<P>PROBLEM TO BE SOLVED: To provide an organic waste treatment apparatus reduced in a generating amount of residue, improved in methanation efficiency, and further capable of recovering even an inorganic material and metal. <P>SOLUTION: The organic waste treatment apparatus 1 includes: a fermentation tank 10 for generating a biogas containing methane and hydrogen sulfide by fermenting a solid organic waste SW; a biological desulfurization apparatus 20 for obtaining sulfuric acid from the hydrogen sulfide contained in the biogas; and a metal dissolution tank 40 for returning the residue of the solid organic waste SW generated in the fermentation tank 10 to the fermentation tank 10 by decomposing with the sulfuric acid obtained by the biochemical desulfurization apparatus 20. <P>COPYRIGHT: (C)2012,JPO&INPIT |
