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...

Embodiment 2

[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.

[0049] The geomembrane is a high-density polyethylene geomembrane.

Embodiment 3

[0058] A method for remediating organically polluted soil, comprising the steps of:

[0059] Step S1: Use an excavator to dig 90 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;

[0060] 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 18%;

[0061] Step S3: After one week, plant willow saplings with a height of 2.6m in the middle of the step S2, and interplant carrots in the willow sapling intervals;

[0062] Step S4: After 3 months, pull out the carrot to complete the repair.

[0063] The geomembrane is an ethylene-vinyl acetate copolymer geomembrane.

[0064] The mass ratio of the organic polluted soil remediation agent to the organic p...

Abstract

The invention provides an organic pollution soil restoration method, which comprises the following steps of (1) laying a geomembrane and sawdust powder; (2) mixing organic pollution soil restoration agents and organic pollution soil; (3) planting willow seedlings and carrots; (4) pulling out the carrots. The invention also provides a preparation method of an organic pollution soil restoration agent. Each embodiment can realize the safe fast convenient and efficient restoration of the organic pollution soil; the restoration cost is reduced; the occurrence of secondary pollution is reduced.

Description

technical field [0001] The present application relates to the technical field of ecological pollution control, in particular to a method for repairing organic polluted soil. Background technique [0002] With the acceleration of urbanization and industrialization, the organic pollution of soil in our country is quite serious, and the impact on agricultural products and human health has become increasingly obvious. The main sources of organic pollution are the use of organic pesticides and unreasonable discharge of industrial waste. The types of pollution mainly include organic pesticides, polycyclic aromatic hydrocarbons, halogenated hydrocarbons, and phthalates. Most of these pollutants It is insoluble, toxic, mutagenic, and carcinogenic, and has great harm to human health and ecosystems, and seriously affects the use of land. [0003] The remediation technologies of organic contaminated soil mainly include four categories: physical remediation, chemical remediation, physi...
