【摘要】 建立了动态浸出试验——小柱模拟实验系统，研究在非饱和水条件下危险物质在填埋场中的迁移和浸出规律，并和静态浸出实验进行比较⒚结果表明，在非饱和入渗条件下危险物质的浸出浓度要比静态浸出实验的结果小１００倍左右，危险组分的浸出速率也远小于静态实验的结果，同时，危险物质的浸出速率随废物层饱水度的增加而迅速增加更多还原

【Abstract】 A set of dynamic leaching test system was established to simulate the migration and leaching rule of the hazardous components in the unsaturated hazardous waste landfill,and it was compared with the static leaching test The results indicated that the leaching concentration and rate of hazardous components under unsaturated conditions was much lower than that of static leaching test,and the leaching rate of hazardous components was increased dramatically with the increase of the waste saturation更多还原
