摘　　要：针对某市微污染水源水的水质特点,通过小试考察了高锰酸盐复合剂(PPC)与NH_2Cl联合预氧化工艺在助凝、助滤、去除有机物、灭活致病微生物及减少三卤甲烷(THMs)等方面的效能．结果表明,PPC与NH_2Cl联用能明显地强化除污染效果,与单独NH_2Cl工艺相比,投加ρ=1．0 mg/L的PPC可使沉后和滤后水浊度去除率分别提高3个和1个百分点；使沉后水254 nm波长时的紫外吸光度去除率提高6个百分点；使滤后水THMs的生成量降低92%；并明显提高对致病微生物的灭活效能．为微污染水源水的处理提供了试验依据．The combined pre-oxidation process with potassium permanganate composite （PPC） and chloramine is studied on a laboratory scale, in accordance With water quality characteristics of polluted raw water in the A city. The effects of coagulation aid, filtration aid, removal of organic matter, inactivation of pathogenic microbe and reduction of trihalomathanes （THMs） are investigated. It is found that pollutant removal can he effectively enhanced by the combined applications of PPC and chloramine, compared with individual application of chloramine. Turbidity removal rate of settled water and filtered water are raised by 3 % and 1% respectively, and index of Auv254 removal rate of settled water is raised by 6% and THMs production of filtered water is reduced by 92 %, by adding ρ（PPC） = 1.0 mg/L. The inactivity efficacy of pathogenic microbes is clearly improved, too. Experimental basis is provided for treatment of micropolluted raw water by this study.
