摘要该文从分子量转化的角度对水体中有机物在水处理工艺过程中的转化进行了研究。针对特定的水质特征(小分子有机
物居多),比较了 3 种不同的氧化剂(臭氧、氯和高锰酸钾)对有机物分子量(molecular weight, MW)的转化情况。试验证实臭氧氧
化可明显减少 MW>30 kDa 的有机物含量,进一步通过絮凝沉淀和过滤工艺可使 MW>30 kDa 的有机物被有效去除;活性碳过
滤后的水样中 MW>10 kDa 的有机物更容易生成三卤甲烷(THMs)类的消毒副产物,而 MW<1 kDa 的有机物则更加容易生成卤
乙酸(HAAs)。该研究从分子量分布的角度证实了常规水处理工艺与深度处理工艺的互补性,并探讨了分子量、溶解性有机碳
(DOC)与消毒副产物前体物(DBPFP)之间的内在关系。

Abstract The change of anic matter molecular weight(MW)in the Huangpu River raw water during water treatment was ex-
plored in this paper. Three kinds of oxidations such as oxidants-ozone, chlorine and potassium permanganate were used pare
the change of the position first. The results show anic matters with MW >30 kDa can be decreased by ozonation, and
