Background

At present, more than 60 million administrative villages and more than 250 million natural villages exist in China, 2 hundred million farmers live in residence and nearly 8 million population, the sewage discharge amount is huge, most of sewage is directly discharged into peripheral water without treatment, serious harm is caused to the ecological environment, and the sewage becomes an important pollution source of a new regional water environment.

In addition, the living environment of rural areas in China is quite special: the economic development of a part of rural areas is fast, the population is dense, the vacant areas are small, the land resource price is high, the land acquisition procedure is complicated, and the centralized sewage treatment scheme is difficult to implement. And in addition, the living in some rural areas is dispersed, the terrain and the topography are complex, the construction difficulty of a sewage pipe network collection system is high, and the cost is high. Furthermore, with the acceleration of urban construction, a large amount of rural population is shifted to towns, the "hollow village" and the "hollow house" become normal state gradually, and the water inflow design may be difficult to achieve by building a centralized sewage treatment facility, which causes resource waste.

In view of the dispersed division of rural land, the rural sewage treatment should change the traditional centralized collection treatment concept and change to the adoption of an efficient and reliable distributed sewage treatment system for on-site treatment. At present, China develops some research works in the aspect of rural sewage treatment, but the current technical level still has the defects of high investment cost, large floor area, unstable treatment and operation, poor water production quality, poor popularization and the like, so that the research results are difficult to transplant and popularize.
