GARBAGE DISPOSAL DEVICE

PROBLEM TO BE SOLVED: To enable garbage to be decomposed in a short time with the help of microorganisms and scale down a treatment tank by providing the garbage receiving side with a grinding device and disposing a microorganism treatment device below the delivery aperture of the grinding device, in a run-off treatment device which runs off garbage into a sewerage after the garbage is crushed by a disposer or a crushing machine. SOLUTION: The garbage disposal device is equipped with a grinding device 20 disposed in the preceding stage is further constituted of a pressing part 25 for pressing garbage which is crushed by a disposer or a crushing machine and charged from a charge aperture 23, a disk part 30 for grinding the garbage and a drive part 50 for driving the disk part 30 through a joint part 40. Further, the garbage pushed in from the charging aperture 23 is ground by a rotating blade 29 in the disk part 25 and then is discharged from a discharge aperture 49. A microorganism treatment device 80 is connected to the discharge aperture 49 of the grinding device 20. Thus drain received from the discharge aperture 49 is caused to flow through a hydrophobic tank 81, a first and a second hydrophilic tank 82, 83 and a precipitation tank 84 and consequently, the organic content is completely decomposed and cleaned.
