The pollutants in these water bodies mainly come from domestic sewage, agricultural non-point source pollution, livestock and poultry breeding pollution, etc. By implementing technical measures such as source control and sewage interception, endogenous treatment, water system connection, and ecological restoration, the pollutants in the water bodies can be effectively removed, the natural functions of the water bodies can be restored, and water resources can be protected. At the same time, the treatment of rural black and odorous water bodies is not only the solution to environmental problems, but also an important part of rural revitalization, and its significance is great.

[0003] However, most of the existing rural black and odorous water body purification devices are domestic sewage → regulating tank → purification tank → discharge, and their purification tanks only have the functions of sedimentation and filtration, and the filtration only depends on the natural flow of the internal water body. Their purification efficiency for rural black and odorous water bodies is low, and the sludge generated during the purification process is not easy to salvage and process, and is easy to accumulate in the purification tank, causing blockage.

The water inlet 2 is connected to the regulating pool through a pipeline, the water outlet 3 is connected to the purification pool through a pipeline, and the aeration ports 5 are connected to the air duct of the same aeration fan (installed on the ground). The interior of the purification tank main body 1 is as Figure 3As shown in the figure, a sundry removal tank 7, an aerobic filter bed tank 8, a packing flow tank 9 and a sedimentation tank 10 are arranged from front to back, and each tank body is separated by a partition plate with water permeable holes reserved. A collection tank 6 (with an open top and water permeable holes reserved on the side wall) is also arranged at the water inlet 2 of the sundry removal tank 7, and the collection tank 6 is fixed on the inner side wall of the sundry removal tank 7 (there is a distance of about half the height of the sundry removal tank 7 between the bottom wall of the collection tank 6 and the inner bottom wall of the sundry removal tank 7). Multiple layers of aerobic filter beds 11 are arranged in the aerobic filter bed tank 8. The packing flow tank 9 is filled with flowing packing, and a packing sieve cover 16 is arranged at the top (to prevent the flowing packing from flowing to other areas). The disinfection tank 14 is installed and fixed on the inner side wall of the sedimentation tank 10 corresponding to the collection tank 6, and the rear side wall of the disinfection tank 14 is directly connected to the water outlet 3. The top of the disinfection tank 14 is open, and there is a water passing port at the bottom wall. A chemical addition pipe 15 is arranged above the disinfection tank 14. One end of the chemical addition pipe 15 is connected to an external chemical addition tank, and the other end bends downward from directly above the disinfection tank 14 into the disinfection tank 14 after passing through the notch at the top of the purification tank body 1.

[0029] The sludge return structure includes a sludge return pump 12, a sludge pipe 13, a sludge filter 17 and a return water pipe 18; the sludge return pump 12 is arranged at the bottom of the sedimentation tank 10 and is communicated with the collection tank 6 through the sludge pipe 13. The sludge filter 17 is arranged on the sludge pipe 13. One end of the return water pipe 18 is fixedly connected to the sludge filter 17, and the other end is arranged at the bottom of the packing flow tank 9. After the sludge water is sucked by the sludge return pump 12, it is sent into the collection tank 6 through the sludge pipe 13. At the same time, part of the water in the sludge water enters the bottom of the packing flow tank 9 through the sludge filter 17 and the return water pipe 18 for re - filtration.

[0030] The spray circulation device includes a circulation water pump 19, a water delivery pipe 20, a water distribution coil pipe 21, spray heads 22 and a bracket 23: the circulation water pump 19 is arranged at the bottom of the aerobic filter bed tank 8 and is connected to the water distribution coil pipe 21 above the aerobic filter bed 11 through the water delivery pipe 20. The water distribution coil pipe 21 is horizontally laid and is fixed on the top of the aerobic filter bed tank 8 through the bracket 23. The spray heads 22 are arranged at the bottom of the water distribution coil pipe 21, and a plurality of them are evenly arranged.

[0031] In the specific implementation of this embodiment:

[0032] The overall purification process of the purification tank is as follows: domestic sewage - regulating tank - purification tank - clean water tank - discharge for use. There is a lift pump in the regulating tank, and the domestic sewage in the regulating tank is sent into the collection tank 6 of the purification tank through the lift pump in the regulating tank (the lift pump is associated with the liquid level gauge of the regulating tank, with low liquid level protection, starting at medium liquid level, and stopping when the liquid level in the purification tank is high). After overflowing into the main body of the purification tank, it successively passes through the debris removal tank, aerobic filter bed tank, packing flow pool and sedimentation tank, and is disinfected by adding medicine in the disinfection tank, and then enters the clean water tank from the water outlet. When the liquid level in the clean water tank reaches the high level, the regulating tank stops sending water to the purification tank. The purification tank works 4 - 6 cycles per day, and the operating cycle time interval is automatically adjusted according to the actual water volume. The water inlet time for each cycle is based on filling the clean water tank. The aeration time is 90 minutes, the sedimentation time is 60 minutes, the discharge time is 60 minutes, and the idle time is 30 minutes. And when the aeration fan has not run continuously for 12 hours, it will automatically start aeration for 10 minutes.

[0033] When the sludge return structure is in use, the sludge return pump 12 is turned on, and the sludge at the bottom of the sedimentation tank is transported to the collection tank 6. The sludge and debris at the bottom of the collection tank 6 are salvaged and cleaned every once in a while.

[0034] When the spray circulation device is in use, the circulation water pump 19 transports the water body at the bottom of the aerobic filter bed tank 8 to the water distribution coil 21 at a high place through the water delivery pipe 20 for spraying. And during the spraying process of the water, it is in full contact with the air, increases its own oxygen content and then falls back into the aerobic filter bed tank 8, and forms an internal water circulation in the aerobic filter bed tank 8, increasing the flow velocity in the up and down directions, thereby increasing the number of times of filtration of the aerobic filter bed 11.

[0035] Embodiment 2

[0036] The overall structure of the purification tank is as described above. One end of the sludge pipe 13 of the sludge return structure is connected to the sludge return pump 12, and the other end passes through the top slot 4 of the purification tank and is directly connected to the external sludge collection tank, and the sedimented sludge at the bottom of the sedimentation tank is directly discharged to the outside. At the same time, the water in the discharged sludge is recovered through the sludge filter 17 and the return pipe 18.

[0037] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the creative purpose of the present invention, they should all fall within the protection scope of the present invention.
