Background
Sewage treatment: the sewage is purified to reach the water quality requirement of being discharged into a certain water body or being reused. Sewage treatment is widely applied to various fields such as buildings, agriculture, traffic, energy, petrifaction, environmental protection, urban landscape, medical treatment, catering and the like, and is also increasingly advanced to daily life of common people, and sewage in villages and small towns mainly consists of domestic sewage and agricultural wastewater. 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 for developing clean new energy in rural areas, protecting human living environment, promoting sustainable development of rural economic society and the like.
The sewage treatment is generally classified into production sewage treatment and domestic sewage treatment according to the classification of sewage sources. The production sewage comprises industrial sewage, agricultural sewage, medical sewage and the like, and the domestic sewage is sewage generated in daily life, and refers to complex mixtures of various forms of inorganic matters and organic matters, and comprises the following steps: floating and suspended large and small solid particles, colloidal and gelatinous dispersions and pure solutions.
At present, in the process of treating oily sewage, oil stains in the oily sewage are easy to adhere to the surface of the pipe wall of a drainage pipeline and are not easy to remove, so that in the long-term use process, particles are promoted to adhere to the inner wall of the pipeline, the inner diameter of the pipeline is reduced as time passes, and the drainage efficiency of the drainage pipeline is reduced.
