摘 要：
以焙烧、活化后的煤系高岭土为吸附材料,研究了其对生活污水中氨氮的吸附影响及规律。结果表明,煤系高岭土经700℃左右焙烧、活化后吸附率达到最大值,对生活污水中氨氮的最佳用量为20g/L,其吸附平衡时间为60min,饱和吸附量为4.32mg/g,吸附行为更符合Elovich吸附动力学方程。

摘 要：
The effect and discipline of roasting and activated coal-serial kaolin on the adsorption of ammonia nitrogen in municipal sewage were studied.The results showed the adsorption rate could be maximum when the coal-serial kaolin was roasted about at 700 ℃ and actived by dilute sulphuric acid.The best dosage of actived coal-serial kaolin to ammonia nitrogen in municipal sewage was 20 g/L.The balance time of the adsorption was 60 min,and saturation adsorption capacity was 4.32 mg/g,and the adsorption action in accordance with adsorption dynamics of Elovich.
