The present invention relates to an anaerobic digestion facility including an internal circulation device to remove scum and increase digestion gas production. More specifically, the anaerobic digestion facility including an internal circulation device to remove scum and increase digestion gas production is capable of effectively removing scum generated at a gas-liquid boundary layer on an upper portion of the anaerobic digestion facility early, and activating the stirring of organic waste inside a digestion tube to increase the amount of digestion gas produced. Therefore, the anaerobic digestion facility of the present invention is configured to use a pump to transfer organic waste in a lower portion of an anaerobic digestion device to an upper portion of the same, in a process of making digestion gas by introducing organic waste into the anaerobic digestion device from the outside, to be re-injected and circulated, thus scum generated at the gas-liquid boundary layer inside the anaerobic digestion device can be dragged down into a liquid part of the anaerobic digestion device and removed; and digestion gas generated in the liquid part due to the removal of scum can be smoothly transferred to a gas part and discharged. |
