PROBLEM TO BE SOLVED: To provide a biological deodorization apparatus for preventing corrosion of a pipeline caused by sulfuric acid generated inside the processed gas pipeline.SOLUTION: A biological deodorization apparatus 10 includes: a biological deodorization tower 20 into which malodorous gas Gis introduced; and a carrier-filled layer 21 which is filled with a microorganism-retaining carrier and disposed inside the biological deodorization tower 20, and generates a processed gas Gby decomposing the malodorous gas G. In the biological deodorization tower 20, a first sprinkling unit 40 for sprinkling water toward the carrier-filled layer 21 is disposed. A processed gas pipeline 30 for exhausting the processed gas Gfrom the inside to the outside of the biological deodorization tower 20 is connected to the biological deodorization tower 20, and at least one part of the processed gas pipeline 30 is inclined to a horizontal plane.SELECTED DRAWING: Figure 1 |
