天然斜发沸石吸附高浓度氨氮废水试验研究

Experimental study on absorbing ammonia nitrogen waste water of high concentration by clinoptilolite

用山东滩坊某地天然斜发沸石，对模拟高浓度氨氮废水进行脱氮试验研究，结果表明，该地沸石对废水中的氨氮有较高的去除率，对氨氮的对数吸附等温线符合Freundlich方程，直线的斜率在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 clinoptilolite from Weifang of Shandong province absorbing the ammonia nitrogen of high Concentration were discussed in this paper. Experiments show that clinoptilolite can absorb the ammonia nitrogen effectively.
