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。
NDMA (dimethylnitrosamine) is a newly detected strong carcinogenic pollutant in surface water and disinfectant drinking water. It is of great practical significance to study its removal method for the protection of public health and the development of safe water industry. In this paper, the removal methods of NDMA were summarized. The advantages and disadvantages of volatilization, stripping, adsorption, reverse osmosis, biological treatment, metal reduction, UV treatment, natural photolysis and titanium dioxide photocatalysis were reviewed. The research directions in this field were also discussed Aiming to provide new ideas for developing efficient and practical methods and approaches to solve the problem of nitrosamines pollution in surface water and drinking water.
