1. A preseparating toilet bowl for roughly separating the liquid waste and the toilet bowl rinsing water from the solid waste comprising in combination:

  • (a) a toilet bowl of a funnel-shaped tubular construction having a seat disposed at the diverging end of said toilet bowl;

    (b) a converging-diverging tubular bottom having a smooth throat section connected to the converging end of said toilet bowl in a smooth and continuous relationship and thus providing a diverging bottom for said toilet bowl;

    (c) a solid waste tube with an inlet diameter substantially greater than the diameter of said throat section of said converging-diverging tubular bottom and substantially less than the diameter of said diverging bottom of said toilet bowl, said solid waste tube disposed within said diverging bottom of said toilet bowl in a substantially coaxial relationship wherein an annular gap is provided intermediate said diverging bottom of said toilet bowl and said inlet of said solid waste tube; and

    (d) a liquid waste pipe for draining the liquid waste and the toilet rinse water collected at a closed bottom of said annular gap intermediate said diverging bottom of said toilet bowl and said solid waste tube;

    whereby, the liquid waste and the toilet bowl rinsing water landing on the inner wall of said funnel-shaped toilet bowl flows down following the wall of said converging-diverging tubular bottom of said toilet bowl due to surface tension and is discharged through said liquid waste tube, while the solid waste dropped into said toilet bowl is funneled through said throat of said converging-diverging tubular bottom of said toilet bowl and drops into said solid waste tube, said solid waste tube discharging the solid waste dropped thereinto.
