饮用水消毒副产物的控制工艺研究

Control Process of Disinfection By-products in Drinking Water

为了预防通过饮用水途径传播的传染病,消毒已经成为水处理工艺中不可或缺的步骤。然而,消毒工艺在杀灭微生物的同时,也会产生消毒副产物(DBPs)。消毒副产物因其具有致癌、致畸和致突变的三致特性而在全球范围内备受关注。本文聚焦于消毒副产物的生成条件与危害两方面,考察了饮用水中消毒副产物的控制方法,并对现阶段消毒副产物研究方法中存在的问题与不足进行分析。最后针对消毒副产物未来的控制策略提出展望。

In order to prevent the transmission of infectious diseases through the drinking water route,disinfection has become an essential part of the water treatment process.But disinfection process in killing microorganisms at the same time,will also produce disinfection by-products(DBPs).Disinfection by-products have attracted worldwide attention because of their carcinogenic,teratogenic and mutagenic characteristics.In this paper,focusing on the formation conditions and hazards of disinfection by-products,the control methods of disinfection by-products in drinking water were investigated,and the problems and shortcomings in the control methods of disinfection by-products at present were analyzed.Finally,the future control strategy of disinfection by-products was prospected.
