Embodiment Construction

[0011] Soil is a porous medium consisting of three parts: solid particles, water and gas. In contaminated soil, solid particles, water and gases may adsorb or contain pollutants. In the process of soil remediation, the soil remediation agent is used to contact the pollutants contained in solid particles, water and gas, and have a physical and chemical coupling reaction with them to achieve the purpose of soil remediation.

[0012] Prepackage the calculated safe amount of explosives into explosive packs (1), or use non-explosive explosive sources, put several explosive packs into the packaging container, and fill the soil remediation agent (2); the explosives and soil remediation agent are packaged Finally, a geometric layout is adopted and scattered in the polluted soil (3); explosives and soil remediation agent packaging containers are arranged behind the polluted soil, and measures should be taken to seal and compact the shaft to prevent the explosion from breaking through t...

Abstract

Belonging to the environmental technology field, the invention provides a micro-explosion soil remediation method, which enables a soil remediation agent to rapidly and fully disperse into polluted soil. Commonly used soil remediation chemicals include oxidizing agents and reducing agents, like potassium permanganate, low concentration hydrogen peroxide, a Fenton reagent, iron powder, surfactants and a variety of composite remediation agents. The micro-explosion soil remediation method aims to enhance the dispersion sufficiency and dispersion speed of chemicals in soil, enable rapid and full dispersion of chemicals into polluted soil and achieve a high degree of dispersion. The remediation method is especially suitable for conditional in-situ soil remediation engineering.

Description

technical field [0001] The invention belongs to the field of environmental technology. Background technique [0002] Soil remediation involves removing contaminants from contaminated soil. Depending on the location of the soil during remediation, there are two methods: in-situ remediation and ex-situ remediation. There are many specific soil remediation technologies. From the basic principles, there are physical, chemical and biological soil remediation technologies. [0003] Among them, the chemical remediation technology requires the frequent use of chemicals, that is, soil remediation agents; through the chemical reaction between the soil remediation agent and the pollutants in the soil, the pollutants are changed, the chemical substances are decomposed and destroyed, and the toxicity of the pollutants is eliminated or reduced. Reduce the migration and diffusion activity of pollutants. Commonly used soil remediation chemicals include oxidants and reductants, such as po...
