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.
