Embodiment 1

[0042] Embodiment 1 soil remediation method

[0043] (1) Turn over the soil to be repaired, and dig out the earthwork to be repaired;

[0044] (2) leveling the land to be restored;

[0045] (3) laying a soil remediation film on the leveled land; the soil remediation film refers to a soil remediation film containing carbon-based materials.

[0046] (4) Spread 30cm of earth to be repaired on the soil repair film;

[0047] (5) Sprinkle a layer of carbon-based material on the surface of the earthwork to be repaired; the carbon-based material is spread in the form of a dispersion; The content is 0.5g / 100mL; spread 5g of carbon-based materials per square meter of earthwork surface to be repaired.

[0048] The soil remediation film containing carbon-based material described in step (3) is prepared by the following method:

[0049] Disperse the carbon-based material in water to form a dispersion; then apply the dispersion to both sides of the carbon fiber non-woven fabric, and aft...

Abstract

The invention relates to the technical field of soil remediation, and particularly discloses a soil remediation method. The soil remediation method comprises the following steps that (1) turning oversoil to be remediated, and turning out earthwork to be remediated; (2) leveling the land to be repaired; (3) paving a soil remediation film on the leveled land; (4) paving the earthwork to be remediated on the soil remediation film. The soil remediation film in the step (1) is a soil remediation film containing a carbon-based material. By means of the method, PAHs contaminated soil can be efficiently repaired.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a soil restoration method. Background technique [0002] Polycyclic aromatic hydrocarbons (PAHs) are an important class of persistent organic pollutants ubiquitous in the environment. PAHs are mainly the products of incomplete combustion of fossil fuels and biomass. Soil PAHs pollution comes from a wide range of sources, including atmospheric dry and wet deposition, sewage irrigation, chemical fertilizer and pesticide application, straw burning, etc. Soil is a sink of various pollutants, and can be transformed into a secondary pollution source of other environmental media under certain conditions. PAHs have a large amount of emissions, are semi-volatile, low-solubility, and difficult to biodegrade, and often exist in the soil for a long time and accumulate in large quantities. In 2004, my country's 16 kinds of PAHs emissions were about 114,000 tons, accounting for 22% ...
