<p>PROBLEM TO BE SOLVED: To provide a treating device which can be easily maintained in a satisfactory operating state and treat a digestive gas economically without the use of a chemical or a dry desulfurization device, as well as a method for treating the digestive gas. SOLUTION: An aeration tank B is arranged right below a water wash desulfurization/decarbonation device A, and a biodesulfurization device C is arranged in a process line following the aeration tank B. The water wash desulfuriz ation/ decarbonation device A has an exhaust aperture 6 on the top and an air inlet 5 and a water drain port 10 at the bottom with a filled layer 2 for bringing air into contact with a liquid formed in the intermediate part. A water spray pipe 3 is installed between the filled layer 2 and the exhaust aperture 6. The water wash desulfurization/ decarbonation device A is connected to the aeration tank B with a water spray pipe 4. In addition, the aeration tank B has an air diffuser 12 provided at the bottom part and at the same time, an exhaust aperture 16 at the top, and the exhaust aperture 16 is connected to the biodesulfurization device C with a tubular path 25. Further, in the biodesulfurization device C, filled layers 18, 22 in which a filler with implanted microbes is packed, are arranged and an exhaust aperture 30 connected to a suction blower 33 is arranged at the bottom part.</p> |
