污水处理中氨氮吸附剂的类型及经济性比较分析

Type and Economic Comparison of Ammonia Nitrogen Adsorbents in Sewage Treatment

介绍了目前国内外对污水中氨氮吸附效果较好的几种吸附剂,论述了这些吸附剂的基本结构、对氨氮的吸附机理、性能特点、改性方法、研究现状、在我国的分布情况以及氨氮吸附剂联用的应用现状。以阜新地区丰富的沸石、粉煤灰和膨润土资源为例,在同等条件下,分析、计算比较了各自吸附氨氮的水处理成本,结果表明沸石比较经济。在实际应用中,要因地制宜选择一种高性价比的氨氮吸附剂。

This paper described several adsorbents in sewage treatment which have good adsorption effect to ammonia at home and abroad,discussed the basic structure of these adsorbents,the adsorption mechanism of ammonia nitrogen,performance characteristics,modification methods and research situation,the distribution in China as well as the application of Ammonia-nitrogen adsorbents combine with other adsorbents. Took Fuxin for example,this region has a rich zeolite,fly ash and bentonite resources,and through the analyzed,computation and comparison of each costs of water treatment by ammonia adsorption under the same conditions,the outcome has proved that the zeolite is more economical,meanwhile,we must choose a high cost effective rate of adsorbent in light of local conditions in practical exploitation.
