Treatment device for soil polluted by medium-low-concentration insulating oil

The utility model relates to a medium/low-concentration insulating oil polluted soil treatment device which comprises a dispersing and sampling unit, the output end of the dispersing and sampling unit is connected with a light wave degradation unit and a corona degradation unit, the light wave degradation unit and the corona degradation unit are respectively provided with a microwave-assisted unit, and the microwave-assisted unit is connected with a microwave-assisted power supply. The light wave degradation unit is connected with a negative pressure collection unit, the corona degradation unit is connected with an air purification unit, and the light wave degradation unit and the corona degradation unit are connected with a soil circulation system; the device is high in practicability and very easy to operate, different contaminated soil can be effectively degraded, the degraded soil is subjected to micro-ecological restoration, and finally the contaminated soil combined near-zero green treatment technology
