| 摘 要： | 时比了天然沸石和合成沸石对制革废水氨态氯的处理效果,分别绘制了吸附等温线.研究了投咖量、温度、pH值、吸附时间、含盐量对吸附效果的影响.结果表明:两种沸石的吸附都更符合Freundlich等温式;当pH=6时,两种沸石的吸附效果最好;温度对沸石的吸附效果影响均较小,NaCl和Na2SO4的加入对天然沸石的影响较大,对合成沸石的影响较小.

| Abstract: | The removals of ammonia nitrogen by natural and synthesized zeolites from tannery wastewater were investigated,with the adsorption isotherms drawn,the effects of adding amount,temperature,pH value,adsorption time,and salt content to the adsorption process were analyzed.The results showed that the processes of ammonium adsorption by both zeolites were fitted to Freundlich adsorption isotherm.The best adsorption reached when pH=6,and the temperature had less affect to both zeolites.The addition of NaCl and Na... |
