典型含氮消毒副产物的形成及去除的研究进展

水的消毒处理会导致大量副产物的产生,其中以卤代乙睛、亚硝胺及卤代硝基甲烷三种物质为代表的含氮消毒副产物(N-DBPs)具有强烈的致毒致癌性,成为当今一大研究热点。文章结合历年国内外学者对N-DBPs的研究成果,总结了三种典型N-DBPs的分析方法,并对其形成机制和去除途径进行了综述。在此基础上,文章展望了今后有关N-DBPs的研究思路及方向,对深入研究N-DBPs具有一定的参考意义。

Formation and Removal of Typical N-DBPs-A Review

When the wastewater is disinfected, many byproducts will be formed. N-DBPs including HANs, nitrosamines and HNMs mainly, are very high in mutagenicity and carcinogenicity. and become one big focus. The analysis method,formation and removal approaches of the N-DBPs were summarized broadly on the basis of most of the researches in recent years. Finally, the ways of research about N-DBPs in the future were proposed, which made some sense to the further research of N-DBPs to some extent.
