Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, while domestic sewage is the sewage produced in daily life, which refers to the complex mixture of various forms of inorganic and organic substances.

In the prior art, there are a variety of sewage treatment processes, and for sewage containing insoluble solid particles in the water body, a sedimentation and filtration process is usually used for preliminary treatment of the sewage to separate the solid particles in the sewage from the water body. In the precipitation filtration process, the filter screen is one of the commonly used treatment equipment, and the sewage is passed through the filter screen to achieve solid-liquid separation.
