饮用水源的复合污染及其健康风险控制是当前饮用水水质净化面临的重要难题，其中饮用水消毒副产物（DBPs）的控制为重中之重。作为DBPs的主要前驱物质，水源中天然有机物（NOM）和溴/碘化物的复合污染及其产生的潜在健康危害十分显著。本项目拟以NOM-溴/碘化物复合污染体系为研究对象，以生物毒性效应为评价依据，采用磁性树脂吸附与混凝的处理方法，首先阐明磁性树脂吸附与混凝对溴、碘化物的净化效能与机制，在此基础上，揭示磁性树脂吸附与混凝降低NOM-溴/碘化物复合污染的界面作用机制以及对DBP生成势（DBPFP）和生物毒性效应的削减能力；探讨磁性树脂吸附与混凝耦合降低复合污染的耦合方式和关键技术参数，揭示耦合工艺对DBPFP控制和生物毒性削减能力的优化调控方法，提出基于磁性树脂吸附与混凝联用的NOM-溴/碘化物复合污染及其健康风险的控制策略。

The control of complex pollution and its health risk is the difficult issue of drinking water treatment. In purticular, disinfection by-products (DBPs) control in drinking water would be our priority. The complex pollution and potential health hazard of natural organic matters (NOM) and bromide/iodide (Br/I), the important DBPs precursors, in source water are notable. This study will take the complex pollution mixture of NOM-Br/I as object, the biological toxicity as water quality evaluation method and magnetic resin adsorption and coagualtion as treatment techniques. The purification efficiency and mechanism of Br/I by magnetic resin adsorption and coagulation will be firstly investigated. Then the interface interaction mechanism and the efficiency of magnetic resin adsorption and coagulation in controlling the complex pollution mixture, DBP formation potential (DBPFP) and biological toxicity will be disclosed. The combination manners of adsorption and coagualtion and their key technical parameters will be systematically optimized to decrease the complex pollution, DBPFP and its biological toxicity. The control strategy of the complex pollution of NOM-Br/I and its potential health risk will be provided basing on the combination of magnetic resin adsorption and coagualtion.
