Embodiment Construction
[0048]The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts all involve the protection scope of the present invention.
[0049] Such as Figure 1 ~ Figure 2 As shown, this embodiment proposes a bionic transpiration-based in-situ leaching repair method for contaminated soil, including the following steps:
[0050] S10. Site cleaning: select an open space, clean up the sundries on the open space and compact it;
[0051] S20. Drilling: use the in-situ rinsing device to drill ground holes, and the number of ground holes is at least two;
[0052] S30, adjusting equipment: placing the suction pipe...

The invention relates to the technical field of contaminated soil remediation, and proposes an in-situ leaching and remediation method for contaminated soil based on bionic transpiration, comprising the following steps: site cleaning, drilling, equipment adjustment, decontamination liquid injection, soil surface sewage discharge, soil Drain internally and inject repair fluid. The method also provides an in-situ rinsing device. The in-situ rinsing device includes a traveling mechanism, a controller, a transposition mechanism, a spraying mechanism, a punching mechanism, an anti-volatile mechanism, an air charging and pumping mechanism, and a material barrel. Through the above technical solution, the problem in the related art that it is difficult to popularize the chemical restoration method caused by the poor diffusion effect of the chemical agent in the soil is solved.
Description
technical field [0001] The invention relates to the technical field of contaminated soil remediation, in particular to an in-situ leaching and remediation method for contaminated soil based on bionic transpiration. Background technique [0002] Oil pollution in soil mainly includes hydrocarbons (aliphatic hydrocarbons, aromatic hydrocarbons, etc.), halogenated hydrocarbons and other components (oxygenated compounds, chlorine-containing compounds and sulfur-containing compounds). These organic pollutants mainly come from the leakage of pumps, pipelines, oil tanks and purification equipment in the process of oil extraction, accidental accidents in oil transportation, leakage of underground oil tanks, and leakage or unqualified discharge in the process of coal chemical production. The composition of petroleum pollutants is complex, containing teratogenic, carcinogenic, mutagenic and other substances (halogenated hydrocarbons, benzene series, anilines, phenanthrene, benzopyrene,...
