饮用水中消毒副产物前体物的控制技术研究现状

Current Study on Control Technology of Disinfetion By-product Precursor in Drinking Water

阐述了饮用水中消毒副产物前体物主要来自于原水中的腐殖质,如腐殖酸和富里酸等天然有机物。介绍了不同特征的有机物与氯反应生成消毒副产物的关系,着重介绍了化学预氧化,活性炭吸附和组合工艺等去除消毒副产物前体物技术的应用现状,简述了关于饮用水中消毒副产物前体物的控制技术研究的发展趋势。

This paper mainly describes the precursor of disinfection by-products in drinking water mainly come from the natural organic matter in raw water,such as humic acid and fulvic acid in humus.And it introduced the relationship between several different types of organic reaction and chlorine produce disinfection by-products,emphasizing the application status of removal of disinfection by-product of precursor technology,such as chemical preoxidation,activated carbon absorption and combined process etc.At last,it summarizes the development trend of precursor of disinfection by-products control techniques in drinking water.
