As shown in FIG. 1 , the point source sewage treatment device of the present invention includes a water tank 2 , and the water tank 2 is installed in water to ensure that polluted water will not overflow the water tank 2 . The water tank 2 can be made of a flexible box or a hard box. Since the internal and external water levels are basically the same and the water pressure is basically equal, the water tank 2 can be made of a material with a thinner wall thickness. If a flexible box is used, a flexible rain cloth can be used. Or plastic tape and other waterproof materials, such as the use of hard boxes, can be made of thin steel or fiberglass and other materials. The use of a flexible box can form a "floating" structure, directly floating the point source sewage treatment device in the river, flexible movement, and convenient recycling; using a hard box, the bottom of the water tank 2 is located on the river bed, forming a The "floor type" structure facilitates the treatment of fixed sewage sources. But no matter it is a "floating" structure or a "floor type" structure, the opening of the water tank 2 will be higher than the water level of the river, so as to ensure that the polluted water will not overflow the water tank 2.

As shown in Figures 1 and 2, the inside of the water tank 2 is provided with an aeration device 23. When treating sewage, the sewage in the water tank 2 can obtain sufficient dissolved oxygen. The aeration device 23 can be an aeration tube , is installed in the bottom of water tank 2, also can select the surface aeration mode for use. The water tank 2 is provided with a biochemical filler 3, and the biochemical filler 3 is arranged in the water tank 2 by hanging or random stacking, etc., preferably, the biochemical filler 3 is a three-dimensional elastic filler, biochemical cotton or combined filler, and is evenly distributed In the water tank 2, using the biochemical treatment method to treat sewage can cause a large number of microorganisms to grow on the surface of the biochemical filler 3, forming a relatively stable biofilm to purify the sewage.

As shown in FIG. 1 , the water tank 2 is provided with a water inlet pipe 21 and a water outlet pipe 22 , and the water outlet pipe 22 is provided with a first filter device 4 . Preferably, the first filter device 4 is located in the water tank 2, and can also be arranged outside the water tank 2 in series with the water tank 2, and the filter layer of the filter device 4 can be made of filter cotton or other filters capable of filtering The filter medium is composed of suspended particles in the water quality, and the filter layer can filter the residual suspended particles in the water body after biochemical treatment. The water inlet pipe 21 is provided with a second filtering device 211, and the second filtering device 211 can be located in the water tank 2, or can be arranged outside the water tank 2 in series with the water tank 2, and the second filtering device 211 The filter device 211 is preferably a grid, which can filter larger suspended particles. Preferably, a water pump is provided on the outlet pipe 22 .

As shown in Fig. 1 and Fig. 2, a floating panel 1 is also arranged on the water tank 2, and a soilless cultivation technique can be used to plant aquatic plants on the said floating panel 1, and decorative articles can also be arranged, preferably, the said floating panel 1 is in the form of The aquatic plants can be fixed on the net, and the roots of the aquatic plants can reduce and enrich nitrogen, phosphorus and organic substances in the water body through absorption and adsorption. When using a flexible box, the water tank 2 is connected with the floating tube 11 or the floating plate and floats in the water, the floating panel 1 is connected above the floating tube 11, and the floating panel 1 and the water tank 2 share the floating tube 11 or As for the floating plate, the floating tube 11 or the floating plate is made of a material with a density lower than that of water, and a hollow tube or a foam tube with greater buoyancy can be selected. Because the floating panel 1 and the water tank 2 are immersed in water, they can generate buoyancy, and then by means of the buoyancy of the floating tube 11 or the floating plate, it can be ensured that the floating panel 1 and the water tank 2 can float in the water.

The point source sewage treatment device involved in the utility model is especially suitable for treating point source sewage, such as the sewage discharged into the river channel and lake from the sewage discharge point around the river channel and lake. Set near the sewage outlet.

When the utility model works, the polluted water body is lifted to the water tank 2 through a direct current or a water pump, and the biochemical filler 3 and aquatic plants are used for treatment. Especially when treating point source sewage, the water inlet pipe 21 can be directly connected with the sewage outlet of point source sewage in rivers or lakes, and the sewage can be concentrated and purified by the treatment device of the present utility model before being discharged into rivers or lakes , to avoid the spread of sewage in rivers or lakes. On the basis of biological contact oxidation and ecological purification technology, this process can also strengthen other processes such as subsequent filtration and precipitation. This technology can not only reduce the nitrogen, phosphorus and organic substances in the enriched water body through the absorption and adsorption of plant roots, but also use the large number of microorganisms formed on the surface of the biochemical filler 3 suspended under the floating panel 1 to purify the pollutants . The huge surface area of the biochemical filler 3 allows a large number of microorganisms to attach and grow, forming a relatively stable biofilm. By setting reasonable dissolved oxygen and residence time, the decomposition efficiency of high-concentration pollutants is improved. The treatment device of the present utility model can be used alone or in series in multiple stages. After the sewage is processed in one treatment device, it is discharged into the next-level treatment device through the outlet pipe 22, or discharged into rivers and lakes. By setting the filter device 4 on the water outlet pipe 22, the outlet water still containing suspended particles is intercepted and filtered, the content of suspended particles is reduced, and the transparency of the outlet water quality is improved.

The utility model can produce the following technical effects:

First: Introduce the concepts of "floating" and "floor type" in the utility model, and directly set point source sewage treatment devices in the river, saving civil engineering costs and not occupying land space; and because the water levels inside and outside the water tank 2 are basically the same , the outer wall is basically not under pressure, so when the "floating" structure is adopted, plastic tape or other cheap thin-walled materials are used to make the box. The whole device is low in cost, easy to move, and flexible in application. The cabinet is made of thin steel plate or fiberglass to meet specific environmental requirements.
