摘    要:含氮消毒副产物(N-DBPs)具有很高的生物毒性和致癌性,近年来受到广泛关注。本文对目前N-DBPs的研究进展进行了概述,重点总结了典型N-DBPs包括卤乙腈(HANs)、卤代硝基甲烷(HNMs)、卤代乙酰胺(HAcAms)和亚硝胺(NAs)的生成机制;并归纳了N-DBPs的毒性效应和毒性机制。根据N-DBPs的生成途径,应该重点控制水中含胺类氮源前体物,并优化设计消毒剂种类和投加方式,在控制病原体的前提下,尽量削减高毒性N-DBPs的生成。本研究旨在为控制消毒副产物生成、提高饮用水水质提供理论参考。

关 键 词:含氮消毒副产物  饮用水  毒性作用  生成机制

Abstract:Nitrogenous disinfection byproducts (N-DBPs) have received attention in recent years because of high biological toxicity and carcinogenicity. In this paper, the research progress on N-DBPs is summarized, emphatically formation mechanism and the toxicity effects of the typical N-DBPs, including haloacetonitriles (HANs), halonitromethanes (HNMs), haloacetamides (HAcAms) and N-nitrosamines (NAs). Based on the formation pathways and toxicological effects, amine-containing precursors should be reduced before disinfection and the design of disinfection systems should be optimized to minimize N-DBPs formation and meet the pathogen reduction goals. This review paper provides information for reducing the generation of disinfection by-products and improving drinking water quality.
Keywords:nitrogenous disinfection byproducts   drinking water   toxicological effect   formation mechanism
