摘要：The residual soil containing heavy metals after solidification/stabilization treatment (test residual soil), was selected as the study object of heavy metal release kinetics. Firstly, the properties of test residual soil were analyzed, and then the test residual soil was placed in the treatment tank and tested under different composite conditions. The test conditions include temperature, simulated rainfall, simulated rainfall pH and simulated light intensity. Different compound conditions were selected for testing, and each composite condition test was conducted in two groups. The experiment lasted 110 days. The simulated rainfall test was conducted every 10 days. The soil samples and leachate samples were sampled at each time. At the same time, the overflow and leachate samples were measured. The heavy metal content in each sample was analyzed and the release rule of heavy metals in the remaining soil was deduced.
