Abstract

The invention relates to the technical field of environmental governance and particularly relates to a device for remediation of heavy metal contaminated soil. The device comprises a shell, an anode solution buffer tank and a worm; a cross beam is positioned inside the shell and is connected with the shell through a welding way; a drive motor is positioned above the cross beam and is connected with the cross beam through a fixing way; a worm wheel is arranged at one end of the drive motor and is connected with the drive motor through a fixing way; the worm is positioned on one side of the wormwheel and is connected with the worm wheel through a meshing way; a connecting piece is positioned below the worm and is connected with the worm through a fixing way. Through the structural improvement, the device provided by the invention has the advantages of low manpower consumption, little contact with toxic harmful matters, no secondary pollution, wide application range, large application area and great economic benefits, and thus effectively solves the problems and defects of existing device.

Description

technical field [0001] The invention relates to the technical field of environmental treatment, in particular to a device for treating heavy metal polluted soil. Background technique [0002] According to reports, the area of ​​cultivated land polluted by heavy metals such as cadmium, arsenic, and lead in my country is nearly 20.0×103 km 2 , accounting for about 1 / 5 of the total cultivated land area; among them, 10.0×103km of cultivated land polluted by industrial ‘three wastes’ 2 , the area of ​​farmland irrigated by sewage has reached 3.3×103km 2 , The economic loss caused by various soil pollution is huge. Just taking heavy metal pollution in soil as an example, over 10 million tons of grain are reduced every year due to heavy metal pollution across the country. In addition, the amount of grain polluted by heavy metals is as high as 12 million tons every year, with a total economic loss of at least 20 billion yuan. [0003] Currently, contaminated soil remediation tech...
