<p>Disclosed herein is an anaerobic digester. More specifically, disclosed is an apartment-shaped anaerobic digester configured to include a first input reactor 3 into which livestock wastewater or food waste (hereinafter, 'inflow') is introduced; a second input reactor 4 into which the inflow passing through the first input reactor is introduced; a first region 5, a second region 6, a third region 7, and a fourth region 8 of an anaerobic digestion reactor designed for the inflow passing through the second input reactor 4 to perform methane fermentation in a first-in and first-out order to produce and transfer biogas simultaneously into the next anaerobic digestion region; an inlet pipe 41 in a lower layer portion of the fourth region 8 of the anaerobic digestion reactor, into which sludge liquid is drawn in from the lower layer; an inlet pipe 42 in an upper layer portion of the forth region of the anaerobic digestion reactor, into which activated liquid is drawn in from the upper layer; a biogas capturing device which is connected to a gas layer in the fourth region 8 of the anaerobic digestion reactor; a first heat exchange 2 tube provided inside the first input reactor 3 to allow the sludge liquid drawn in from the inlet pipe 41 in the lower layer portion to perform heat exchange with a new inflow; a first region 11, a second region 12, a third region 13, and a fourth region 14 of a subsequent treatment reactor provided on the upper layer of the anaerobic digestion reactor, to allow the sludge liquid whose heat exchange is completed to be introduced in a first-in and first-out order, and to treat gas odor components generated from the sludge liquid; and a liquid-composting reactor in which the emitted sludge whose odor components have been removed is stored.</p> |
