With the traditional A2/O process, the effluent quality was very difficult to meet the first class A criteria specified in theDischarge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002). The design capacity of second-phase extension project was 3 104m3/d, on the basis of operation experience of the first-phase project, the combination process of reversed A2/O+AO followed by the advanced treatment process of chemical phosphorous removal and contact filtration were adopted in ensure the stable effluent quality. After second-phase extension project was put into operation, the effluent concentrations of COD, SS, ammonia nitrogen, TP were 34.5 mg/L, 7.8 mg/L, 3.8 mg/L, 0.34 mg/L, respectively, and all effluent indexes could meet the first level A criteria.
