本文介绍了美国自来水厂服务公司系统处理厂和配水系统中消毒副产物（DBPs）和控制措施的分析调查结果。这项调查分三个阶段进行，涉及24家美国系统处理厂。本文具体讨论了DBP控制选项，包括:优化混凝以去除总有机碳/延迟氯化；使用氯胺作为后消毒剂；通过GAC过滤去除DBP。凝血研究的结果表明，为控制某些DBP而优化的处理会促进其他DBP的形成。这种悖论可能导致DBP的厂内控制无效。氯胺评价表明，氯胺能有效地控制成品水中的DBPs。评估了GAC过滤去除有机碳、三卤甲烷、卤代乙腈、卤代酮、卤代乙酸、水合氯醛、氯化苦和2,4,6的能力- TCP。

This paper presents results of an analytical survey of disinfection byproducts (DBPs) and control measures in American Water Works Service Company system treatment plants and distribution systems. The survey is a three-phase effort involving 24 American System treatment plants. This paper specifically addresses DBP control options, including: coagulation optimized for total organic carbon removal/delayed chlorination; use of chloramines as a post-disinfectant; and DBP removal by GAC filtration. The results of the coagulation study indicate that treatment that is optimized to control certain DBPs enhances the formation of others. This paradox could render in-plant control of DBPs ineffective. The chloramine evaluation indicates that chloramines effectively control DBPs in finished water. GAC filtration was evaluated for its ability to remove organic carbon, trihalomethanes, haloacetonitriles, haloketones, haloacetic acids, chloral hydrate, chloropicrin, and 2,4,6-TCP.
