Abstract

The invention discloses a testing device and a testing method for restoring the contaminated soil based on magnetism-electricity combination. A restoring device comprises a magnetic field generating area, an anode chamber, a cathode chamber and a soil chamber; the magnetic field generating area is located around in the device, the interior of the magnetic field generating area is a whole box whichis separated into three rectangular boxes by a perforated plate, the middle is the soil chamber, and the two sides are the anode chamber and the cathode chamber. The testing method of a testing device includes the steps of the design of the device, the configuration of the contaminated soil, the restoring testing, the regulation of a single factor, and the repeating of the restoring test. The testing device is low in size, easy to transport and high in space utilization degree, can simulate various working conditions and improve the testing efficiency.

Description

technical field [0001] The invention relates to the technical field of environmental geotechnical engineering, in particular to a test device and a test method for repairing polluted soil based on magneto-electric combination. Background technique [0002] With the rapid development of the national economy, the output of various wastes has increased rapidly, and soil pollution has continued to aggravate. If the environmental investigation, assessment, and pollution control and restoration of polluted sites are not strengthened, the residual pollutants in the soil will affect the city and the living environment, and enter the human body through contact, breathing and other exposure routes, endangering human health. The work of remediation of polluted soil is beneficial in the contemporary era, and its merits will last forever. [0003] At present, soil remediation technologies at home and abroad have their own advantages, but a single remediation technology has certain limit...
