Full treatment device for soil remediation, and use method thereof

Abstract

The invention discloses a full treatment device for soil remediation, and belongs to the field of soil remediation. The device can effectively separate solid pollutants, collect ferromagnetic substances and perform leaching remediation on soil, and comprises a pretreatment box, a screening box, a retreatment box, a leaching precipitation box and a liquid collection box, wherein the boxes are sequentially distributed from top to bottom, the pretreatment box is provided with a material inlet and a plurality of stirring rods controlled by a driving motor, the outer end portion of the stirring rodis connected to a magnetic adsorption part, the screening box is a vibration type box body controlled by an alternating motor, multiple layers of filtering screens are arranged in the screening box,an inclined hopper opening allowing soil to slide out is formed in the bottom of the screening box, a rolling wheel is arranged at the top of the retreatment box and is controlled to move up and downand left and right by a lifting mechanism and a reciprocating mechanism, a plurality of leaching liquid spraying openings and a material outlet are formed in the side wall of the leaching precipitation box, the bottom of the leaching precipitation box is inclined by a certain angle, a filtering opening is formed in the lower end of the leaching precipitation box, and is connected to the liquid collection box, and the bottoms of the pretreatment box and the retreatment box are openable and are controlled by electromagnetic valves.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a device capable of separating solid waste, recovering ferromagnetic substances, and comprehensively remediating soil pollutants and a method for using the same. Background technique [0002] Soil remediation is a technical measure to restore the normal function of contaminated soil. In the soil remediation industry, there are more than 100 existing soil remediation technologies. [0003] Existing restoration technologies generally include thermodynamic restoration, thermal desorption restoration, incineration restoration, landfill restoration, chemical leaching restoration, compost restoration, and osmotic reaction restoration. Regardless of the remediation method, people focus on soil organic matter, chemical pollution, and heavy metals in the process of soil remediation, but not enough for common daily pollutants (eg: plastic bags, batteries, white daily garbage, was...

AI Technical Summary

Problems solved by technology

Regardless of the remediation method, people focus on the organic matter, chemical pollution, and heavy metals in the soil during the soil remediation process, but do not pay enough attention to common daily pollutants (such as: plastic bags, batteries, white daily garbage, waste paper, etc.) Pay attention, after a long period of accumulation, it will recycle pollution, and some recyclable pollutants will lead to waste of resources

There are some pretreatment equipment on the market to treat these commonly used pollutants in the process of soil remediation, but the use of these equipment often requires manual leak detection, or directly breaks the pollutants by machinery and treats them with the soil. This method It not only consumes manpower, but also increases the difficulty of soil restoration in the later stage and increases the restoration time

[0004] In addition, there are some wastes of resources in the process of soil remediation. For example, there are some discarded ferromagnetic substances (iron sheet, iron sheet) in the soil, which often lead to these problems in the process of soil remediation, especially in the process of chemical leaching. The loss of material, resulting in the waste of resources
