再生水消毒副产物的检测、生成与控制

在水资源紧缺的当下，污水再生利用是一项重要的环保战略更是资源战略.消毒能有效杀灭病菌和阻断介水疾病的传播，是保障再生水用水安全的重要手段.然而，消毒剂会不可避免地与水中有机物发生反应形成具有毒害效应的消毒副产物.围绕污水在再生消毒过程中所产生的消毒副产物，针对其检测识别方法、生成条件（前体物、消毒工艺及水质条件对消毒副产物生成的影响）以及控制方法（源头控制、过程控制及末端控制）进行综述.在此基础上，对再生水消毒副产物的未来研究动态进行了探讨，可为保障再生水的安全利用提供依据.

Detection, Generation, and Control of Disinfection By-products of Reclaimed Water

At the time when water resources are in short supply,wastewater recycling is both an important environmental protection strategy and also a resource strategy. Disinfection is essential to ensure the biological safety of reclaimed wastewater by killing pathogens and preventing the spread of waterborne diseases. However,the disinfection process could inevitably produce toxic disinfection byproducts(DBPs)due to the reaction between the disinfectants and wastewater organic matters. Regarding wastewater DBPs,this study reviewed their identification methods,formation conditions(including precursors,the effect of water quality,disinfectants,and operational parameters on DBPs),and control methods(including source control,process control,and end control). In addition,future research trends of wastewater DBPs were discussed.
