Abstract
A method for repairing an organic polluted site includes the following steps: step 1, build a sunlight greenhouse; step 2, carry out pretreatment to the soil of the organic polluted site; step 3, perform a biological heap treatment on the pretreated soil; step 4, implement quality control on the biological heap for soil remediation. By constructing a sunlight greenhouse within the original site of organic pollution sites, placing a biological heap in the sunlight greenhouse for a biological heap treatment, using the heat accumulated in the sunlight greenhouse to promote the volatilization of volatile organic matters in the soil without causing secondary pollution, and meanwhile adding a microbial agent and a nutritional agent to the polluted soil to promote the degradation and conversion of adsorbed organic matters.
