Description

In-situ leaching repair equipment for soil regeneration

Technical Field

The invention relates to in-situ leaching repair equipment for soil regeneration, and mainly relates to the technical field of soil repair.

Background

Soil pollutants can be broadly classified into two broad categories, inorganic pollutants and organic pollutants. The inorganic pollutants mainly comprise acid, alkali, heavy metal, salts, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium and fluorine, and the like. The organic pollutants mainly comprise organic pesticides, phenols, cyanides, petroleum, synthetic detergents, 3, 4-benzopyrene, harmful microorganisms brought by municipal sewage, sludge and animal manure, and the like. When the soil contains excessive harmful substances and exceeds the self-cleaning capacity of the soil, the composition, the structure and the function of the soil are changed, the activity of microorganisms is inhibited, and the harmful substances or decomposition products thereof are gradually accumulated in the soil and are indirectly absorbed by the human body through the soil → plants → the human body or through the soil → water → the human body, so that the degree of harming the health of the human body is reached, namely the soil pollution;

an important method for remediating contaminated soil is a soil leaching technique, which is a technique for injecting a chemical solvent capable of promoting dissolution or migration of soil contaminants into contaminated soil, thereby dissolving, separating and treating the contaminants from the soil. Soil washing is different from soil washing. The soil washing is to wash the polluted soil by using clear water, and transfer organic and inorganic pollutants attached to the surface of soil particles into an aqueous solution, so as to achieve the purposes of washing and cleaning the polluted soil;
