Abstract

The invention provides integrated efficient leaching equipment for heavy metal contaminated soil, which comprises an efficient fraction screening module configured to perform efficient fraction screening on contaminated soil so as to separate soil with a particle size less than a specified particle size for input into an efficient leaching reaction module, thereby achieving a function of reducingthe leaching remediation amount, an efficient leaching reaction module configured to add a medicament in a corresponding mode for leaching according to a heavy metal pollutant concentration detectionresult and promote a pollutant leaching separation function through efficient stirring and ultrasonic oscillation, and an efficient precipitation and filter pressing module configured to screen and filter the soil discharged by the efficient leaching reaction module.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to an integrated high-efficiency rinsing device for heavy metal-contaminated soil. Background technique [0002] Soil washing technology refers to the technology of injecting chemical solvents that can promote the dissolution or migration of soil pollutants into the polluted soil, so as to dissolve, separate and treat the pollutants from the soil. The technological process can be divided into: soil particle size screening, leaching and separation of heavy metal pollutants, soil and waste liquid treatment after leaching. [0003] At present, there are many links in soil leaching technology, but the effect of leaching and separation of heavy metal contaminated soil is still not good. . In the soil particle size screening process, the soil particles were not effectively separated according to the particle size, resulting in low equipment productivity; in the heavy metal poll...
