<p>PURPOSE:To efficiently eliminate the odor by spraying a biochemically treated water of a waste water on a filler layer. CONSTITUTION:Peat fibers are packed in a biochemical deodorizing column 1 to form a peat layer 2. The odor is introduced in the biochemical deodorizing column 1 from a gas inlet pipe 3, is decomposed by a micro-organism in the peat layer 2, and the deodorized gas is flowed out from the pipe 4. The biochemically treated water of the waste water is fed from the pipe 5 and sprayed from a water spraying pipe 6; thus the treated water is supplied to the filler layer; and simultaneously the decomposition product or the reaction product accumulated in the layer are washed away from the pipe 7 out of the column. Hence, the activity of the living micro-organism is maintained thereby.</p> |
