If the content of the phosphorus in the water body is too much, excessive propagation and growth of a large number of duckweed organisms and other similar organisms on the surface of the water body can be caused, so that the oxygen content and the dissolved oxygen content in the water are greatly reduced, and further, a large number of organisms, beneficial bacteria and microorganisms in the water body die, so that the water body is turbid, smelly and black. Therefore, the dephosphorization is the important factor in sewage treatment. Phosphorus removal refers to removal of phosphorus in sewage, and phosphorus generally exists in the sewage in the form of phosphate, so that phosphorus removal actually refers to removal of phosphate in sewage. The phosphorus removal method of domestic sewage can be divided into a primary sedimentation method, a secondary sedimentation method and chemical precipitation treatment. The chemical precipitation treatment is to add calcium, aluminum or iron compounds such as lime, alum, ferric chloride, etc. into the sewage to react with phosphate in the sewage to generate insoluble precipitate and remove the insoluble precipitate.
The content of phosphorus in domestic sewage and part of factory sewage is usually excessive and exceeds the standard. If the domestic sewage and part of factory sewage with excessive phosphorus content are directly discharged into the environment, other water sources can be seriously polluted. Therefore, the domestic sewage with excessive phosphorus content and exceeding standard and part of factory sewage need to be dephosphorized and discharged after reaching the standard and being qualified.
