摘要
硝酸盐氮是地下水中的主要污染物之一,目前硝酸盐氮的去除方法可以分为物理法、化学法、生物法及多种方法组合运用。文章首先分析了硝酸盐氮污染的来源,然后分别对各种硝酸盐氮去除方法的原理做了简要阐述并分析了各种方法的特点,以期为硝酸盐氮去除工艺的选择提供参考。
Nitrate nitrogen is one of the main pollutants in groundwater. At present, nitrate nitrogen removal methods can be divided into physical method, chemical method, biological method and a combination of various methods. This paper first analyzes the sources of nitrate nitrogen pollution,and then briefly expounds the principles of various nitrate nitrogen removal methods and analyzes the characteristics of each method, so as to provide references for the selection of nitrate nitrogen removal process.
