| 摘 要： | 用不同比例的沸石对天然粘土进行改性,对改性粘土防渗层的渗透性、去除主要污染物的有效性和控制渗滤液渗透的可行性进行研究。实验结果表明改性粘土防渗层的渗透系数随沸石比例的增加而增大,如果沸石的配比适当,其渗透系数可达到低于1×10-7cm/s的现行标准,而且提高了防渗层的污染物去除能力。因此,沸石改性粘土作为垃圾填埋场防渗材料是可行的。

| Abstract: | Different percentage of zeolites was used to modify natural clay to study permeability, contaminants-removal ability and feasibility of leachate leaking control of zeolites modified clay-liners. Experiment results indicated that the permeability of liner is proportional to percentage of zeolites. If the ratio of zeolites and clay is proper. the/(permeability of liner can be less than current standard of 1 X 10 ' cm/s. and the pollutants-removal ability is enhanced. Therefore, it is feasible that zeolites modified natural clay can be used as material of landfill liners. |
