摘要:
某城市污水处理厂一期设计规模为2×104 m3/d,采用传统A2/O工艺,出水水质很难达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A标准。二期扩建工程设计规模为3×104 m3/d,在总结一期工程运行经验基础上,提出倒置A2/O+A/O工艺,并辅以化学除磷及接触过滤等深度净化处理工艺,确保出水稳定达标排放。二期扩建工程投入运营后,出水COD、SS、氨氮、TP平均浓度分别为34.5、7.8、3.8、0.34 mg/L,稳定达到一级A排放标准。
Abstract:
The first-phase design capacity of a wastewater treatment plant was 2×104 m3/d. With the traditional A2/O process, the effluent quality was very difficult to meet the first class A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002). The design capacity of second-phase extension project was 3×104 m3/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.
