    Follows the wastewater, dissolved in the wastewater and / or in gaseous form, to the pump station and causes several problems there.
    A major problem for the residents in the area is that hydrogen sulphide creates a very unpleasant odor that is easily spread in the residential area as a result of pumping stations not being completely airtight. A major problem for the pumping station as such is that the hydrogen sulphide causes corrosion on both metal components and concrete components. The group of metal components includes, for example, pumps, electronics, sensors, struts, etc., and the group of concrete components includes, for example, pump sumps, large pipelines, etc.
    In addition, hydrogen sulphide, when present in high concentrations in the air, is very harmful by inhalation. The hydrogen sulphide can lead to paralysis of the respiratory system, with consequent unconsciousness, in those who inhale air with a high concentration of hydrogen sulphide. This can cause problems for service personnel.
    Known ways of trying to solve the above-mentioned problems are, for example, adding oxygen-containing chemicals to the wastewater, minimizing the residence time in the pipelines by pumping the wastewater from the respective households to the pumping station, etc.
    Brief Description of the Objects of the Invention The present invention aims at providing an improved wastewater treatment plant and method for reducing high levels of harmful gases in wastewater.
    A basic object of the invention is to provide an improved wastewater treatment plant of the initially defined type, which is easy to install and requires little or no maintenance.
    A further object of the present invention is to provide a waste water system which prevents various components present in the pump station from being subjected to corrosion. It is another object of the present invention to provide a wastewater treatment plant which does not emit any unpleasant odor.
    Brief description of the features of the invention According to the invention, at least the basic object is achieved by means of the initially defined wastewater treatment plant and the method, which have the features defined in the independent claims. Preferred embodiments of the present invention are further defined in the dependent claims.
    According to a first aspect of the present invention, there is provided a wastewater treatment plant of the initially defined type, which is characterized in that the wastewater treatment plant comprises a stationary spreading plate arranged directly below said inlet opening and arranged vertically at a level above said outlet opening. has an upper surface arranged to receive and disperse waste water entering from the inlet opening and a peripheral edge over which the waste water is arranged to flow.
    According to a second aspect of the present invention there is provided a method comprising the steps of receiving in a container a mixture of a flow of incoming wastewater and a flow of noxious gases via an inlet opening, surface of a spreading plate arranged in the container, incoming wastewater flow towards an upper spreading flow the dispersed wastewater flow over a peripheral edge of the wastewater flow over the upper surface of the spreading plate, the spreading plate whereupon the harmful fluids react with oxygen and dissolve in the wastewater, and the effluent effluent via the effluent.
    Thus, the present invention is based on the insight that by increasing the contact area between the wastewater and an air volume present in the container, when the wastewater enters the container, the harmful fluid will be more easily released from the wastewater and react with the oxygen. In the container and then dissolved as a harmless fluid in the wastewater.
    According to a preferred embodiment of the present invention, the spreading plate is connected to and projects at an angle from an inner surface of the container. This means above all that the spreader plate and the container can be manufactured in one piece, which simplifies handling and installation.
    According to a preferred embodiment, the upper surface of the spreading plate is flat and has an inclination relative to a horizontal plane, the inclination angle being more than 30 degrees and less than 60 degrees. A flatter slope means that solid material in the wastewater risks accumulating on the spreading plate and a steeper slope means that the incoming flow of wastewater does not spread sufficiently and thus there is a risk that the contact surface between the wastewater and the container's air volume is not increased to the desired extent.
    Preferably, the spreading plate further comprises a rim surrounding at least a part of the upper surface of the spreading plate, said peripheral edge of the spreading plate being constituted by the upper edge of the rim. The rim means that the wastewater is dammed up and thus a greater distribution of the incoming wastewater is obtained.
    It is also preferred that the waste water system comprises an aerator unit arranged on a bottom of the container, the aerator unit being arranged to supply oxygen to the waste water which the container is intended to accommodate and to the air space in the container. The aerator unit provides an additional supply of oxygen to assist in the reduction of harmful fluid in the wastewater.
    Additional advantages and features of the invention will be apparent from the other dependent claims and from the following detailed description of preferred embodiments.
