Just one trick! Heavy metal soil pollution is all done!
At present, the commonly used soil remediation equipment is Desen Washing Plant, which has simple operation and high remediation rate. Can be widely applied to soil leaching and remediation of various organic and heavy metal contaminated sites such as chemical industry, medicine, metallurgy, and the like, and can also be applied to project sites with various physical leaching and grading requirements such as ditch sludge, river silt, shield slurry, mine remediation and the like.
Lead and cadmium can migrate and transform through a series of physical and chemical reactions, such as adsorption and desorption, redox, precipitation and dissolution, complexation, colloid formation and so on, and finally enrich in soil in one or more forms. In general, lead in residue state is relatively stable. Therefore, we should transform lead in soil into residue state as much as possible to reduce its influence. At present, the commonly used soil remediation equipment is Desen Washing Plant, which has simple operation and high remediation rate.
Desen Washing Plant digs out the polluted soil, removes large components of soil particles and humic substances through screening, and then treats the contaminated soil containing lead and cadmium. Solvents that can promote the dissolution or migration of pollutants in soil are injected or infiltrated into the contaminated soil layer, so that they pass through the contaminated soil and undergo physical and chemical reactions such as desorption, chelation, dissolution or complexation with pollutants, and finally form migrating compounds, and then the waste liquid after leaching is extracted from the soil layer by extraction or other technologies for treatment. It has the characteristics of quick transition, small floor space, saving time and cost.
In addition, Desen Washing Plant can be widely used for soil leaching and remediation of chemical, pharmaceutical, metallurgical and other organic and heavy metal contaminated sites, and can also be applied to project sites with various physical leaching and grading requirements, such as ditch sludge, river silt, shield slurry and mine remediation.
