| Zusammenfassung: | The invention relates to a soil remediation method for treating heavy metal pollutants. The soil is divided into three classes according to the heavy metal content in the soil, namely, heavily contaminated soil, moderately contaminated soil and lightly contaminated soil. The soil remediation method for the heavily contaminated soil comprises the steps of chemical leaching, earthworm enrichment remediation and phytoremediation; the soil remediation method for the moderately contaminated soil comprises the steps of earthworm enrichment remediation and phytoremediation; and the soil remediation method for the lightly contaminated soil is phytoremediation. The invention combines the animal/plant enhanced composite remediation, realizes in-situ bioremediation of the soil successfully and has obvious effect without causing secondary pollution to the soil. |
