To provide a methane fermentation apparatus which is used for methane-fermenting a raw material such as livestock excreta and garbage by an anaerobic microbe and in which a bad smell, which is generated since aerobic fermentation is caused when organic waste being the raw material is received and warmed and an acid is produced, is prevented from being generated and functions of methane fermentation, desulfurization and gas storage are integrated so that the raw material can be methane-fermented at a low cost.
The methane fermentation apparatus is disposed with a three-ply cylinder on the same axis. A raw material warming part, an acid producing part and a methane fermentation part are formed in the three-ply cylinder in this order from the center of the three-ply cylinder. The apparatus installs a desulfurization part in the upper part of the three-ply cylinder to remove a malodorous component in the aerobic biogas produced in the raw material warming part and the acid producing part and hydrogen sulfide (H
