Using column tests,water quality character of leachate and permeability coefficient variation law when leachate passing through the drainage layer in landfill sites were studied,and genetic mechanism of mineral precipitation and its influence on permeability of drainage layer were analyzed.
利用土柱试验,研究了渗沥液渗流经过填埋场排水层的水质特征和渗透系数变化规律,分析了矿物质沉淀的生成机制及其对填埋场排水层渗透性的影响。
