摘要
沸石既是氨氮的吸附剂也是硝化细菌的生长介质。介绍了生物沸石脱氨氮技术的国内外研究进展,分析了生物沸石脱氨氮新技术的原理并对其在制革废水脱氨氮中的应用进行了展望。
Zeolite is an adsorbent for ammonia-nitrogen, also a growing media for nitrobacteria. The research advances on removal of ammonia - nitrogen by biological zeolite at home and abroad were introduced, and principles of the new technique were analyzed and its application was prospected.
