Background
With the vigorous development of economy in rural areas in China, living conditions of rural residents are continuously improved, and meanwhile, domestic sewage generated in the rural areas is increasingly increased. According to the first national pollution source general survey publication, the total amount of water pollutants discharged in rural areas before 10a in China is about 50% of the total national discharge amount, wherein the discharged chemical oxygen demand, total nitrogen and total phosphorus respectively account for about 43%, 57% and 67% of the total national discharge amount. However, by the end of 2018, the sewage treatment rate of country is only 18.75%. A large amount of untreated domestic sewage is discharged wantonly, which not only causes serious pollution to rural ecological environment, but also has great hidden trouble for safe drinking water burying of rural residents. With the continuous importance of the government in China on the improvement of rural human living environment, the effective treatment of domestic sewage in rural areas is urgent.
At present, the activated sludge process is the main method in the common process in the village and town sewage treatment market in China. The activated sludge process has higher requirements on the stability of water quality and water quantity, and the fluctuation of the water quality and the water quantity can directly influence the removal efficiency of pollutants. Because the sewage collection mode of most villages and towns in China is combined with rain and sewage, rural sewage treatment facilities in areas with abundant rain water meet rain days, and rain and sewage exceeding the design flow is usually directly discharged from overflow ports of lifting wells or regulating ponds, so that the water environment is seriously influenced; some village sewage stations even cause serious hydraulic flushing to a biological pool due to design defects, so that microorganisms are ineffective and lost, and the sewage treatment function is lost. At present, the common village and town sewage treatment process in China does not have the functions of treating and buffering rain wash, and the common countermeasure is to release rain and sewage loss, so that the ecological environment of rural water is seriously influenced.
