At present, the research mainly focuses on the combined pollution of organic chelating agents, pesticides, petroleum hydrocarbons and aromatic compounds with heavy metals. Heavy metals and polycyclic aromatic hydrocarbons are two important pollutants in the soil environment, and often enter the soil environment simultaneously or successively to form combined pollution;

[0003] Soil remediation is a technical measure to restore the normal function of polluted soil. In the soil remediation industry, there are more than one hundred existing soil remediation technologies, and there are also more than ten commonly used technologies, which can be roughly divided into three methods: physical, chemical and biological. Soil remediation refers to using physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil, so that their concentration is reduced to an acceptable level, or converting toxic and harmful pollutants into harmless substances

[0004] Most of the existing soil remediation methods are to spray the liquid medicine required for remediation on the soil surface, but the mixing effect between the liquid medicine and the soil is poor during the spraying process, so multiple sprays are required when remediating the soil, which is more cumbersome during the remediation process.
