摘　　要： 采用振荡试验研究了天然沸石对废水中氨氮的去除效果.研究结果表明:所选材料对废水中氨氮具有较好、较稳定的吸收效果,沸石投加量、废水pH值、反应时间、振荡速度和沸石粒径对沸石去除废水中氨氮的效果均有不同程度的影响.实验证明最优试验条件是:沸石投加量为3.0 g、废水pH值为4、反应时间为90 min、振荡速度为125 r/min及沸石粒径为5.0 mm.在该最优条件下沸石对废水中氨氮的去除率达到80%以上. A batch experiment was conducted to investigate the removal efficiency of ammonium-nitrogen wastewater. The results showed that the selected materials have better and more stable absorptive effect. The rerffoval efficiency of ammonium-nitrogen wastewater was influened by dosage, pH value, reaction time, rotate speed and grain size. The perfect removal efficiency were performed with the pH number being about 4, aditive amount of 3.0 g, the diameter of zeolites being 5.0 mm and the reaction time for about 90 minutes. The highest removal efficiency of ammonium-nitrogen was up to 80%.
