Embodiment 1
[0024] An ecological environment-friendly soil remediation method, characterized in that it includes the following steps: evenly sprinkle the soil remediation agent on the surface of the heavy metal-contaminated soil, then perform soil plowing to fully mix the soil remediation agent and the heavy metal-contaminated soil, and complete the balance in 6 days Soil heavy metal remediation process;
[0025] In parts by weight, the soil remediation agent is mixed with 55 parts of modified hectorite, 20 parts of organic fertilizer, 10 parts of humic acid and 1 part of microbial agent, and the modified hectorite is prepared by the following method : Calcining the hectorite, then adding a mixed modifier to stir the reaction, carrying out microwave irradiation treatment while stirring, and finally grinding it into granules or powder, the stirring reaction is carried out at a temperature of 280° C. for 1 hour;
[0026] The consumption of described mixed modifying agent accounts for the 10...
