Description

Technical Field

[0001] The utility model relates to the technical field of soil leaching, in particular to a soil leaching reaction device enhanced by ultrasonic mechanical stirring. Background Art

[0002] Soil leaching technology is a commonly used soil remediation method. Its main principle is to inject chemical solvents that can promote the dissolution or migration of soil pollutants into the contaminated soil, so as to dissolve, separate and treat the pollutants from the soil. This technology uses chemical principles to repair contaminated soil. Soil leaching technology has been successfully applied to many fields, such as industrial waste pollution remediation, pesticide residue management and petroleum pollution remediation. Through this technology, heavy metal concentrations can be effectively reduced, pesticide residues can be removed and soil fertility can be restored, so that contaminated soil can meet environmental quality standards. In the process of soil leaching, the soil and the leaching solution need to be fully mixed to improve the leaching effect.
