中文摘要：

NDMA（二甲基亚硝胺）是在地表水和消毒后的饮用水中新检测到的强致癌污染物,研究其去除方法对保护公众健康和发展安全的水工业具有重要的现实意义。本文综述了NDMA的去除方法,分析了挥发﹑汽提﹑吸附﹑反渗透﹑生物处理﹑金属催化还原﹑UV处理﹑自然光解和二氧化钛光催化方法的优、缺点,并探讨了该领域的研究方向,旨在为解决地表水和饮用水中的亚硝胺污染问题开发高效、实用的方法和途径提供新的思路。

英文摘要：

NDMA（N-nitrosodimethylamine） is an extremely potent carcinogen detected recently in surface water and drinking water disinfected by chlorine and chloramines,and its removal research would exert important impact on protecting the public health and promoting the safety of water industry.The progress of the removal technologies of NDMA,which included volatilization,air stripping,adsorption,reverse osmosis,biodegradation,metal-catalyzed reduction,UV treatment,photolysis and TiO2-mediated photocatalytic degradation was summarized in this paper.It concluded current bottleneck in the research fields and showed a bright prospect of these techniques,thus providing new ideas for further development of highly-efficient and practical approaches to resolve the contamination problems caused by N-nitrosamines in surface and drinking water.
