<p>PURPOSE:To attain cost reduction by providing and joining a cylindrical member on a base plate of case body so that the cylindrical member contacts the side wall of the case body at three positions in the inside of the case body of a methane fermentation apparatus. CONSTITUTION:Leftover rice or the like is introduced from an introduction cylinder 2. After the leftover rice is stored in a regulation vessel 4, it is sent to a fermentation vessel with a conveyer 5 and decomposed into gaseous methane, gaseous carbon dioxide and digested sludge. After the decomposed gaseous components are desulfurized by a desulfurizing agent 7 in a fermentation agas desulrizing vessel 6, these are separated from dew-condensed water and fed through a fermentation gas takeout port 10 to a fermentation gas consuming apparatus of external part. The digested sludge is fed by the quantity accordant with the introduced charge to an overflow vessel 12 from a fermentation vessel 3 and overflowed naturally from an overflow port 15 to a waste liquid treating apparatus at the external part.</p> |
