[Structure] A deodorizing method in which a chemical deodorant and a deodorizing microorganism and / or a deodorizing enzyme are used in combination to flow a deodorant liquid and a gas to be treated in countercurrent. As the chemical deodorant, a metal phthalocyanine derivative is preferably used. As the deodorizing microorganism, a bacterial mass, a mesophilic actinomycete, a yeast, a filamentous fungus, and a nodule fungus are mixed. The enzyme uses an oxidase. The composition of the deodorant solution is an aqueous solution or an aqueous dispersion solution containing 0.001 to 5.0% by weight of a chemical deodorant and 0.1 to 10% by weight of a deodorant microorganism and / or a deodorant enzyme. |
