摘　　要：针对微污染水,就高锰酸钾预氧化技术与与饮用水常规混凝沉淀工艺组合联用开展了一些试验研究。结果表明:高锰酸钾的预氧化作用有助于PAC混凝沉淀工艺对原水中有机污染物的去除;KMnO4和聚合氯化铝(PAC)的投加方式对原水耗氧量的去除率有明显影响;KMnO4预氧化有一个最佳时间;高锰酸钾预氧化-混凝沉淀组合微污染水处理工艺,对原水pH值的波动有比较好的适应性。In this paper,some test research for combination process of KMnO4 pre-oxidation-coagulative precipitation in slightly polluted water treatment were studied.The results showed that KMnO4 pre-oxidation is helpful to the removal of trace organic pollutants for PAC coagulative precipitation technology in slightly polluted water treatment;the adding means of KMnO4 and PAC has important influence on the removal of CODMn in micro-polluted raw water;the pre-oxidation of KMnO4 has an optimal time window;it has better pH adaptability of raw water for the combination process of KMnO4 pre-oxidation-coagulative precipitation in slightly polluted water treatment.
