摘　　要：通过动态连续流实验考察了高锰酸盐预氧化与生物活性炭-砂滤池工艺对THMFP 的去除效果。研究发现,高锰酸盐预氧化能够提高混凝工艺对大分子有机物(MV>5100)的去除效能,生物活性炭-砂滤池对小分子有机物(MV<1200)有明显的去除作用,该组合工艺对不同分子量有机物的去除具有很好的互补性。与常规处理工艺相比,该组合工艺对THMFP的去除率提高了44％。A novel combined process of permanganate composite chemical （PPC） preoxidation and BAC - sand filter was studied to remove THMFP by continuous flowing experiments. The result shows that coagulation with PPC preoxidation is very effective in removing the organics with molecular weight（MW） higher than 5100 and BAC - sand filter is efficient in removal of the organics with MW lower than 1200. The coagulation with PPC preoxidation and BAC - sand filter are mutually complementary to remove the organics with different MW. The removal rate of THMFP in the combined process is 44% higher than that in conventional water treatment.
