Abstract
The present invention discloses a nonhomogeneous soil pollutant multiphase extraction and tail gas purifying device and an application method thereof. The device comprises two water retaining walls, a water layer extraction system and a near-water soil layer extraction system, a nonhomogeneous soil layer extraction system and a geophysical prospecting system, etc. The distribution of pollutants and the range of the pollution plume can be determined through geophysical prospecting, borehole exploration, three-dimensional simulation, etc.; through the combined application of the water retaining wall and the water pumping and supplementing self-circulation system, it is beneficial to form a stable treatment area for the occurrence area of the groundwater layer; the arrangement of the water layer extraction system facilitates the liquid extraction of the organic pollutants in a free phase and a dissolved phase at the groundwater.
