<p>PURPOSE: An anaerobic-aerobic composting facility is provided to minimize the generations of odors by inducing aerobic digestion, and maximize the effectiveness of stirring in a short time. CONSTITUTION: An anaerobic-aerobic composting facility includes an anaerobic bioreactor(1) and an aerobic bioreactor(2). The anaerobic bioreactor installed at an attic space collects a biogas with a collecting part. The aerobic bioreactor installed to be parallel to the anaerobic bioreactor is supplied with a part of fermented compost from the anaerobic bioreactor, and then mixes the compost with slurry stored inside using screw stirrers(4) for composting. The screw stirrers are coaxially installed in the anaerobic bioreactor and the aerobic bioreactor. One of the screw stirrers in the anaerobic bioreactor pumps pig slurry, and then directly injects the pig slurry inside the compost.</p> |
