Abstract

The invention relates to a remediation device for soil contamination. The remediation device is used for in-situ remediation of soil and comprises a power supply, a refrigerator, a liquid injection pump, a vacuum pump, a steam-water separator and a freezing-thawing and leaching unit, wherein the freezing-thawing and leaching unit comprises two liquid injecting and water draining plates, two liquidpumping and water draining plates and a freezing pipe; the two liquid pumping and water draining plates are arranged on the outer sides of the freezing pipe; the two liquid injecting and water draining plates are symmetrically arranged on the outer sides of the liquid pumping and water draining plates; the refrigerator is connected to the freezing pipe; a liquid injecting pump is connected to theliquid injecting and water draining plates; the liquid pumping and water draining plates are connected to the steam-water separator; the steam-water separator is connected to the vacuum pump; the twoliquid injecting and water draining plates serve as anodes, and the two liquid pumping and water draining plates serve as cathodes; the liquid injecting and water draining plates and the liquid pumping and water draining plates which are located on the same side of the freezing pipe are connected with the positive electrode and the negative electrode of a power source through wires; and electrodeareas are formed between the liquid injecting and water draining plates and the liquid pumping and water draining plates. Compared with the prior art, the remediation effect of the remediation deviceis improved in the manner of a combination of electric remediation, manual freezing and vertical shaft leaching.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a soil pollution remediation device. Background technique [0002] Soil pollutants can be roughly divided into two categories: inorganic pollutants and organic pollutants. Nowadays, people pay more and more attention to soil pollution, and the control of soil pollution is also in progress. However, the current treatment methods are relatively single and cannot be treated The soil is completely repaired; the pollutants in the soil cannot be eliminated; no machine can repair the soil, and manual repair is mainly used. [0003] Chinese patent CN108326037A discloses a soil pollution remediation device, including a bottom plate, a barrel body, a motor, a first gear, a second gear, a hollow shaft, a screen, a support plate, a mounting shaft, a third gear, an inner gear, and a hollow stirring Rod, spray box, inoculation box, disc, movable rod, piston rod, cylinder body and pis...
