<p>PURPOSE: An anaerobic livestock waste treatment and a biogas production apparatus are provided to save water resources to treat livestock excretions and to produce bio gas which is an alternative fuel from the livestock excretions. CONSTITUTION: An anaerobic livestock waste treatment and biogas production apparatus comprises a raw water storage tank (10); an anaerobic reaction tank (20), an aeration tank (30); a settling tank (40); and a biogas storage tank (50). The aeration tank treats the livestock excretion (12) supplied from the anaerobic reaction tank by contacting a microorganism contact medium material (32) installed in an upper part. The settling tank treats livestock excretions (12) supplied from the aeration tank using gravels and sands. The biogas storage tank stores getting the biogas (54) as the biogas storage tank is connected to the anaerobic reaction tank, the aeration tank, and the settling tank.</p> |
