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 problem of nitrate nitrogen pollution in drinking water is becoming more and more serious, which has many hazards to human health. Ion exchange, reverse osmosis, electroosmosis, biological denitrification, chemical and chemical denitrification can remove nitrate from the water, but currently put into practical only ion exchange, biological denitrification, reverse osmosis three processes. These denitrification methods have their own advantages and disadvantages. This article reviews the current status of the application and research of drinking water denitrification, and briefly discusses its development trend.
