摘　　要：为了研究二氧化氯与氯联合消毒工艺过程中消毒副产物的形成规律以及特点,探讨二氧化氯对氯化消毒副产物的控制效果,对我国北方某市使用同一水源的4家水厂消毒工艺进行全面的采样与检测,并对各项消毒副产物检测结果进行了全面的分析.结果表明,二氧化氯与氯联合消毒比单纯液氯消毒形成的三卤甲烷平均降低74.39%,卤乙酸平均降低40.65%.在控制氯酸盐及亚氯酸盐生成方面,使用纯二氧化氯发生器生成的氯酸盐要显著低于化学法复合二氧化氯发生器.In an effect to explore the production mechanisms and characteristics of the by-products in different water disinfection processes,and to investigate the effect of chlorine dioxide on the formation of chlorine by-products,water samples from 4 water plants in a city in China were analyzed.Compared with the water disinfected with chlorine alone,the amount of THMs and HAAs decreased by 74.39% and 40.65%,respectively,in water samples disinfected with both chlorine dioxide and chlorine.Likewise,the amounts of chlorate and chlorite produced by the chlorine dioxide chemical generator was higher than that of the pure chlorine dioxide generator.
