摘　　要：氨氮不仅是生活污水主要污染物之一,也是引起水体富营养化主要因素之一.不少研究对蛭石、蒙脱石、沸石、离子交换树脂等常见离子交换材料在氨氮废水处理中的应用进行了探索,取得了不同的处理效果.文中基于已有研究结果,对这几种常用离子交换材料的结构特性、离子交换和吸附机理进行了对比分析,介绍了其在氨氮废水处理中的应用现状,对将离子交换法和生物法联合实施氨氮废水综合治理的新策略及其应用前景进行了探讨.Ammonia-nitrogen is not only one of the main pollutants in sewage, but also one of the main factors that cause the eutrophication of water body. Vermiculite, montmorillonite, zeolite and ion exchange resin are common but efficient ion exchange materials; therefore, their potential as ammonia-nitrogen adsorbents for wastewater treatment were extensively explored, and varied effects were reported. Based on the existing research results, the paper comparatively analyzes these commonly used ion exchange materials in terms of their structural characteristics, ion exchange and adsorption mechanisms. The status quo of their applications in ammonia-nitrogen wastewater treatment is introduced, and the application prospect of a new strategy that combines the effects of ion-exchange and biological activity for ammonia-nitrogen wastewater treatment is discussed.
