摘　　要：研究了在不同改性条件下沸石对氨氮的去除效果,结果表明:0.3 mol.L-1的NaCl溶液在100℃下对沸石的改性效果最佳,氨氮去除率可达87.9%。研究了水样的pH值、吸附时间对改性沸石吸附氨氮的影响。The effect of ammania-nitrogen removal with zeolite under different modified conditions is studied.The results show that zeolite modified by 0.3 mol.L-1 NaCl solution at 100 ℃ has the highest removal efficiency and that NH4-N removal rate can reach 87.9%.This paper also discusses the influences of water pH and contact time on ammonia-nitrogen absorption by activated zeolite.
