摘要 含氮消毒副产物作为一类具有强"三致"作用的高毒性新兴消毒副产物,其生成和控制等相关问题是饮用水处理领域研究的重点和难点。典型的含氮消毒副产物有卤乙腈、亚硝胺、卤代硝基甲烷及卤乙酰胺,在总结这类消毒副产物的生成机制和去除手段的基础上,针对其浓度低、极性强造成富集难、去除率低的瓶颈问题,分别从新材料、新技术研发及工艺优化组合方向提出了消除含氮消毒副产物问题的研究重点,展望了新型纳米功能材料耦合电化学技术处理含氮消毒副产物的发展前景,为解决强"三致"作用的高毒性新兴含氮消毒副产物问题提供参考。 Nitrogenous disinfection by-products(N-DBPs)are high-toxicity emerging disinfection by-products with intensive"carcinogenicity,teratogenicity,mutagenicity".Issues about their generation and control are research focus and difficulty in the drinking water treatment field.The typical nitrogenous disinfection byproducts include haloacetonitrile,nitrosamine,halogenated nitromethane,and halogenated acetamide.Based on the summary of generation mechanism and removal methods of these disinfection by-products,for the bottleneck problems of difficult enrichment and low removal efficiency due to their low concentration and strong polarity,the research focus on removal of nitrogenous disinfection by-products was proposed from the aspects of new materials,new technological development and process optimization combination,and the prospect of novel nanomaterials coupling electrochemical technology to treat nitrogenous disinfection byproducts was expected.This can provide reference for solving problems of high-toxicity emerging disinfection by-products with intensive"carcinogenicity,teratogenicity,mutagenicity".
