Study on bioremediation technology for environmental treatment in abandoned mining areas
Due to the great impact of abandoned mining areas on the production and life of surrounding residents,a bioremediation tech-nology for environmental treatment of abandoned mining areas was proposed.Through the analysis of phytoremediation mechanism,the remediation effect of vegetation on heavy metal and organic pollution in the mining area was clarified.In combination with microbial re-mediation technology,heavy metal ions were enriched on the surface of cells by electric adsorption and specific adsorption,which can change the valence state of variable valence metal ions,change the form and distribution of heavy metals in the soil,pollute the roots of heavy metals,improve the life cycle of plants,improve the environmental pollution of abandoned mining areas,and realize environmental remediation.Through experiments,it is proved that the proposed technology can repair the environment of abandoned mining areas,re-duce the concentration of heavy metal pollution,and improve the quality of land.
