饮用水处理消毒副产物产生及控制研究进展

Advances in Research on Production and Control of Disinfection by-Products in Drinking Water Treatment

城市给水消毒是改善水质、提高居民饮用水安全的重要举措,是给水工艺中必不可少的环节。但是,消毒过程中会产生饮用水消毒副产物,它是天然水体中含有的微量有机物与消毒剂发生反应而生成的物质。人饮用含有消毒副产物的水后,人体健康会受到影响,必须对其加以控制。本文介绍了目前城市给水中常见的几种消毒措施以及相关消毒副产物,讨论了相关控制技术并展望了今后的研究方向。

Municipal water supply disinfection is an important measure to improve water quality and improve the safety of drinking water for residents. It is an indispensable link in the water supply process. However,during the disinfection process,drinking water disinfection by-products are produced,which are substances formed by the reaction of trace organic substances contained in natural water bodies with disinfectants. After drinking water containing disinfection by-products,human health is affected and must be controlled. This paper introduces several common disinfection measures and related disinfection by-products in urban water supply,discusses related control technologies and looks forward to future research directions.
