Description

TECHNICAL FIELD

[0002] Water pollution is water that has been contaminated by harmful chemicals, which reduces or destroys its usefulness and pollutes the environment. When organic matter in sewage is decomposed by microorganisms, it consumes oxygen in the water, affecting the life of aquatic organisms. After the dissolved oxygen in the water is exhausted, anaerobic decomposition of organic matter occurs, producing hydrogen sulfide, mercaptans and other unpleasant gases, which further deteriorate the water quality. Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging into a water body or for reuse. Currently, the treatment of contaminated water usually includes physical treatment, biological treatment and three-stage treatment. The physical treatment is to filter and remove the solid pollutants in the suspended state in the contaminated water. The existing physical treatment device usually uses a screen filtration method, i.e. filtering through a screen or a grid. This filtering method cannot effectively filter the sewage, and the internal structure is mostly fixedly arranged, so that the waste produced by filtration is difficult to clean. SUMMARY
