At present, stabilization technology is widely used in heavy metal contaminated soil projects. However, since pollutants cannot be completely removed from the soil, the long-term stability of pollutants in the soil after remediation is difficult to ensure, and the soil after remediation is difficult to digest, these unfavorable factors have gradually limited its wide application in engineering. Leaching technology has the advantages of reducing the amount of contaminated soil, completely removing pollution, and making the soil usable after remediation. It is a remediation technology with good application prospects in future projects.

[0003] However, in the prior art, during the use of traditional skid-mounted soil remediation equipment, due to the presence of different pollutants in the soil, if the soil is leached, the agent cannot fully contact with the soil, which affects the soil remediation effect, reduces the working efficiency of the soil remediation equipment, and increases the cost of soil treatment.
