Water treatment is the abbreviation for water supply treatment and wastewater treatment, and it is an important part of water industry science and technology.

Classification of water treatment methods
Generally divided into primary processing, secondary processing and tertiary processing (advanced processing, advanced processing).
Primary treatment is mainly pretreatment. Physical methods or simple chemical methods (such as preliminary neutralization of pH) are used to remove suspended solids, colloids, suspended oils and other pollutants in wastewater. The treatment level of the primary treatment is low, and generally does not meet the specified emission requirements, and the secondary treatment is still required.

The secondary treatment is mainly to clear the colloidal or dissolved organic pollutants that can be decomposed or oxidized, and more economical biochemical treatment methods are used. After the secondary treatment, the wastewater can generally meet the discharge standards, but there may be residual microorganisms, non-degradable organic matter, and inorganic salts such as nitrogen and phosphorus. They are not large in number and usually do not cause much harm to the water body.

Three-level governance is also called in-depth governance, and it is only used when there are special requirements. It is the secondary treatment of wastewater, and then use physical and chemical technology for further treatment, in order to remove soluble inorganic matter and indecomposable organic matter, remove various viruses, germs, phosphorus, nitrogen and other substances, and finally reach the surface water , Industrial water or water quality standards close to domestic water.
