摘要
水体中腐殖质是消毒过程中产生三氯甲烷类(THMs)物质的前体,其中腐植酸和富里酸又是水体腐殖质的主要组成部分。本文阐述了水体腐殖质的形成与基本性质,分析了由其引起的危害,并结合国内外目前对水体腐殖质去除的研究现状,评述了水体腐殖质的主要去除技术与方法。
Humics, mostly composed of humic acid and fulvic acid in water, is viewed as precursor of trihalomethane （THMs）during the disinfection. The generative process of aquatic humics is described as well as its basic characteristics and its potential risks are discussed in the paper. Based on current researches on aquatic humics removal, the removal technologies are assessed.
