Background

The domestic sewage has fixed components, mainly contains organic matters such as carbohydrate, protein, amino acid, fat and the like, is more suitable for the growth of bacteria, and becomes a place for the survival and propagation of bacteria and viruses; but the domestic sewage generally does not contain toxicity, has certain fertilizer efficiency and can be used for irrigating farmlands. The agricultural wastewater has various components, and different treatment methods are needed for wastewater in villages and towns with different development targets in different seasons, different places and different development targets. In order to reduce the discharge amount and complexity of sewage during sewage treatment, the construction of methane tanks which are being popularized vigorously by China is combined to separate toilet flushing water (black water) from other domestic water (grey water). The grey water is treated by a natural purification system, and the black water and human and animal excreta are treated by an anaerobic methane tank, so that the discharge amount, complexity and treatment cost of sewage can be reduced, and the method has important significance in developing rural clean new energy, protecting human living environment, promoting sustainable development of rural economic society and the like. The sludge reflux belongs to a link in the sewage treatment process, generally adopts the reflux of a sludge pump, and has the defects that: high energy consumption, easy blockage and difficult maintenance.
