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 increasingly used in daily life of common people. 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. There are two types of water pollution, based on the nature of the water pollution: one is natural pollution; the other is artificial pollution, and the current water body is greatly damaged by the artificial pollution. Water pollution can be mainly classified into chemical pollution, physical pollution and biological pollution according to different pollution impurities. The pollutants are mainly: industrial waste water discharged untreated; domestic sewage discharged without treatment; farmland sewage using a large amount of fertilizers, pesticides and herbicides; industrial waste and domestic garbage piled beside river; water and soil loss; mine sewage.

When sewage is treated in narrow artificial watercourses, a method of manually and directly scattering a sewage treatment agent is generally adopted, but when the sewage treatment agent is manually scattered, the scattering amount is not easy to control, a large amount of sewage treatment agent is wasted or the sewage treatment is not thorough, and the problem that the addition amount of the sewage treatment agent is not well controlled is further caused because the flow rate of river water is different.
