摘　　要：针对武汉市城市污水的水质特点,采用一体式生物反应器(CIBR)与波形潜流人工湿地的组合工艺对其进行处理。研究表明,通过调整CIBR的运行工况来合理分配处理负荷,能有效降低季节性水质变化与湿地单元处理能力变化对出水水质的影响;当组合工艺的直接处理电耗平均值为0.19(kW.h)/m3时,出水COD、NH3-N、TN及TP平均值分别为15.68、3.25、8.69和0.50 mg/L,总体上达到了《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准。组合工艺的总能耗为0.22(kW.h)/m3,相比于A2/O及Bardenpho工艺,其处理能耗分别降低了20.77%和40.12%,节能效果显著。Based on the municipal wastewater characteristics in Wuhan City, the combined process of continuous-flow integrated biological reactor （CIBR） and wavy subsurface-flow constructed wetland was used to treat the municipal wastewater. The research shows that the influence of seasonal change in water quality and the change of the wetland treatment ability on the effluent quality can be effectively reduced by adjusting the operating condition of CIBR to distribute the pollutant load suitably. When the average energy consumption of the combined process is 0.19 （kW· h）/m^3, the average effluent concentrations of COD, NH3 - N, TN and TP are 15.68 mg/L, 3.25 mg/L, 8.69 mg/L and 0.50 mg/L, respectively, reaching the class I -A criteria specified in Discharge Standards of Pollutants for Municipal Wastewater Treatment Plants （GB 18918 -2002）. The total energy consumption of the combined process is 0.22 （kW · h）/m^3. The treatment energy consumption can be saved by 20.77% and 40.12% respectively compared with A2/O process and Bardenpho process.
