The apparatus for treating organic wastes comprising an acid fermentation tank 140, a methane fermentation tank 150, a concentration tank 300 and a separation membrane apparatus 400 according to the present invention is characterized in that in the acid fermentation tank 140, A first circulation line 143 in which a first circulation pump 143a is connected to the methane fermentation tank 150 so that a part of the first circulation pump 143a is supplied to the methane fermentation tank 150; And a second circulation line (230) in which a second circulation pump (231) is connected so that a part of the anaerobic digestion liquid in the methane fermentation tank (150) is supplied to the acid fermentation tank (140); Wherein the concentrating tank 300 is installed between the methane fermentation tank 150 and the separation membrane apparatus 400 and receives the concentrated circulation water from the separation membrane apparatus 400, The methane fermentation tank 150 is indirectly injected into the methane fermentation tank 150 to completely remove the odor generated during the anaerobic digestion liquid treatment. By automating the entire facility, labor and maintenance costs can be saved. |
