[0002] Sewage treatment refers to a process for treating sewage, which includes separation treatment, conversion treatment and dilution treatment. Separation treatment: Through the action of various external forces, pollutants are separated from wastewater. Generally speaking, the chemical nature of pollutants is not changed during the separation process. Conversion treatment: Through chemical or biochemical effects, the chemical nature of pollutants is changed to be harmless substances or separable substances, which are then separated and removed. Dilution treatment: Through dilution and mixing, the concentration of pollutants is reduced to achieve the purpose of harmlessness. When treating rainwater and sewage mixed water and black and smelly water bodies, it is necessary to filter the debris in the rainwater and sewage mixed water and black and smelly water bodies. After the filter used for filtration has been used for a period of time, debris is easy to accumulate on the filter, affecting the use of the filter.
