摘　　要：传统氯消毒工艺因易生成对人体有害的消毒副产物被广泛关注，采用替代氯消毒工艺控制消毒副产物是目前的研究重点。该文以天津市某自来水厂滤后水为试验对象，采用二氧化氯一氯胺顺序投加联合消毒工艺，分析了不同投加量组合对消毒副产物（THMs，HAAs和亚氯酸盐）产量的控制情况。结果表明当二氧化氯投加量为0．10—0．50mg／L、氯胺投加量为0．50～1．50mg／L时，消毒副产物的生成量均能得到有效控制，符合相关标准的要求。Traditional chlorine disinfection process has attracted wide attention because of its harmful disinfection byproducts. The control of disinfection byproducts in drinking water by sequential dosing of joint disinfectants with dioxide and chloramine was investigated in this study. The raw water was taken from filtration water in a waterworks in Tianjin, which was disinfected by the different doses combination of chlorine dioxide and chloramine. The results show that when dosage of chlorine dioxide is 0. 10 0.50 mg/L and chloramine is 0.50 ~ 1.50 mg/L, the generation of disinfection byproducts can be effectively controlled, which meets the requirements of relevant standards.
