Among them, soil remediation is a technical measure for restoring normal functions of contaminated soil, and the most commonly used methods for soil remediation include three methods, i.e., a physical method, a chemical method and a biological method.
Chemical remediation refers to a process that utilizes chemical decomposition or immobilization reactions to change the structure of a contaminant or reduce the mobility and toxicity of a contaminant. Mainly based on the improvement measures of the chemical behavior change of the pollutants, such as adding chemicals such as modifying agents, inhibitors and the like to reduce the water solubility, diffusivity and bioavailability of the pollutants in the soil, so that the pollutants are degraded or converted into low-toxicity and low-mobility forms. The chemical remediation technology is a remediation technology for reducing the migration, effectiveness and toxicity of pollutants in soil by methods of precipitation, adsorption, oxidation-reduction, catalytic oxidation, proton transfer, dechlorination, polymerization, hydrolysis and the like.
For repairing soil with shallow soil layer, only the reducing agent is sprayed on the surface of the soil and then ploughed, so that the repairing effect is achieved after the reducing agent is combined with the soil.
