PURPOSE:To provide a deodorizing method for lowering running cost, simplifying a deodorizing apparatus or the maintenance thereof and generation no secondary pollution, constituted so as to deodorize malodorous gas by oxidizing and reducing the malodorous components in said gas through the gas-liquid contact of said malodorous gas with a culture solution of an aerobic or facultative anaerobic baceria group. CONSTITUTION:Malodorous component-containing gas is guided to the spray chamber 2 provided to the lower part of a deodorizing tower 1 by a blower 11 while a bacteria liquid 5 based on nitrate forming bacteria, nitrite forming bacteria and sulfur bacteria stored in a recirculation liquid tank 3 is sprayed from sprayers 7. The malodorous gas and the sprayed liquid are violently tumbled up and down using hollow balls 13 placed inside a guide plate 14 to enhance gas-liquid contact efficiency. The mist of the bacteria liquid accompanied by the gas after gas-liquid contact is caught by the packing material in a packing material chamber 4 and decomposition is performed by a small amount of the bacteria liquid flowed down from nozzles 8 and the bacteria group deposited on the packing material. The gas deodorized by oxidation a and reduction of malodorous components therein is exhausted from an exhaust port 12. A constant amount of the bacteria liquid is blown from a pipe 10 while a constant amount of water to be replenished is introduced from a pipe 9 to attain proper propagation of bacteria. |
