Eight typical drinking water supplies in China were selected in this study. Both source and tap water were used to investigate the occurrence of chlorinated disinfection byproducts (DBPs), and seasonal variation in the concentrations of trihalomethanes (THMs) of seven water sources was compared. The results showed that the pollution level for source water in China, as shown by DBP formation potential, was low. The most encountered DBPs were chloroform, dichloroacetic acid, trichloroacetic acid, and chlorodibromoacetic acid. The concentration of every THMs and haloacetic acid (HAA) compound was under the limit of standards for drinking water quality. The highest total THMs concentrations were detected in spring.
本研究选取了中国 8 种典型饮用水水源，分别采用源水和末梢水为研究对象，调查水中氯化消毒副产物（DBPs）的生成情况，并对 7 种水源水中三卤甲烷（THMs）浓度的季节性变化进行了比较。结果表明，中国水源水的污染程度（以 DBP 生成潜能来表示）较低。所检测到的 DBPs 主要为氯仿、二氯乙酸、三氯乙酸和一溴二氯乙酸。各种 THMs 和卤乙酸（HAA）化合物的浓度均低于饮用水水质标准限值。总三卤甲烷浓度最高的是春季。
