Abstract

A waste disposal system separates human wastes into solid and liquid parts for subsequent treatment such as microbial decomposition treatment and/or activated sludge treatment. The system includes an outer box. A cylindrical member made of a water-permeable material is received in the outer box. A top plate closes the top openings of the outer box and the cylindrical member. The latter has an open bottom. A helical rotary brush is mounted on a vertical rotary shaft extending through the top plate into the cylindrical member so as to be coaxially received in the cylindrical member. The top plate is formed with a port through which waste is adapted to be introduced into the cylindrical member. A closure member closes the bottom opening of the space defined between the outer box and the cylindrical member and is formed with a discharge port.

Dependent claims

A waste treatment system comprising a waste separator comprising an outer box, a cylindrical member made of a water-permeable material and coaxially received in said outer box, a top plate closing the top openings of said outer box and said cylindrical member, said cylindrical member having an open bottom, a vertical rotary shaft coaxially extending through said top plate into said cylindrical member, a helical rotary brush mounted on said vertical rotary shaft, said top plate being formed with a port through which waste is introduced into said cylindrical member, a closure member for closing the bottom opening of the space defined between said outer box and said cylindrical member and formed with a discharge port, and a drive unit for rotating said rotary shaft and said brush, whereby separating waste supplied into said cylindrical member is separated into a liquid part, which passes through said cylindrical member into said space and is discharged through said discharge port, and a solid part, which is moved down in said cylindrical member by said brush and drops through said open bottom.
