【摘要】 本文研究了天然沸石在动态下去除ＮＨ４－ Ｎ效果及一些影响因素。结果表明，杂质明显影响着沸石床层的穿透点，小颗粒样品的效果优于大颗粒沸石，最小床层深度较小，特别是在低温条件下效果更显著，同时，小颗粒沸石有利于再生。在床层压力降允许的条件下，尽可能使用小粒径沸石更多还原

【Abstract】 NH + 4 ion exchange on the zeolite and some factors affecting the removal rate were studied, by using dynamic method. It was shown that the efficiency for removing NH + 4 was influenced by the level of impurities in water, zeolite particle size, temperature, etc. Zeolite regeneration efficiency was discussed too.更多还原
