NOVELTY - Repairing heavy metal polluted soil by strengthening the chelating agent with fungus, comprises taking fungus having strong tolerance and adsorption capacity on the polluted soil, applying chelating agent to strengthen the absorbing speed and capability of the fungus to the heavy metals in the soil after earth-covering; harvesting the mature fungus after the fungus in the land is mature, placing it in the marsh gas tank to perform reduction treatment of anaerobic microbe fermentation, and making the reduction rate of the fungus biomass reach 60-90%.    USE - The process is useful for repairing heavy metal polluted soil by strengthening the chelating agent with fungus (claimed).    ADVANTAGE - The process fully uses the strong capability of the fungus to enrich heavy metal ions and short growth cycle based on the biological enrichment device of fungus, and combines the strong function of the chelating agent of activating heavy metals; where it reaches a higher efficient repairing effect. Moreover, the subsequent treatment uses chemical deposition and chelating deposition to fundamentally remove the heavy metal ions; and the removing rate of the heavy metal polluted plough land can reach 10-20% per year.    DETAILED DESCRIPTION - Repairing heavy metal polluted soil by strengthening the chelating agent with fungus, comprises taking fungus having strong tolerance and adsorption capacity on the polluted soil, applying chelating agent to strengthen the absorbing speed and capability of the fungus to the heavy metals in the soil after earth-covering; harvesting the mature fungus after the fungus in the land is mature, placing it in the marsh gas tank to perform reduction treatment of anaerobic microbe fermentation, making the reduction rate of the fungus biomass reach 60-90%, concentrating the heavy metals pulled out from the soil in the marsh dreg and marsh liquid, separating out the heavy metals from the marsh liquid by chemical deposition or chelate deposition, discharging the deposited marsh liquid after reaching the standard through detection, and centralizing the heavy metal deposition and marsh dreg to bury.
