ABSTRACT:
The device for the disposal of sanitary waste consists of a fixed drum-type container (20) with a horizontal central axis (MA) and with inlet pipes for dosed wash liquid (WF), for sanitary liquid (HF) and for dosed chemicals (CH), whereby a discharge duct (65) for the carrying-off of the comminuted sanitary waste interspersed with wash liquid from the bottom area of the container (20) is provided in the bottom area of the container (20), in the inner space (27) of which a knife disk (30) which can be rotatably driven is placed in the area of one of its both vertical front walls (21; 22) with shearing knives (31) turned to the inner space (27) of the container (20), whereby an ascendingly guided compressor screw (60) follows the conveyor screw (65), compressor screw which forms with a shear sieve sheet (70) a functional unit for separating the comminuted sanitary waste containing solid components from the wash liquid (WF) with the constituents of the sanitary waste which are dissolved therein and the wash liquid is supplied to a drain (85) over a discharge duct (80), whereby the rest of the comminuted sanitary waste freed from the liquid and containing solid constituents is fed in the upper area (61b) of the housing (61) to a collecting container (95).
