砂石过滤河水中氨氮的吸附机制分析

Adsorption Mechanism of Ammonia Nitrogen in River Water Filtered by Sand and Gravel

为了研究砂石过滤吸附水中有机物的规律和性能,以西宁市湟水河水为研究对象,研究其对水溶液中氨氮的等温吸附特性,利用一级动力学模型、二级动力学模型对砂石吸附氨氮动力学过程进行了分析。

To study the regularity and performance of adsorption of organic compounds in water by sand filtration,in Xining City Huangshui River as the research object,the isothermal adsorption characteristics of ammonia nitrogen in aqueous solution were studied,by using a kinetic model,two stage kinetic model was used to analyze the dynamic process of ammonia nitrogen adsorption by sand and gravel.
