PROBLEM TO BE SOLVED: To provide an anaerobic integration process apparatus for an organic waste treatment. SOLUTION: The apparatus includes a first solid-liquid separator which separates an organic waste into a liquid-phase waste and a solid-phase waste; an acid forming tank which decomposes the liquid-phase waster separated through the first solid-liquid separator by acid forming micro-organisms; a UASB reaction tank which decomposes the liquid-phase waste discharged from the acid forming tank by anaerobic micro-organisms; a crushing tank which crushes the solid-phase waste separated through the first solid-liquid separator into small pieces; a mixing tank which mixes the solid-phase waste crushed into small pieces through the crushing tank with micro-organisms; and a dry anaerobic tank which carries out a dry anaerobic treatment of the solid-phase waste mixed with the micro-organisms in the mixing tank. The integration process apparatus has environmentally friendly advantages such as carrying out wet and dry anaerobic treatments of the liquid-phase waste and the solid-phase waste respectively, improving the treatment efficiency by sharing the micro-organisms occurring in the treatment process, collecting biogases generated during the treatment and circulating the waste liquid and having an undischarge system.
