Aeration groundwater pollution remediation device and method

The invention discloses an aeration groundwater pollution remediation device and method. The aeration groundwater pollution remediation device comprises underground wells, aeration equipment and air extraction equipment, wherein the underground wells comprise a main well and a plurality of inclined wells; the main well is arranged on the ground; the bottom of the main well is submerged into a pollution plume; the inclined wells are arranged in an unsaturated zone; the aeration equipment comprises an aerator, an aeration tube and an aeration head; the aerator is arranged on the ground; the aeration tube is connected to the aerator, extends into the main well and is submerged into the area of the pollution plume; the aeration head is arranged in a part of the aeration tube which is submerged into the pollution plume, and is extracted out under the coverage of the inclined wells; the air extraction equipment comprises an air extractor and an air extraction pipeline; the air extractor is arranged on the ground; one end of the air extraction pipeline is connected to the air extractor, and the other end of the air extraction pipeline is connected with sub-air extraction pipelines going deep into the inclined wells. The aeration equipment is used for aerating air into the pollution plume, and groundwater volatile organic compounds are brought into the unsaturated zone along with the air. The air extraction equipment is used for extracting the volatile organic compounds from the ground surface, so that pollution gas staying in the unsaturated zone in a groundwater pollution remediation process can be effectively removed, and the remediation efficiency is increased.
