摘　　要：饮用水消毒可以有效除去病毒、细菌等有害微生物,但消毒剂会与水中的有机物反应生成多种消毒副产物(DBPs),危害人类健康。基于对消毒副产物种类、生成及污染现状的探讨,归纳总结了DBPs的典型生物毒性及其毒性作用机制。为有效防控DBPs环境风险,深入探讨了针对去除DBPs前体物、优化消毒剂及消毒过程、DBPs毒性的调控策略。最后对DBPs生物毒性作用机制及调控策略的研究进行了展望,为DBPs污染防治提供理论与技术支持。Drinking water disinfection could effectively remove harmful microorganisms（e. g. viruses and germs）,but disinfectors can react with organic substances in water and form many kinds of disinfection by-products（DBPS）,to harm human health. The typical biological toxicity of DBPs and its toxic effect mechanism are concluded and summarized,based on the discussion on the variety,formation and pollution status of DBPs. To prevent and control the environmental risks of DBPs effectively,the control strategies aiming at the removal of DBPs precursor,the optimization of disinfectors and disinfection process,and the toxicity of DBPs are discussed in depth. At the end,the research on DBPs biological toxic effect mechanism and control strategies are looked ahead,providing theoretical and technical supports to the prevention and control of DBPs pollution.
