[0002] Sewage filtering refers to removing pollutants such as suspended solids, organic matter and microorganisms in sewage by physical, chemical or biological means to improve water quality and reduce environmental impact. Physical filtration is to separate large particulate matter, suspended solids and sediment from sewage by using filters, gratings, sedimentation tanks and other equipment to achieve preliminary purification. Common physical filtration equipment includes sand filters, fiber filters and magnetized filters. Chemical filtration removes dissolved pollutants and colloidal substances in sewage through chemical reactions. Common chemical treatment methods include coagulation, neutralization and oxidation-reduction. For example, coagulation involves adding flocculants to aggregate small particles in sewage into larger flocculent substances, which are then removed by sedimentation or flotation. Biological filtration uses the metabolic action of microorganisms to decompose organic matter and ammonia nitrogen in sewage into harmless substances to achieve deep purification. Biological filtration is usually achieved through bioreactors and biofilms.

[0003] In the prior art, sewage filters are generally divided into pre-filtering ends, filtering sections and post-filtering sections. The pre-filtering end is mainly used to filter large impurities.
