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。
