| titleOfInvention | Method for treating high-concentration lead-polluted soil by using composite reagent |
| abstract | The invention relates to the field of soil remediation, in particular to a method for treating lead-polluted soil by using a composite medicament, which comprises the following steps: mixing the polluted soil and the organic sulfur chelating agent, stirring for 10-30 min to uniformly mix the soil and the agent to obtain a mixture A, wherein the adding amount of the mixture A is 2-8% of the dry weight of the soil; mixing the mixture A and the modified clay mineral material, and stirring for 10-30 min to uniformly mix the mixture A and the modified clay mineral material to obtain a mixture B, wherein the adding amount of the mixture B is 2-10% of the dry weight of the soil; adjusting the water content of the mixture B to 25-40%, and maintaining for 12-24 hours; and adding 5-15% of hydrated lime into the cured mixture B, and uniformly mixing for 48 hours. |
