The quality of the effluent water was stable and good. During stable operation,the COD,NH3-N and TP concentrations of the influent water were 147-475,42-23. 5 and 0. 65-0. 85 mg/L,respectively,and those of the effluent water were 147-475,0. 08-0. 82 and 0. 18-0. 26 mg/L,respectively,so the average removal rates of COD,NH3-N and TP were 82%,97% and 72%,respectively,meeting the standard for Class-A emissions of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant( GB18918-2002). In addition,the process has certain anti-impact capacity and ability to mitigate membrane fouling,meeting the objectives of upgrading and transformation. This study will provide reference for upgrading of existing sewage treatment plants.展开更多
