Traditional methods for controlling heavy metal pollution in soil include engineering measures, such as exotic soil, soil replacement and deep ploughing, physical and chemical remediation, such as electro-remediation, electro-remediation and soil leaching, and bioremediation through biological reduction to purify heavy metals in soil or reduce their toxicity. However, these methods have great shortcomings: engineering measures are classic measures to control soil heavy metal pollution, which have the advantages of thoroughness and stability, but the amount of engineering implementation is large, the investment cost is high, the soil structure is destroyed, and the soil fertility is reduced, so the replaced polluted soil must be piled up or treated; Physical and chemical remediation belongs to in-situ remediation, which can shorten the remediation time without stirring the soil layer, but it consumes a lot of electricity. The difficulty of bioremediation lies in finding heavy metal-tolerant plants and microorganisms that can adsorb a certain metal or a certain family or a certain series of metals. The investigation cost is high, and it is impossible to draw accurate conclusions in a short time.
The treatment scheme of soil heavy metal pollution is an in-situ remediation scheme of soil heavy metal pollution developed by Dr. Heavy Metal. This method reduces the bioavailability of heavy metals, mineralizes heavy metal particles, and loses the conditions for reaction with the outside world, thus reducing the concentration of heavy metals in the soil by adding targeted heavy metal stabilizers to the soil and utilizing the adsorption, oxidation-reduction, antagonism or precipitation of heavy metals by the stabilizers. This method can restore the soil in situ and save the transportation cost and storage site cost; Environmental pollution is small, and the damage to the environment can be minimized.
