Title:
Soil purifying facility
Document Type and Number:
Japanese Patent JP6183913
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus for purifying soil, in which a problem of foul smell is solved in bioremediation for purifying oil-containing soil by microorganisms.SOLUTION: An apparatus 1 for purifying soil includes a purification body part 2, an air supply system 3 and an exhaust system 5. The purification body part 2 includes a plurality of septic tanks 2a. Microorganism-introduced oil-containing soil is housed in each of the septic tanks 2a. Air is supplied to the oil-containing soil of each of the septic tanks 2a from the air supply system 3. An opening 2c of each of the septic tanks 2a is closed by a top cover 2b. Gas in the space R formed in the upper part of each of the septic tanks 2a is discharged to the outside by the exhaust system 5. An adsorption column 5c is connected to the exhaust system 5 so that foul smell substances in the gas in the space R of each of the septic tanks 2a are adsorbed. As a result, the problem of foul smell in the bioremediation for purifying the soil can be solved.
