天然及改性沸石对氨氮废水处理效果的试验研究

Experimental Study on Treatment Effect of Ammonia Nitrogen Waste Water by Zeolite and Modified Zeolite

用山东潍坊涌泉天然沸石及改性沸石进行模拟氨氮废水的脱氮试验研究,结果表明,该地沸石对废水中的氨氮有较高的去除率。沸石及改性沸石对氨氮的对数吸附等温线符合Freundlich方程,直线的斜率均在0.1￣0.5之间,可以作为高浓度氨氮废水的吸附剂使用。

The effect on natural zeolite and modified zeolite from weifang-yongquan of shandong province absorbing the ammonia nitrogen were discussed in this paper. Experiments show that natural zeolite and modified zeolite can absorb the ammonia nitrogen effectively.
