Yes With the increasingly serious problem of sewage treatment, sodium acetate has been widely used as a supplementary carbon source for denitrification process in sewage treatment plants. Its low-temperature crystallization can domesticate denitrifying sludge, which has an impact on sewage treatment plants and can obtain higher specific denitrification rate. In the city, it is also called sewage treatment plant or sewage plant, and it is usually called the treatment station located in the factory. When sewage enters the urban drainage pipeline, the treatment station is actually a pretreatment facility.
