| Abstract: |
| There are many types and production of non-ferrous metals in China and heavy metal pollutions exist in the soil of non-ferrous metal mining areas. The sources of heavy metal pollution in non-ferrous metal mining areas were introduced. The different remediation technologies of heavy metal contaminated soil in mining areas were expounded. The guest soil method, soil exchange method, glass immobilization, and thermal desorption technology are suitable for soil remediation in a small range. Soil leaching and chemical stabilization remediation are more efficient, but because of the need for admixture, improper treatment can easily cause secondary pollution. Compared with physical and chemical restoration, biological restoration is more economical and environmentally friendly, suitable for large-scale restoration in engineering, which is conducive to the long-term development of the ecology of the mining area. At the same time, the development direction of heavy metal pollution soil treatment in mining areas was prospected, so as to provide a reference for the protection of soil ecological environment in non-ferrous metal mining areas. |