    Brief Description of the Drawings A more complete understanding of the above and other features and advantages of the present invention will become apparent from the following detailed description of preferred embodiments with reference to the accompanying drawings, in which: FIG. Fig. 2 is a schematic, sectional perspective view of a wastewater treatment plant according to an invention according to a first embodiment, Fig. 2 is a schematic, sectioned side view of a wastewater treatment plant according to the invention according to a second embodiment, Fig. 3 is a schematic top view of the wastewater treatment plant according to figure 2, and Fig. 4 is a schematic, sectional perspective view of the wastewater treatment plant according to figures 2 and 3.
    DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS The present invention relates generally to the management of wastewater, for example in connection with a pumping station (not shown). Wastewater refers in particular to wastewater from households, which wastewater includes solid material in the form of organic material.
    Reference is initially made to Figure 1, which shows a wastewater treatment plant according to the invention, generally designated 1. The wastewater treatment plant 1, in practice constitutes a well to a pumping station (not shown), whereby harmful substances such as hydrogen sulphide can be neutralized / reduced by reacting with oxygen and dissolving. in the wastewater, and thus prevented from entering the pumping station in the form of a harmful fluid. It should be pointed out that the wastewater treatment plant 1 according to the invention should preferably be located in close connection with the pump station, otherwise there is a risk that the harmful fluid will develop again during movement to Dock, the distance should be long enough to ensure the pumping station. that the neutralized hydrogen sulphide that has been converted to sulfuric acid should be dissolved in the waste water. A suitable distance is about 20 meters. Oxygen present in the wastewater downstream of the wastewater treatment plant, for example in said pumping station, will move upstream into the wastewater treatment plant and thereby supply oxygen to the wastewater housed in the wastewater treatment plant.
    The waste water system 1 comprises a container 2 for temporarily housing waste water, the container 2 comprising a bottom 3, a circumferential wall shell 4 extending upwards from said bottom 3 with an inner surface 5 and a free upper edge 6. Furthermore, the container comprises an inlet opening 7 for incoming flow and an outlet opening 8 for outgoing flow. Said inlet opening 7 and said outlet opening 8 are preferably arranged in the wall shell 4 of the container 2, however it is conceivable that said outlet opening 8 is arranged in the bottom 3 of the container 2. In case the outlet opening 8 is arranged in the wall shell 4, the outlet opening 8 should be as close as possible to the bottom 3 of the container 2 in order to prevent the accumulation of solid material in the container 2.
    Furthermore, the bottom 3 of the container 2 can be arranged inclined towards the outlet opening 8 to further counteract accumulation of solid material in the container 2. Furthermore, said inlet opening 7 must be arranged at a level above said outlet opening 8. Preferably the container 2 is made of fiberglass, plastic, or other such material which is not prone to corrosion.
    The inlet opening 7 is intended to be connected to an incoming pipeline 9, a mixture of a flow of incoming wastewater and a flow of harmful fluids being led into the container 2, furthermore the outlet opening 8 is intended to be connected to an outgoing pipeline 10 to allow outflow of outgoing wastewater. The harmful fluids may be dissolved in the wastewater or in gaseous form.
    The waste water plant 1 according to the invention further comprises a stationary spreading plate 11 which is arranged directly below said inlet opening 7 and arranged vertically at a level above said outlet opening 8. The spreading plate 11 has an upper surface 12 arranged to receive and receive from the inlet 7 the waste water and a peripheral edge 13 over which the waste water is arranged to flow. During operation, the incoming flow of waste water 10 will leave the inlet opening 7 and flow / splash down on the upper surface 12 of the spreading plate 11, whereupon the flow will spread over said upper surface 12. By harmful fluid is meant in the first hand (H25) be synonymous terms in this context. hydrogen sulphide in gas phase or in liquid phase, which is to be considered When the wastewater enters the container 2, the hydrogen sulphide in gaseous form will also leave the inlet opening 7 and collect in the air space present above the wastewater housed in the container 2.
    When the waste water flows / splashes down on the upper surface 12 of the spreading plate 11, spreads over said upper surface 12, and then flows over the peripheral edge 13 of the spreading plate 11 and further down towards the bottom 3 of the container 2, the contact surface / interface between the waste water and the air space in the container 2.
    This in turn means that the hydrogen sulphide present in the liquid phase in the wastewater will more easily be transferred to the gas phase in the air space above the wastewater.
