Wastewater treatment technology has undergone hundreds of years of changes, from the initial primary treatment to the current tertiary treatment, from simple disinfection and precipitation to organic matter removal, nitrogen and phosphorus removal, and advanced treatment and reuse. The treatment process has also developed from traditional activated sludge process and oxidation ditch process to A/O, A2/O, AB, SBR (including CCAS process) and other processes to meet different effluent requirements. Sewage treatment methods can generally be classified into physical methods, chemical methods and biological methods.
