Abstract

The invention discloses a heavy metal contaminated soil remediation device, and belongs to the technical field of soil remediation. The remediation device comprises a soil filtering mechanism, a spiral feeding machine, a remediation box, a soil air-drying mechanism, a crushing mechanism and a soil turning and leaching mechanism. A horizontally-arranged filtering plate is arranged in the remediation box and is provided with screening holes. The soil turning and leaching mechanism comprises a driving motor, a soil turning assembly, a reciprocating vibration assembly, a rotating shaft and two spraying pipelines, and an atomizing nozzle is arranged at the liquid outlet end of each spraying pipeline. A material guiding sliding way is arranged at the bottom of the remediation box, and a closingplate is arranged on the right side of the material guiding sliding way. Through the soil turning and leaching mechanism, soil can be leached and can be turned so that the soil can be evenly leached;and the soil can be crushed under the action of the crushing mechanism so that the soil is crushed into small particles and the soil and reactants fully react.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a heavy metal contaminated soil remediation device. Background technique [0002] With the rapid development of my country's economy and the acceleration of urbanization and industrialization, the problem of soil and groundwater pollution in my country has become increasingly prominent. The activity of heavy metals in the soil is quite high. If the external environment changes slightly, it will dissolve into the soil solution, or enter Runoff pollutes groundwater and surface water, or is absorbed by plants and enters the plant chain to endanger humans and animals. Taking cadmium as an example, the background value in polluted areas is generally high. In some polluted areas, the cadmium content of rice is more than ten times the average value of clear irrigation areas, and vegetables are even as high as dozens of times. Obviously, agricultural land polluted by heavy metal...
