Embodiment 1

[0040] Such as figure 1 and figure 2 As shown, a heterotopic magnetic field restoration device for heavy metal contaminated soil is characterized in that it includes a magnetic field generating device 1 , a pollutant collecting device 2 , a contaminated soil stirring device 3 and a power device 4 .

[0041] The overall structure of the magnetic field generating device 1 is a cylindrical structure with upper and lower openings and a hollow interior.

[0042] Such as image 3 As shown, the magnetic field generating device 1 is composed of component I101 and component II102. Said component I101 and component II102 are symmetrical with respect to the axial section of the magnetic field generating device 1 . One end of the component I101 is flexibly connected to one end of the component II102. Said member I101 and member II102 turn on or off the magnetic field generating device 1 around the flexible connection end.

[0043] The movable connection between the member I101 and t...

Abstract

The invention discloses an ectopic magnetic field repairing device for heavy metal contaminated soil. The ectopic magnetic field repairing device is characterized by comprising magnetic field generation equipment, pollutant collection equipment, contaminated soil stirring equipment and power equipment, wherein a vertical-direction magnetic field is supplied to a contaminated soil treatment regionthrough the magnetic field generation equipment, the heavy metal contaminated soil is conveyed to an inlet of the contaminated soil stirring equipment through a conveying belt, the contaminated soil stirring equipment and the heavy metal contaminated soil in the contaminated soil stirring equipment are driven to rotate in a high speed by the power equipment, a magnetic induction line is cut, heavymetal ions are collected by virtue of the pollutant collection equipment, and the repaired heavy metal contaminated soil is output through an outlet. According to the ectopic magnetic field repairingdevice disclosed by the invention is rapid, efficient, low in energy consumption and environment-friendly, the repaired soil particles can be relatively uniform and loose, and the ectopic magnetic field repairing device can play a very important role in the green planning of the sustainable development of human beings.

Description

technical field [0001] The invention relates to the technical field of environmental geotechnical engineering, in particular to an off-site magnetic field restoration device for heavy metal polluted soil. Background technique [0002] With the rapid development of industrialization and urbanization, the output of various wastes is increasing rapidly, soil pollution is increasing, and the environment on which human beings depend is deteriorating. Soil is not only the foundation of agricultural production, but also the foundation of terrestrial ecological environment. Soil quality not only determines the yield, quality and safety of agricultural products, but also directly restricts the quality of ecological environment for human survival. The work of remediation of polluted soil is beneficial in the contemporary era, and its merits will last forever. [0003] A large number of investigations and studies have shown that the soil in our country is seriously polluted by heavy m...
