- Abstract:
- In order to cooperate with the ecological management of Yitong River, a wastewater treatment plant (WWTP) in Changchun was upgraded and reconstructed, and the treatment capacity of the upgrading project was 68×104 m3/d. In view of the characteristics such as poor biodegradability of influent, high standard of effluent, shortage of available land and maximum use of the original structures and equipments of the WWTP, the combined process of integrated fixedfilm activated sludge (IFAS) transformed from the original biochemical tank, the submerged ultrafiltration membrane process (SUF) and ozone contact oxidation was determined to further remove the COD, BOD5, SS, NH3-N, TP and chroma. After upgrading, the effluent reaches the level B criteria in Discharge Standard of Water Pollutants for Municipal Wastewater Treatment Plants (DB 11/890-2012). The process flow, main design parameters, equipment configuration and occupied area of each process were introduced. The design, operation mode, investment and treatment cost of the SUF were introduced emphatically.
