摘　　要：采用微滤—活性炭过滤—微滤—反渗透(MCM/RO)工艺对污水处理厂的二沉池出水进行深度处理,考察了该工艺的处理效果。结果表明,该工艺对浊度、CODMn、TOC、UV254、细菌和总大肠菌群均有良好的去除效果,上述各指标的出水平均值分别为0.095NTU、2.57mg/L、0.84mg/L、0.013cm-1、16个/L和11个/L。RO膜对砷、镉、铅的截留效果良好,平均去除率分别为90.5%、99%和98%。The microfiltration/activated carbon/microfiltration/reverse osmosis （MCM-RO） process was applied for advanced treatment of the effluent from secondary sedimentation tank of a wastewater treatment plant. The treatment effect of this process was investigated. The results show that the removal efficiencies of turbidity, CODMn, TOC, UV254, bacteria and coliform are better, and the average values of them in the effluent are 0. 095 NTU, 2.57 mg/L, 0.84mg/L, 0. 013 cm^-1 , 16 unit/L and 11 unit/L respectively. Reverse osmosis membrane can reject As, Cd and Pb effectively, and the average removal rates are 90.5% , 99% and 98% respectively.
