The method provides a new challenge for rural ecological civilization construction, and rural sewage treatment is a basic project for improving rural living environment and improving the quality of life of farmers. Rural sewage generally comprises two parts, namely grey water and black water, wherein the grey water refers to domestic sewage with lower concentration, such as kitchen water, washing water and rinsing water (excluding toilet flushing water); the black water generally refers to high concentration domestic sewage of toilet flushing excrement. Meanwhile, a targeted sewage treatment system is not built, so that resources are not reasonably utilized, and the water resource waste is serious.
The present village and town sewage treatment mode in China includes a method for treating sewage in a town drainage pipe network, a method for treating villages in a centralized manner and a method for treating the sewage in a scattered manner, which are summarized by the application discussion of the rural sewage treatment technology in different areas of China (No. 48, no. 8 of No. 4 month in 2022).
