摘要
膨润土及其产品GCL正广泛应用于城市垃圾填埋场的防渗系统中。但是膨润土的膨胀性能在成分复杂的液体(如渗滤液)中会大幅下降,从而直接影响防渗效果。在分析中,利用丙二醇碳酸酯对钠基膨润土进行活化,提高其耐化学性,并分析了其性能改善的机理。
Bentonite and GCL are widely used in barrier systems of MSW landfill. But the swelling characteristics of bentonite will be intensely reduced in complex solution such as leachate. This research activates bentonite with propylene carbonate to increase its chemical resistance and analyses the mechanism.
