Background

The rural domestic sewage mainly comprises toilet flushing sewage and waste water of clothes washing, rice washing, vegetable washing and bathing. The sewage is mainly domestic waste and human excrement, generally contains no toxic substances, often contains nutrient substances such as nitrogen, phosphorus and the like, and also contains a large amount of bacteria, viruses and parasitic ova. Because the difference of the water quality and the water quantity of the domestic sewage in different rural areas such as living habits, life styles, economic levels and the like is large, the sewage has the following characteristics and problems: (1) the sewage is distributed dispersedly, the related range is wide, the randomness is strong, the prevention and the treatment are very difficult, a pipe network collection system is not perfect, the sewage is discharged in a rough manner, and basically no sewage treatment facility exists; (2) the rural water consumption standard is low, the sewage flow is small, and the change coefficient is large (3.5-5.0); (3) the sewage has complex components, but the concentration of various pollutants is low, and the biodegradability of the sewage is strong. Because rural domestic pollution sources are dispersed and not easy to concentrate, the environment protection consciousness of village and town residents is poor, and the economic level is relatively laggard, the treatment is also difficult, so that the rural domestic sewage becomes an important pollution source influencing the water body environment quality. At present, 75% of natural and artificial water bodies in China are eutrophicated, and the trend is continuously worsening.

An effective solution to the problems in the related art has not been proposed yet.
