| 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．

| Abstract: | 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 mi- crobe and reduction of trihalomathanes(THMs)are investigated.It is found that pollutant removal can be ef- fectively 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% respective- ly,and index of A_(UV254) removal rate of settled water is raised by 6% and THMs production of filtered water is reduced by 92%,by addingρ(PPC)=1.0mg/L.The inactivity efficacy of pathogenic microbes is clearly improved,too.Experimental basis is provided for treatment of micropolluted raw water by this study. |
