摘　　要：对用天然沸石和用ＮａＣｌ再生处理后的沸石去除不同氨氮浓度废水中的氨氮的实验进行了研究，结果表明，天然沸石和再生沸石均对含氨氮废水有一定去除效果。其去除原理主要为沸石对非离子氨的吸附作用和与离子氨的离子交换作用，且前者总强于后者。Making a study on the tests of removing ammonia-nitrogen from waste water with different concentration of ammonia-nitrogen by using natural zeolite and regenerated zeolite (with NaCl).The results show that both natural and regenerated zeolite can remove ammonia-nitrogen from waste water to a certain degree.The removal function is based on the absorption of zeolite for nonionic ammonia and on the ion-exchange of zeolite with ionic ammonia ,and the former is always stronger than the latter .
