Abstract: An apparatus for generating bio-gas from organic waste is provided to allow the organic waste to make contact with anaerobic microorganisms easily by adjusting the size of organic waste containing a large amount of solids, prevent wastewater from being generated in an organic waste treatment process, and improve anaerobic digestion efficiency by supplying high concentration microorganisms cultured in the organic waste treatment process into a dry anaerobic digestion tank. An apparatus for generating bio-gas from organic waste comprises: a crushing tank(10) in which organic waste is crushed; a screen equipment(20) for screening organic waste discharged from the crushing tank; a pre-treatment equipment(30) that is connected to the screen equipment, and includes a steam feeder(35); a mixing tank(40) for mixing microorganisms with organic waste that has flown into the mixing tank from the pre-treatment equipment; a dry anaerobic digestion tank(50) that is connected to the mixing tank, and includes an agitation equipment(55) and a microorganism feeder(85); a solid-liquid separator(70) for separating solids and liquid from organic waste discharged from the dry anaerobic digestion tank; a microorganism culture tank(80) for culturing liquid phase organic waste separated from the solid-liquid separator; and a bio-gas storage tank(90) for storing bio-gas generated from the dry anaerobic digestion tank. The microorganism culture tank is connected with the microorganism feeder through connecting pipe(86).
