Embodiment 1

[0029] An electrodynamic restoration system for heavy metal pollutants, the electrodynamic restoration system includes: a treatment box 1, and an accommodating space is provided in the treatment box 1, and soil can be accommodated in the accommodating space;

[0030] Specifically, the treatment box 1 is a semicircular tank type treatment box 1. The semicircular tank type treatment box 1 is made of glass fiber reinforced plastic material, which has the advantages of high temperature resistance, corrosion resistance, insulation and rigidity. Compared with other geometric shapes, the structure has better electrodialysis effect, and at the same time, the structure is more convenient for the subsequent treatment of polluted soil.

[0031] Electrode plate; the electrode plate includes: a first electrode plate 21, the first electrode plate 21 is arranged on the left side of the accommodating space; a second electrode plate 22, the second electrode plate 22 is arranged on the left side...

Abstract

The embodiment of the invention provides an electric restoration system of heavy metal pollutants and belongs to the technical field of soil restoration. The electric restoration system comprises a treatment box, an electrode plate, a water treatment assembly and a conveying assembly, wherein a containing space is arranged in the treatment box, and soil can be contained in the containing space; the input end and the output end of the water treatment assembly are correspondingly connected with the two sides of the containing space, and the water treatment assembly can be used for treating liquid containing heavy metal ions; the electrode plate can be connected with a power source to perform electrolytic operation on the soil, so that the liquid containing the heavy metal ions is generated,and the liquid containing the heavy metal ions is treated through the water treatment assembly. The technical effects that high efficiency of electric restoration is kept, the operation duration is shortened, and the electricity consumption during single-time operation is lowered.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to an electrodynamic remediation system for heavy metal pollutants. Background technique [0002] The basic principle of electrokinetic restoration is to insert the electrode into the contaminated soil. After applying direct current, the aqueous solution in the soil pores generates electroosmotic flow, which makes the charged metal cations migrate to the cathode, and the charged anions migrate to the anode at the same time. The superimposed movement of the heavy metal pollutants leaves the soil in the treatment area and is removed at the positive and negative poles through deposition or ion exchange, adsorption, extraction, etc., so as to achieve the purpose of restoration. During the electrokinetic restoration process, phenomena such as electrolysis, electrodialysis, and electromigration can occur, and the main influencing factors include water electrolysis, soil propertie...
