PROBLEM TO BE SOLVED: To provide a polluted soil purifier with which offensive odor diffusion is prevented and with which air sufficient for activating the function of microorganisms in microorganism-containing polluted soil can be supplied to the microorganisms in the microorganism-containing polluted soil.SOLUTION: A polluted soil purifier 1, which purifies polluted soil by supplying air to microorganisms in microorganism-containing polluted soil formed by mixing the polluted soil and aerobic microorganisms decomposing a pollution substance in the polluted soil, includes: an air-permeable cover member (a sheet 2) which covers banked microorganism-containing polluted soil (a bio-pile 50); a perforated pipe 4 which is equipped with through holes 41 passing through the inside and outside of the pipe and which is inserted into the microorganism-containing polluted soil; suction means (a pump 3) which supplies air outside the cover member to the microorganism-containing polluted soil via the cover member by being linked to an end of the perforated pipe 4 and sucking air inside the pipe; and deodorizing means (a deodorizing device 5) which deodorizes air sucked with the suction means and exhausts the deodorized air. |
