NOVELTY - A deodorizing chamber (B) has main deodorizing layer (2) arranged in vertical cylinder (11) and has supplement layers (3a,3b). A deodorant liquid sprinkling pipe (15) is linked to a deodorant liquid supply pipe (14). Magnetic shields (6b,6a) are provided respectively in the upper ends of the supply pipe and deodorant liquid introduction device (7).    USE - For manure manufacturing apparatus which manufactures manure using livestock excrement such as faeces of pig, cattle, hen, for growth of vegetables, trees, shrubs.    ADVANTAGE - Use of deodorant introduction device enables enhancing deodorization of offensive gases. Operation of process equipment becomes easy and maintenance is reduced. Since the microbes and the deodorant liquid are efficiently arranged in a vertical, cylindrical filler, contact of process gas to the microbes and the deodorant liquid is enhanced. Hence decomposition of offensive odor from the process gas is done reliably. Deodorizing efficiency is improved because the process gas passes through the cylinders arranged in stages. Since the magnetic treatment device is arranged in the upper ends of the deodorant liquid introduction device and of the supply pipe, offensive smell of process gas is reduced. Since the magnetic treatment device atomizes the deodorant liquid, deodorizing efficiency is increased.    DETAILED DESCRIPTION - The deodorant liquid supply pipe extending from a deodorizing bath (9) to a gas emission chamber (C) is connected with a submersible pump (13). A process gas introduction chamber (A) is provided below the deodorization chamber. Deodorant introduction device is connected to the gas introduction chamber. The deodorant supply pipe supplies deodorant from the bath to the sprinkling pipe.    DESCRIPTION OF DRAWING(S) - The figure shows explanatory view of the deodorizer.
