[0002] The pollutants in sewage generally exist in three forms: suspended (including floating) state, colloid and dissolved state. The object of physical treatment of sewage is mainly suspended solids and part of colloids that may block the impeller of the water pump and the valve of the pipeline and increase the load of the subsequent treatment unit, so the physical treatment of sewage is generally also called solid-liquid separation treatment of wastewater. From the principle, solid-liquid separation of wastewater is mainly divided into two categories: one category is that the suspended solids in water are removed under certain restrictions; the other category is that the suspended solids are discarded under certain restrictions. However, in the existing filter process, large objects or impurities may hit the grating, causing damage or even breakage of the grating. This may require replacement of the grating or maintenance, and at the same time, the operation of the machine needs to be stopped during maintenance, thereby affecting the progress of the project.
