为给人工快速渗滤系统提供可行的填料，研究了煅烧贝壳、沸石、麦饭石、蛭石、中砂和细砂对氨氮的吸附效果。实验采用100 mg／L的氯化铵溶液作为初始溶液，结果表明，6种填料均具有快速吸附，缓慢平衡的吸附特点。经过11 h的吸附，煅烧后的贝壳对于氨氮的吸附量为0．993 mg／g。各个氨氮初始浓度梯次下，沸石的最大吸附量均超过其它5种填料，具有明显的氨氮吸附效果。

The ammonia adsorption effects of six kinds of fillings ,such as calcined shell ,zeolite ,maifanite ,vermiculite , moderated coarse sand and fine sand are studied in order to provide feasible fillings for constructed rapid infiltration .The re-sult shows that six kinds of fillings all have the characteristics of rapid adsorption and slow balance .After eleven hours of ad-sorption ,the adsorption amount of calcined shell is 0 .993 mg/g .Under each ammonia initial concentration ,the maximum adsorption amount of zeolite is higher than those of other five kinds of fillings and so zeolite has obvious adsorption effect .
