摘　　要：采用多段AO+MBR工艺对中国北方寒区城市某污水厂出水TN波动大、尾水外排容量低等问题进行提标改造。多段AO可以实现TN的高效去除,而MBR+臭氧催化氧化则可以实现COD、NH_(3)-N的有效控制,从而达到稳定出水的目的。提标改造后实际运行数据表明:出水COD和NH_(3)-N、TN、TP、SS检测均值分别为26.60 mg/L和0.29、7.59、0.38、5.32 mg/L,均达到《城镇污水处理厂污染物排放标准(GB 18918-2002)》中的一级A标准,其中NH_(3)-N达到《地表水环境质量标准》(GB 3838-2002)中的Ⅲ类水标准(ρ(NH_(3)-N)≤1.0 mg/L),TN稳定优于《城镇污水处理厂污染物排放标准(GB 18918-2002)》中的一级A标准(ρ(TN)≤15 mg/L)。The multi-stage AO+MBR process was used to upgrade the problems of effluent TN fluctuation and low discharge capacity of tailwater in a wastewater treatment plant in cold area of north China.Multi-stage AO can achieve efficient removal of TN,and MBR+ozone catalytic oxidation can achieve effective control of COD and NH_(3)-N,so as to achieve the purpose of stable effluent.After the upgrading reconstruction the actual operating data show that:The mean values of NH_(3)-N,TN,COD,TP and SS in effluent were 0.29 mg/L,7.59 mg/L,26.60 mg/L,0.38 mg/L and 5.32 mg/L,respectively.All of them meet the Class A standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002),among which NH_(3)-N meets the Class III water standard in the Environmental Quality Standard for Surface Water(GB3838-2002)(ρ(NH_(3)-N)≤1.0 mg/L).TN stability is better than the Class A standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002)(ρ(TN)≤15 mg/L).
