    摘要： The present invention relates to a system capable of maximizing biogas production by mixing dry feed at a predetermined ratio with digestive fluid discharged from an anaerobic digestion tank, which is a front-end process of a wastewater treatment system, and then introducing it into a digestion tank. The present invention implements a new type of system which separates the digestive fluid discharged from an anaerobic digestion tank, which is a front-end process of the wastewater treatment system, into solid and liquid in a sedimentation tank, and then mixes treated water with dry feed at a predetermined ratio and reintroduces it into the digestion tank, and also introduces digested slime and sludge into dryer equipment, thereby providing a system for producing biogas using a mixed liquid of digestive fluid treated water and dry feed that can maximize the production of biogas (methane gas) to reduce energy costs, increase the production of dry substances to reduce waste disposal costs, and increase the resource recycling rate.
