Soil remediation method for treating chemical pollution

The invention relates to a soil remediation method for treating chemical pollution, which comprises the following steps: 1) sampling soil in a local area in a region with serious soil pollution; (2) taking out a small part of the sample soil, putting the sample soil into a stirrer, adding water to smash, and putting the sample soil into a detection instrument to detect so as to detect the content of the heavy metal ions in the sample soil; 3) dividing the sample soil into two parts, and respectively putting the two parts into different containers; (4) different amounts of water are added into the two containers, so that the water content of the soil is different; and (5) adding metal passivators or metal regulators in different proportions into the two capacities, so that the metal passivators or the metal regulators are fully mixed with the soil. According to the remediation method for treating the chemically polluted soil, through experimental comparison, the component proportion of a metal passivator or a
