NOVELTY - A garbage treatment apparatus comprising inorganic balls and garbage stored in a container agitated by a propeller assembly during rotation of a shaft and moved downward at a central portion of the container to flow upward along a flow adjustment plate and an inner peripheral wall of the container, is new.    USE - For treating garbage.    ADVANTAGE - The garbage and inorganic balls are uniformly mixed without crushing die inorganic balls during treatment of the garbage. The residual sludge adhered to the inorganic balls can be removed by washing in a simple manner after treatment of the garbage.    DETAILED DESCRIPTION - A garbage treatment apparatus comprising a cylindrical container (10) to store porous inorganic balls containing microorganism for decomposition of garbage and to store garbage to be treated, a rotation shaft (50) vertically mounted for rotary movement in a central portion of the container, a driving mechanism (34) mounted on the container for driving the shaft, a screw propeller assembly mounted to a lower portion of the shaft to feed downward the inorganic balls and garbage stored in the container, a flow adjustment plate (21) in the form of a truncated conical plate mounted in a bottom portion of the container concentrically with the rotation shaft and placed in an upwardly expanded condition, and a rotary disk (51, 54) horizontally mounted to a lower end of the shaft and placed under the propeller assembly. The rotary disk is coupled with the flow adjustment plate to close a lower end opening of the adjustment plate and rotatable relative to the adjustment plate. The inorganic balls and garbage stored in the container are agitated by the propeller assembly during rotation of the shaft and moved downward at the central portion of the container to flow upward along the adjustment plate and the inner peripheral wall of the container.
