Ammonia-nitrogen wastewater was treated by natural zeolite, and the saturated zeolite was regenerated by NaCl solution. The breakthrough curves of zeolite before and after regeneration were measured. Ammonia-nitrogen was removed from the rich ammonia-nitrogen regeneration solution through chemical precipitation, and the reuse effect of regeneration solution was investigated. Results showed that zeolite had a good capacity for ammonia-nitrogen wastewater treatment. Breakthrough time of regenerated zeolite extended from 60 min to 160 min. After nitrogen desorption, the ammonium concentration of the used regeneration solution decreased from 141. 6 mg/L to 12. 65 mg/L. The reused regeneration solution regenerated zeolite again, and the breakthrough time delayed to 120 min.%使用沸石对氨氮废水进行交换处理,沸石吸附氨氮(NH4+ -N)饱和后用NaCl溶液对其再生,研究再生前后沸石的交换穿透曲线.采用化学沉淀法对富含NH4+ -N的再生液进行脱氮并考察其回收利用效果.结果表明:沸石对氨氯废水有很好的处理效果,再生沸石的动态交换穿透时间由60min延长到160min；对沸石进行再生处理后的再生液经脱氮处理,得到NH4+ -N质量浓度由141.6 mg/L降至12.65 mg/L.回收利用的再生液再生沸石的穿透时间延长到120min.
