摘　　要：在泄洪时的东江水源水中加入腐殖酸以模拟水源有机物污染,采用连续流动态试验考察常规混凝沉淀、强化混凝沉淀、预氧化-混凝沉淀、粉末活性炭吸附-混凝沉淀工艺以及预氧化与粉末活性炭联用-混凝沉淀工艺对有机物的去除效果。结果表明,高锰酸钾和粉末炭联用-混凝沉淀工艺能有效提高常规混凝沉淀工艺对有机物的去除效果。在不改变水厂现行处理工艺的基础上,该技术可以快速、有效地应对水源水有机物污染。The present paper takes it as its target to introduce a new approach of the author to treating the organic matters by combining pre-oxidation and activated powdered carbon in the raw water in Guangdong, China south. As is known, Dongjiang River （the East River） is the main drinking water source for the residents of Dong- guan City. During the flood season, it is necessary for Dong-yin canal to open its sluice gate to discharge the flood water for the safety of the city. In that case, large quantities of waste water are to be discharged into the East River and in turn cause serious pollution of organic mat- ters. Such a kind of serious water pollution can not be solved by using the traditional coagulation and sedimentation processes. And in that case, four methods are used to remove the organic waste in the wa- ter, namely, the routine coagulation sedimentation process, the en- hanced coagulation sedimentation process, the pre-oxidation coagula- tion sedimentation process, and the combined method of the powdered activated carbon pre-adsorption coagulation sedimentaq＇on process and pre-oxidation and powdered activated carbon pre-adsorption combina- tion coagulation sedimentation process. Yet, the results and the ef- fects remain far from being satisfactory. With the problem in mind, we have investigated the actual situation of the pollution by using the flood water of the river with humic acid. Continuous dynamic test re- suits demonstrate that： the removal rate can reach UV254, TOC was 34.4%, 57.8% when the dose of the coagulant used was 40 mg/L in the enhanced coagulation process. And, from the point of remov-ing effect, it can be said that the organic matter removal rate of coal activated carbon is better than the wood charcoal and coconut shell charcoal in pre-adsorption coagulation sedimentation process. The re- moval rate of UV254 can be made to rise from 55 % to 69.7 % when the coal activated carbon dosage is increased from 5 mg/L to 30 mg/L. When the pre-oxidation coagulation sedimentation process i
