Problems solved by technology
[0004] The technical problem to be solved by the present invention is to provide a soil remediation method combining adsorption and magnetic separation. Through the two operating processes of adsorbent delivery and recovery, the pollution-free removal of heavy metals and pesticides in the soil from the soil can be achieved. Harmful separation, avoiding the secondary pollution of the soil caused by the residue of the adsorbent in the soil, is a combination of adsorption and magnetic separation technology, and is a green and environmentally friendly soil restoration method

The invention provides a soil restoration method combining adsorption and magnetic separation, which comprises the following steps: 1, a car body advances, so that soil is moved into a soil cutting shovel of a soil conveying device, and then the soil is lifted and conveyed to be above a crushing device through a conveyor of the soil conveying device and a material lifting device of the soil conveying device; 2, the crushing device performs crushing operation on the soil, and adsorbent drop and recovery operations can be performed, wherein when the adsorbent drop operation is performed, magnetic adsorbent is dropped into an adsorbent drop hopper, and at this time, a magnetic separation device is not started; 3, the magnetic adsorbent and the soil are mixed, then fall into a material stirring and conveying device, and are conveyed to the tail part of the car while being stirred and mixed; and 4, recovery operation is performed, the magnetic separation device is started, and the magnetic adsorbent is sucked on a magnetic roll body and discharged into an adsorbent recovery hopper after the magnetic roll body is rotated to a high position. According to the invention, through two operation processes of adsorbent drop and adsorbent recovery, the harmless separation between pollutants such as heavy metal, pesticide and the like in the soil and the soil can be realized.
Description
technical field [0001] The invention relates to a contaminated soil remediation technology in the field of environmental protection, belongs to the technical field of contaminated soil remediation, and in particular relates to a soil remediation method combining adsorption and magnetic separation. Background technique [0002] With the continuous acceleration of industrialization and urbanization, the pollution of heavy metals and organic substances in my country's soil has become more and more prominent. Serious environmental hazards caused by pollution have occurred from time to time and are gradually increasing. According to data, 20 million hectares of land has been polluted by heavy metals nationwide, of which more than 700,000 hectares are seriously polluted, and 130,000 hectares of land have been abandoned due to excessive cadmium content. Soil heavy metal and organic pollution will reduce the quality of agricultural products, affect the quality and use value of soil,...
