摘　　要：以实验室模拟含嗅微污染水为研究对象,对比考察常规处理/浸没式超滤膜组合工艺(CUF)和常规处理-粉末炭/浸没式超滤膜组合工艺(CPUF)启动阶段的除污效能及膜污染状况。结果表明:两种组合工艺的除浊率均稳定在98%以上;CPUF工艺开始稳定去除NH+4-N的时间较CUF工艺缩短了7 d,且对UV254的去除率增加了16.3%,出水土臭素平均浓度为3.44 ng/L,远低于CUF工艺出水的18.99 ng/L。CPUF工艺能有效延缓膜污染,连续运行28 d后跨膜压差仅增长了1.49 kPa,较CUF工艺低1.78 kPa。The pollutants removal performance and membrane fouling of conventional treatment/ immersed uhrafiltration membrane process （CUF） and conventional treatment/powered activated carbon/ immersed uhrafihration process （CPUF） in start-up phase for treatment of simulated micro-olluted water containing taste and odor were investigated. The results indicated that the turbidity removal efficiencies by the two combined processes were above 98%. Compared to CUF process, the time to reach stable ammonia nitrogen removal by CPUF process was shortened by 7 d, and UV254 removal rate was improved by 16.3%. Moreover, the average geosmin （GSM） concentration in the effluent of CPUF process was only 3.44 ng/L, far less than that of CUF process （ 18.99 ng/L）. CPUF process could effectively alleviate membrane fouling, and the trans-membrane pressure increased only by 1.49 kPa in 28 d, which was 1.78 kPa lower than that of CUF process.
