Description

Technical Field

[0001] The utility model relates to the technical field of soil excavation and restoration, in particular to a contaminated soil excavation device. Background Art

[0002] Soil pollution can be roughly divided into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium, and fluorine, etc. Organic pollutants mainly include organic pesticides, phenols, cyanide, petroleum, synthetic detergents, and harmful microorganisms brought by urban sewage, sludge and manure. When the soil contains too many harmful substances and exceeds the self-purification capacity of the soil, it will cause changes in the composition, structure and function of the soil, and microbial activity will be inhibited.
