<p>PURPOSE:To improve recovery of methane gas by arranging a desulfurizer and a device for supplying a treated liquid. CONSTITUTION:In an apparatus, which consists of an organic acid fermenter 1, a desulfurizer 2 and a methane fermenter 3, a treated liquid out of the organic acid fermenter 1 is led to the desulfurizer, wherein hydrogen sulfide is physically removed, and then supplied to the methane fermenter 3, so that a generation efficiency of methane is improved.</p> |
