[0002] Rural wastewater treatment has multiple benefits for the ecological environment, economic development, and residents' lives. Direct discharge of untreated wastewater can lead to eutrophication, soil pollution, and drinking water safety risks. Wastewater treatment can reduce the spread of pathogens, lower the incidence of infectious diseases, improve water quality, and restore the ecological balance of rural areas. Wastewater treatment can also reduce mosquito breeding, improve the appearance of villages, and create a more livable environment for rural residents.

[0033] Working Principle: When this utility model is in operation, wastewater first enters the coarse filtration tank 1 through the inlet pipe, undergoes the first stage of filtration through the coarse filter screen 12 to filter out large impurities, and then enters the fine filtration tank 2 through the lift pump 13 and wastewater pipe. In the fine filtration tank 2, wastewater undergoes the second stage of filtration through the fine filter screen 14 to filter out small impurities, and then enters the equalization tank 3 through the wastewater pipe. In the equalization tank 3, wastewater and sludge are separated in the first stage by entering the hydrolysis acidification tank 4 through the lift pump 13 and wastewater pipe. The sludge enters the sludge storage tank 8 through the sludge pipe, and the wastewater enters the combined production tank through the wastewater pipe. In the treatment tank 5, sewage and sludge are further separated sequentially through the anaerobic zone 15, the anoxic zone 16, the aerobic zone 17, and the sedimentation zone 18.

In the sedimentation tank 6, chemicals are first added through the dosing tank 19, and the sludge and sewage are mixed by the mixer 21 and finally separated and enter the sludge scraping tank 20. The sludge is fed into the sludge storage tank 8 by the sludge scraper 22, and the sewage enters the filtration tank 7. After filtration in the filtration tank 7, the sewage enters the disinfection tank 10 and flows out, while the sludge enters the sludge dewatering tank 9 through the sludge storage tank 8 for dewatering and is then discharged.
