[0002] With the acceleration of industrialization, soil pollution has become increasingly serious, especially heavy metal pollution, which has posed a serious threat to the environment and human health. These heavy metals are difficult to be naturally degraded in the soil, have long-term stability and accumulation, and can exist in the soil for a long time, causing damage to the soil ecosystem.

[0003] The existing heavy metal separation requires that the soil be crushed first to increase the surface area of ​​the soil particles and the exposure of the heavy metals, thereby improving the separation efficiency of the heavy metals. The soil containing the heavy metals is then placed in a heating container for heating so that the heavy metals in the soil are vaporized and separated from the soil.
