NOVELTY - Waste treatment system comprises a waste separator (10), a water-permeable cylindrical sleeve (12) received in an outer box (11), a top plate (13) closing top openings of the outer box and sleeve, a rotary shaft (16) extending through the top plate into the sleeve, a rotary brush mounted on the rotary shaft, a closure mechanism closing the bottom opening of the space, and a drive unit.    USE - The system is used for separating human waste into solid and liquid parts for subsequent treatment e.g. microbial decomposition and/or activated sludge treatment. It is used for a temporary toilet.    DETAILED DESCRIPTION - Waste treatment system comprises a waste separator (10), a water-permeable cylindrical sleeve (12), a top plate (13), a vertical rotary shaft (16), a helical rotary brush (17), a closure mechanism (20) and a drive unit. The cylindrical sleeve is coaxially received in the outer box (11).    The top plate closes the top openings of the outer box and the cylindrical sleeve. The cylindrical sleeve has an open bottom. The rotary shaft coaxially extends through the plate into the cylindrical sleeve. The rotary brush is mounted on the rotary shaft. The top plate is formed with a port (21) through which waste is introduced into the cylindrical sleeve. The closure mechanism closes the bottom opening of the space defined between the outer box and the cylinder mechanism and formed with a discharge port. The drive unit rotates the rotary shaft and the brush, thus separating waste supplied into the cylinder mechanism into a liquid part which passes through the cylindrical sleeve into the space and is discharged through the discharge port. The solid part is moved down in the cylindrical sleeve by the brush and drops through the open bottom.    DESCRIPTION OF DRAWING(S) - The figure shows the system.
