Abstract

PURPOSE: To suppress the generation of ammonia by stirring garbage while kneading the same along with org. matter decomposing bacteria to prevent corrosion or to dispense with a deodorizing device and to prevent the deterioration of environment by recovering steam generated at the time of the decomposition of garbage to discharge the same. CONSTITUTION: When a drive device 18 is driven, a stirring blade element is rotated around the center 17 of rotation through a stirring shaft 10 to stirr the garbage thrown in a stirring chamber 5. When a useful bacteria group is thrown in the stirring chamber 5 at the same time, the garbage and the useful bacteria group are kneaded. At this time, since both first and second stirring blades 13,14 are inclined in mutually opposite directions in a predetermined direction with respect to the center 17 of rotation, the flow directions of garbage are different within the stirring chamber 5 and the useful bacteria group can be uniformly kneaded with the garbage. The drain water 31 in a treatment apparatus main body 2 is discharged from a discharge pipe 34 to be stored in a tank and subsequently introduced into a purifying column. The gas in the stirring chamber 5 rising within the purifying column is purified by drain water 31 to be discharged.
