摘　　要：以天津市生活饮用水为对象，分别实验研究对比了单独高锰酸钾预氧化、高锰酸钾预氧化．强化混凝对饮用水浊度、有机物及DBPs产生量的影响。结果表明，与传统预氯化相比：高锰酸钾预氧化，UV254和DOC去除率分别在7．0％～10．35％和7．8％～10．4％之间，THMs和HAAs减少率分别在30％～33％和19％～22％之间。高锰酸钾预氧化一强化混凝，DOC和UV254去除效率分别是40．5％和63．3％，出水THMs和HAAs分别47．8、76．8μg/L，减少率分别达到61．3％、50．2％。高锰酸钾预氧化－强化混凝可达到减少消毒副产物DBPs的产生以及去浊的目的。To study the effect of potassium permanganate pre-oxidation process on the control of drinking water disinfection by-products, the effect of different pre-oxidation process on control the concentration of DBPs and the effect of chitosan coagulant on turbidity removal were investigated here. The static trial show that compared with the traditional prechlorination, the removal efficiency of UV254 and DOC during potassium permanganate pre-oxidation process is between 7.0%-10.35% and 7.8%- 10.4%. THMs and HAAs are 30%-33% and 19%-22%. During potassium permanganate and enhanced coagulation combined process, removal efficiency of DOC, UV254 THMs and HAAs are 40.5%, 63.3%, 61.3% and 50.2%. Potassium permanganate pre-oxidation and enhanced coagulation combined is an effective technology in drinking water treatment methods.
