NOVELTY - A garbage treatment apparatus comprises a treatment bath (2) in a housing (1) and having a perforated plate; an agitator (3) in treatment bath to agitate garbage; a drain bath (4) disposed at a lower end of treatment bath and having an opening adjacent to an upper end to allow decomposed garbage in bath to be discharged to outside; a water supply pipe to supply water into the baths; and a re-supply pipe to resupply particulate garbage constituents back to treatment bath.    USE - For garbage treatment.    ADVANTAGE - The garbage treatment apparatus circulates and re-treats particulate garbage constituents contained and remaining un-decomposed in garbage primarily treated in the treatment bath, thereby maximizing garbage treatment efficiency. The garbage treatment apparatus circulates water supplied into the treatment bath and discharged through the drain bath, into the treatment bath so that the water can be reused, thereby reducing water consumption and ameliorating cost effectiveness of the garbage treatment apparatus. The garbage treatment apparatus allows microorganisms to be automatically fed into the treatment bath along with water supplied, thereby eliminating inconvenience and cumbersomeness, which can be otherwise caused by a manual feeding operation of the microorganisms. Since agitating blades to be coupled with an agitating shaft of an agitator are partially shaped in the form of bolts to be locked with nuts, assemblability of the apparatus is improved, deformation of the agitating shaft is prevented, and replacement of the agitating blades can be easily implemented. As the treatment bath nozzle pipe for supplying water into the treatment bath is positioned above the housing, the treatment bath nozzle pipe is prevented from being broken by interference with the agitating blades of the agitator. The garbage treatment apparatus in which a cover element made of urethane is fixed to a paddle provided to a distal end of each agitating blade constituting the agitator, thereby preventing a perforated plate from being damaged in the treatment bath while the agitator performs an agitating operation. Since particulate garbage constituents, which are contained and remaining un-decomposed in garbage primarily treated in the treatment bath, are circulated into and re-treated in the treatment bath so that the garbage can be completely decomposed, it is possible to eliminate subsequent processing operations for collecting and burying or burning the un-decomposed particulate garbage constituents, which is otherwise needed in the conventional art.    DETAILED DESCRIPTION - The apparatus further comprises a microorganism-feeding trough (14) at the upper end of the treatment bath to feed microorganisms along with the water supplied through the pipe; a heater (5) in the housing to keep temperature in treatment bath constant; and a controller (9) connected to an actuator, water supply pipe, re-supply pipe and the heater for controlling operation of the garbage treatment apparatus. The re-supply pipe extends between a lower portion of the drain bath and an upper portion of the treatment bath.
