摘要
饮用水中硝酸盐氮的污染问题日趋严重 ,对人类的健康有多方面的危害。离子交换、反渗透、电渗、生物反硝化、化学和化学催化反硝化都可从水中脱除硝酸盐 ,但目前投入实用的只有离子交换、生物反硝化、反渗透三种工艺。这些脱硝方法各有优缺点。本文综述了饮用水脱硝的应用与研究的现状 ,并对其发展的趋势进行了简单的论述。
The pollution of nitrate in drinking water has been serious and will be develop continuously in future. Nitrate in drinking water is dangerous to people in several aspects. Several treatments including ion exchange, biological denitrification, reverse osmosis, electrodialysis, chemical and catalytic denitrification can remove nitrate from water with varying degree efficiency. However, only processes of ion exchange, biological denitrification and reverse osmosis have realized business usage, and there are some limitations in these processes. This paper reviews the developments in the field of nitrate removal in drinking water.
