To dispense with the replacement of a decomposing medium material semi- permanently in an odorless state by mounting sirring blades on a stirring shaft and providing a water distributing pipe to the bottom part of a treatment tank and providing an overflow pipe to the upper part thereof while packing the treatment tank with a decomposing medium material for fermentative decomposition treatment and underwater decomposition treatment.
Crushed org. matter flows in a treatment tank 1 to be stirred along with a decomposing medium material for fermentative decomposition treatment and underwater decomposition treatment by a stirring shaft 11 and stirring blades 12 stirring the org. matter in cooperation with the operation of a water adding crushing disposer 27. In the case of fermentative decomposition treatment, the org. waste crushed by the net of a drain port 13 and crushing water are separated and filtered and only the crushing water is discharged from a water distributing pipe 13. In the case of underwater decomposition treatment, the water distributing pipe 13 is blocked by a valve and the excessive water flowing in the treatment tank 1 is discharged out of the treatment tank 1 from an overflow pipe 14. By this constitution, the troublesomeness such as the replacement of the decomposing medium is eliminated.
