It is also called sewage treatment plant or sewage plant in the city. It is often called a processing station located in a factory. When sewage enters the urban drainage pipeline, the treatment station is actually a pretreatment facility. The general goal of wastewater treatment is to remove suspended solids and increase oxygen consumption (that is, to stabilize organic matter), and sometimes disinfection and further treatment are carried out. The treatment of industrial wastewater focuses on removing or transforming oils, suspended solids, heavy metals and organic substances that hinder the operation of urban sewage plants or have high residues, and adjusting pH value.
