摘要
地下水中硝酸盐氮的脱除可以采用传统脱除法和催化反硝化脱除法。介绍了地下水脱氮技术的发展历史,着重介绍了最新发展提出的催化反硝化脱氮法。具体阐述了催化反硝化脱氮的原理、处理效果、主要影响因素、优势和局限性,对目前存在的问题和今后的发展方向,指明催化活性和催化选择性的提高,是催化反硝化法实用化过程中需要解决的关键问题。
Nitrate in groundwater can be denitrificated by traditional removal and catalytic reduction. The development history as well as catalytic reduction including principle, treatment efficiency, impact factors and future prospective was introduced. Improvement of activity and selectivity is a key problem needing solving in process of catalytic reduction.
