PROBLEM TO BE SOLVED: To improve the decomposition capability by preventing the closure of the aeration holes of bubbler diffusers even in a high-concn. liquid for decomposing garbage in hot water by aerobic microorganisms, obviating the emission of the froth and waste water generated in a decomposition vessel to the outside of the machine and further surely separating the concd. and treated water emitted from the decomposition vessel. SOLUTION: The inside of the base of the decomposition vessel 2 provided with heating means is provided with the bubbler diffusers 1 formed by inserting upper and lower bubble generating surface plates which are formed to an approximately truncated conical shape and are curvilinearly provided with bubble generating vibration surfaces at the outer periphery peripheral edges into the bubbler core pipe and superposing above and below. The device is provided with a defoaming gas-water separator 18 provided with the ceiling cap of the decomposition vessel 2, rotary vane plates rotating by having small spacings and a discharge port. A thickening and separating cyclone 32 which is provided with a separated water take- out cylindrical within the upper half part of the cylindrical body, is provided with a low sp. gr. riser inserted therein and is provided with a low sp. gr. take-out pipe and a heavy sp. gr. take-out pipe at the top and bottom ends of the cylindrical body is arranged in a thickening treatment feeding line between the decomposition vessel 2 and an evaporation solidification vessel 45. The discharge pipe 50 of the evaporation solidification vessel 45 is branched and provided with a vent pipe 55 communicating with the decomposition vessel 2 to return the waste heat.
