Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil remediation operation technology, specifically to an integrated washing vehicle for ex-situ soil washing remediation. Background Technology
[0002] Ex-situ soil leaching remediation is a remediation technology that moves contaminated soil from its original location to another location for treatment. This method involves injecting or infiltrating a leaching solution into the soil, causing the contaminants in the soil to be separated into the water. The contaminants are then removed through solid-liquid separation, and the treated soil can be reused.
[0003] Conventional ex-situ soil washing remediation devices typically mix the chemical solution and soil and then discharge the mixture directly into the device for the next screening operation. The mixing of soil and chemical solution produces a large amount of mud, which is thrown against the inner wall of the mixing tank during the mixing process. This mud adheres to and solidifies on the inner wall of the mixing tank, causing blockages over time that are difficult to clean and will seriously affect the work process. Utility Model Content
