Abstract

The invention discloses a soil remediation system based on an electric auxiliary permeation technology. The system comprises an extraction well and an injection well which are arranged in polluted soil, and further comprises a soil remediation agent injection device and an electric auxiliary permeation device, the soil remediation agent injection device is mounted in the injection well, and is configured to convey a soil remediation agent into the injection well, the electric auxiliary permeation device comprises a cathode, an anode and a power supply, the cathode is arranged in the extractionwell, the anode is arranged in the injection well, the cathode and the anode are both connected with the power supply, the cathode, the anode and an electrolyte solution composed of liquid in contaminated soil form an electrolytic tank together when the power supply is connected, and the soil remediation agent can automatically permeate into the extraction well from the injection well under the action of the electrolytic tank. The limitation that chemicals are added to the soil layer only in a pressurizing mode traditionally is broken through, the chemical adding effect and stability of the in-situ multi-point chemical injection process can be guaranteed, excessive pressure cannot be applied to the soil layer, and disturbance and damage to the soil layer cannot be caused.

Description

technical field [0001] The invention relates to the field of soil remediation equipment, in particular to a soil remediation system based on electric-assisted infiltration technology. Background technique [0002] Multi-phase extraction (MPE) is one of the main technologies for remediation of soil and groundwater contaminated by volatile organic compounds. The pollutants (nonqueous phase liquid, NAPL) are separated and processed to the ground to achieve the effect of rapid control and simultaneous repair of soil and groundwater pollution. Multiphase extraction (MPE) system usually consists of three main process parts: multiphase extraction, multiphase separation and pollutant treatment. Compared with the traditional extraction treatment method, the most prominent feature of MPE is the use of vacuum or vacuum-assisted methods to realize the migration of pollutants from the underground environment to the surface above. [0003] MPE systems can be divided into single-pump sys...
