A method and a device for decontaminating contaminated soil masses, comprising a soil pile (H1) processed for biological degradation, wherein the pile has disposed therein perforated pipes (1), a main pipeline (10) to which the perforated pipes (1) are connected, a medium directing element (30) which includes an air transportation element (31) driven by a motor (51), wherein the pressure side (41) of the medium directing element (30) is connected to the main pipe (10), wherein the air transportation element (31) is adapted to aerate the soil pile (H 1) via the main pipe (10) and the perforated pipes (1) so as to accelerate the biological degradation process, wherein a second soil pile (H2) separated from the first soil pile (H 1) and processed for biological degradation is provided with perforated pipes (1) which are connected to the suction side (42) of the medium directing element (30) via a second main pipe (20), wherein the pressure side (41) and the suction side (42) of the medium directing element (30) are adapted to change places so as to achieve alternating aeration and therewith alternating heating of the two soil piles (H1, H2). |
