Heavy metal chromium contaminated soil remediation method

Abstract

The invention provides a heavy metal chromium contaminated soil remediation method which comprises the following steps: performing soil loosening treatment on a soil part needing to be remediated through a tractor or other machines, controlling a scarifier through a control unit, performing complete soil loosening treatment on the surface of soil, and driving a soil remediation device to move through a moving unit. Soil remediation operation is carried out on the surface of soil, multiple groups of filter bags for adsorbing high-molecular adsorbent particles of chromium are placed in the soil, clear water is pressurized and fed into the filter bags, and internal remediation treatment is carried out on the soil by means of the pumping principle through pressurized pumping work of a water pumping device; according to the remediation method, compacted soil is dug up and loosened, remediation use of the soil is facilitated, the soil remediation device is driven by the moving unit to move, all procedures are sequentially completed from front to back, and the remediation rate of the contaminated soil is greatly increased; the soil is further subjected to radiation treatment through the radiator, so that the remediation effect is improved.
