[0002] Sewage filtration refers to the process of separating and removing solid particles, suspended matter, sediment and other impurities in sewage through physical or chemical methods. It is an important part of water treatment, which can effectively reduce environmental pollution and improve water quality. The purpose of sewage filtration is to remove solid matter and suspended matter in sewage during the treatment process to purify water quality, reduce pollutant concentration, prevent pipe and equipment blockage, and provide a good pre-treatment environment for subsequent water treatment processes.
