Embodiment 1
[0030] A method for remediating organically polluted soil, comprising the steps of:
[0031] Step S1: Use an excavator to dig 80 cm of the organic contaminated soil, then lay a layer of geomembrane on the bottom of the excavated organic contaminated soil, and then lay a layer of sawdust on the geomembrane until there is no gap;
[0032] Step S2: Mix the organic polluted soil remediation agent and the organic polluted soil evenly, plow up and down, spread the mixed soil on the surface of the sawdust powder, spray water, and keep the humidity of the polluted soil at 15%;
[0033] Step S3: one week later, plant willow saplings with a height of 2 m in the middle of the step S2, and interplant carrots in the interval between willow saplings;
[0034] Step S4: After 2 months, pull out the carrot to complete the restoration.
[0035] The geomembrane is a low-density polyethylene geomembrane.
[0036] The mass ratio of the organic polluted soil restoration agent to the organic pollu...

[0044] A method for remediating organically polluted soil, comprising the steps of:
[0045] Step S1: Use an excavator to dig 85 cm of the organic contaminated soil, then lay a layer of geomembrane on the bottom of the excavated organic contaminated soil, and then lay a layer of sawdust powder on the geomembrane until there is no gap;
[0046] Step S2: Mix the organic polluted soil remediation agent and the organic polluted soil evenly, plow up and down, spread the mixed soil on the surface of the sawdust powder, spray water, and keep the humidity of the polluted soil at 17%;
[0047] Step S3: After one week, plant willow saplings with a height of 2.3m in the middle of the step S2, and interplant carrots in the interval between willow saplings;
[0048] Step S4: After 2.5 months, pull out the carrot to complete the repair.
