摘要
选择有代表性的芳香类有机物,在含有腐殖酸的水溶液中进行氯化试验,测定三卤甲烷和卤乙酸的生成特性,并分析有机物的化学结构对生成消毒副产物的影响。结果表明,各受试物氯化生成消毒副产物的活性和反应速率排序为间苯二酚>对苯二酚>邻苯二酚>苯酚>苯胺>苯甲酸>硝基苯;芳香类有机物苯环上官能团的性质、数量和位置等影响消毒副产物的生成;间苯二酚的氯化反应可分为快速反应阶段和慢速反应阶段。
Some representative aromatic organic compounds and humic acid, which are often present in source water, were selected to conduct chlorination test. We have determined the formation characteristics of trihalomethanes and haloacetic acids, and analyzed the impact of chemical structure of organic compounds on the disinfection byproducts （DBPs） formation. The results indicated that： （1） The orders of DBPs formation activity and reaction rate in the chlorination reactions of the compounds were 1,3-benzenediol〉 1,4-benzenediol〉 1,2-benzenedioE〉 phenol〉aniline.benzoic acid〉 nitrobenzene; （2） The characteristics, number and location of functional groups on the benzene ring affected the DBPs formation; （3） The chlorination reaction of 1,3-benzenediol included rapid and slow reaction stages.
