Through the research of this paper, a conclusion can be drew: NaCl treatment raise the NH4＋-N removal ratio obviously by 18%, and is better than treating by heating, H2SO4, HCl and NaOH. The most reasonable concentration of NaCl is 0.8~1.0mol/L considering technical, economic and other factors synthetically; The best conditions of NaCl modifying is as follows : temperature 70~75℃, time 2.5hours, granularity ＜120mesh, volume/mass 25ml/g; As additive forming pores, activate carbon powder is a little better than charcoal powder, but the effect of both is much better than sawdust.

通过本论文的研究得出以下结论：NaCl改性能明显提高沸石对氨氮的去除效率，氨氮去除率提高了18%以上，其改性效果优于加热、H2SO4、HCl、NaOH等处理方法，综合考虑技术经济等因素的影响，取0.8～1.0mol/L为最合理的改性浓度；NaCl改性的最佳条件如下：温度70～75℃，时间2.5h，沸石粒径＜120目，体积质量比25ml/g；作为微孔沸石的造孔剂，活性炭粉略优于木炭粉，但二者的效果均比木屑好得多。
