摘　　要：介绍了针对高氨氮、高有机物污染的上海淀浦河原水进行的高锰酸钾、高锰酸钾复合盐(PPC)预氧化研究。比较了它们的助凝、除锰、UV254和耗氧量的去除等效果;分析了它们的最佳投加量;指出了高锰酸钾及其复合盐对UV254和耗氧量没有明显的去除效果,两者均会增加出水色度。在综合考虑了处理效果与助凝剂使用成本的基础上得出:试验期间的上海淀浦河原水更适合采用高锰酸钾预氧化技术。Focusing on study of treatment of raw water of Shanghai Dingpu River polluted by high content of ammonia nitrogen and organic substances with permanganate and permanganate pre-oxidation,the results of aided-flocculation,removal of manganese and UV 254 as well as oxide consumption are compared.Their best dosages are determined.Test shows that effects of permanganate and complex salt on removal of UV254 and oxide consumption are of no significance;instead both would raise water colourity.Considering comprehensively result of water treatment and cost of flocculent,the paper concludes that permanganate pre-oxidation technology is more suitable for the treatment of raw water of Dingpu River.
