Abstract

The invention discloses a magnetic-assistance electrokinetic remediation device for contaminated soil. According to the magnetic-assistance electrokinetic remediation device for the contaminated soil, contaminants in the contaminated soil can be enriched in a regulated area in an acceleration mode through the effect of an extra electric field and the effect of an extra magnetic field, so that the purpose of cleaning the contaminated soil is achieved. The magnetic-assistance electrokinetic remediation device for the contaminated soil comprises an electrode liquid addition tube, an anode plate, a processing area, a cathode column, an electrode chamber, a magnet, an outer shell and an electrode liquid discharging tube. The contaminated soil is placed into the processing area, electrode liquid enters the area of the electrode chamber through a pipeline, the contaminants in the contaminated soil can rapidly transfer through the extra electric field and the extra magnetic field, and the concentration of the partial contaminants is improved. The magnetic-assistance electrokinetic remediation device for the contaminated soil is simple in structure, low in construction cost and easy to operate, can achieve degradation and removal of various contaminants in the contaminated soil.

Description

technical field [0001] The invention belongs to the technical field of contaminated soil treatment, in particular, it relates to a magnetic-assisted electric restoration device for contaminated soil, which is used for processing heavy metals or organic pollutants in the polluted soil. Background technique [0002] As a typical compound polluted medium, soil pollution is cumulative, hysteresis, concealment and irreversible, and it is extremely difficult to restore and deal with it. Pollutants in the soil can enter the soil through various channels, causing changes in the properties, composition and properties of the soil, and destroying the natural dynamic balance of the soil, resulting in soil natural dysfunction, deterioration of soil quality, and affecting the growth and development of crops. The yield and quality of the food will decline, produce certain environmental effects, and pose a threat to organisms and humans through the food chain. [0003] At present, researc...
