摘要:

某城市污水处置厂一期设想范围为2×10^{4m3/d,采取保守A2/O工艺,出水水质很难到达《城镇污水处置厂污染物排放尺度》(GB 18918—2002)一级A尺度。二期扩建项目设想范围为3×104m3/d,在总结一期项目运转经验根本上,提出颠倒A2/O+A/O工艺,并辅以化学除磷和接触过滤等深度净化处置工艺,确保出水不变达标排放。二期扩建项目投入运营后,出水COD、SS、氨氮、TP平均浓度别离为34.5、7.8、3.8、0.34 mg/L,不变到达一级A排放尺度。}

Abstract:

The first-phase design capacity of a wastewater treatment plant was 2×10^{4m3/d. 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.}
