摘要
The present invention provides a remediation method for degradation of cadmium in soil. The specific steps are as follows: step 1, determining the content of cadmium in the soil; step 2, crushing and sieving soil from a soil surface, and weighing; step 3, wetting the soil, and removing part of cadmium in the soil to obtain semi-remediated soil; step 4, mixing the semi-remediated soil with a remediation agent, and allowing to stand to obtain improved soil; and step 5, planting Bidens pilosa in the improved soil, and when a growing season is finished, uprooting, and ashing to obtain finished soil. The present invention utilizes anode and cathodes and a remediation agent to treat the cadmium contaminated soil, and plants Bidens pilosa in the soil to achieve a joint effect of electrodynamic remediation, chemical remediation, microbial remediation and phytoremediation to remediate the cadmium contaminated soil.
