摘要
The invention, belonging to the technical field of wastewater biological treatment, discloses a method of upgrading the activated sludge process based on functional suspended carriers in the wastewater biological treatment process. The reaction zone of the original activated sludge process is divided into an aerobic zone, anoxic zone, aerobic zone 1 and aerobic zone 2 without increasing the footprint and extending the original process. A certain amount of functional suspended carriers is added in each reactor according to the treatment requirements, and influent diversion is used, in order to improve the pollutant removal performance of the modification process. Furthermore, the effluent quality can meet the requirements of discharge standards. This method is especially suitable for the upgrading of built wastewater treatment plants.
