste paper is loaded into the heat treatment reactor of the filtering material. After the heat treatment, the resulting coal is cooled, crushed, mixed with an organic binder and compacted, and then ground to obtain a fragmentation granulate. The material obtained in this way has a high adsorption capacity. The device, in which the wastewater treatment method is carried out, works as follows. Sewage water enters through channel 1, means 2 and 3, respectively, feed and chop debris into channel 1. The wastewater is mixed with the garbage by means of the means 4. The resulting mixture enters the settling tank 5, in which the separation of water into inorganic water is carried out. (Heavy / and organic) stey. The inorganic part is removed by the transporting device 6, and the part that is left over through the sieve 7 is fed to the pre-filter 9 for cleaning. The light organic part of the conveyor 8 is removed from the precipitation tank 5 for heat treatment to the regeneration reactors of the filtering material. After pre-cleaning on the pre-filter 9, the waste water is further purified on the coarse filter 12 and finally cleaned on the fine filter 14. The purified water passes through channel 19 to use. The design of the filters provides for their continuous operation with the removal of contaminated filtrating material for regeneration and returning the regenerated and prepared filtering material during the cleaning process. The use of the invention makes it possible to increase the efficiency of the cleaning process by eliminating clogging or sealing of the filters, reducing the attrition of the filter material and the continuity of the cleaning process. 1 / V /