    In the moist air layer above the wastewater in the container 2, the hydrogen sulphide will react / oxidize with the oxygen available and form sulfuric acid, the formula H25 + 202 -> H2SO @ according to where the sulfuric acid condenses on the inner surface 5 of the container 2. Thus, the content has harmful fluids in the container 2 flows down and is dissolved in the wastewater. reduced and instead wastewater with a low concentration- ÜQSO4) has been obtained.
    Preferably, the spreader plate 11 is connected to and tration of sulfuric acid projects at an angle from the inner surface 5 of the container 2, as shown in Figure 1. According to an alternative embodiment not shown, the spreader plate 11 may be a plate with a circumferential peripheral edge spaced from the inner surface of the container, for example, in this embodiment not shown, the spreading plate 11 can be conical with a cone angle between 60 and 120 degrees. In the embodiment shown in Figure 1, the upper surface 12 of the spreading plate 11 is flat and has an inclination relative to a horizontal plane, which inclination angle is preferably more than 30 degrees and less than 60 degrees. In an alternative embodiment not shown, the peripheral edge 11 of the spreading plate 11 can be upwardly arcuate. Reference is now made in particular to Figures 2-4, which jointly show a wastewater treatment plant 1 according to the invention according to a second, preferred embodiment.
    According to this embodiment, the spreading plate 11 comprises a rim 14 which surrounds at least a part of the upper surface 12 of the spreading plate 11.
    The rim 14 projects upwards from the upper surface 12 of the spreading plate 11, preferably perpendicularly, an upper edge of the rim 14 forming at least a part of the peripheral edge 13 of the spreading plate 11. The purpose of the rim 14 is to temporarily dam the waste water flow hitting the upper surface 11 of the spreading plate 11. 12, so that it is ensured that the waste water flow flows over as long a part as possible of the peripheral edge 13 of the spreading plate 11. In the embodiment shown, the upper edge of the rim 14 is sawtooth-shaped, however the upper edge of the rim 14 may have other shapes, such as straight arcuate, etc.
    Furthermore, the diffuser plate 11 preferably comprises at least one diffuser plate 15 which is connected to and which projects. The purpose of the at least one diffuser plate 15 is to further outwards at an angle to the upper surface 12 of the diffuser plate 11 ensure that the waste water is spread evenly over the upper diffuser plate 11 surface 12. In the embodiment shown, there are two separate spreading plates 15, each directed downwards-outwards on each side of a center line of the spreading plate 11.
    In the embodiment shown, a pipe bend 16 is arranged in connection with the inlet opening 7, in order to direct the incoming waste water flow towards the upper surface 12 of the spreading plate 11. In the embodiment shown, the pipe bend 16 is a 90 degree pipe bend facing downwards. However, it is also conceivable that said pipe bend is turned upwards to obtain greater dispersion when the wastewater leaves the pipe bend and more splashing effect when the wastewater hits the diffuser plate 11 over surface 12. The presence of a pipe bend is preferred when the incoming sewage flow is pressurized.
    The waste water system 1 preferably comprises a removable lid 17, see figure 2, which in the assembled state is tightly closed against the container 2 in the area of the upper edge 6 of the container 2. The lid 17 must be connected during normal operation, except during service, with the container 2 to prevent the spread of foul-smelling gas.
    In the embodiment shown in Figures 2-4, the waste water system 1 preferably also comprises an aerator assembly 18 arranged on the bottom 3 of the container 2. The aerator assembly 18 is arranged to supply air bubbles to the waste water which the container 2 is intended to accommodate, in order to supply oxygen to the air space above the wastewater. The aerator unit 18 can be operated continuously or intermittently, depending on the supply of oxygen in the container 2. An air line (not shown) supplies the aerator unit 18 with pressurized air from a compressed air source, 18 is in the shown embodiment a so-called plate aerator, for example an external compressor. The aerator assembly comprises a diaphragm with a large plurality of holes / slots through which the pressurized air is forced to form small air bubbles. However, it should be mentioned that other types of aerator units can also be used. Preferably, the aerator assembly 18 is vertically arranged at a level below the outlet opening 8, in order to ensure that waste water covers the aerator assembly 18.
