    摘要: A portable toilet facility includes a plurality of seriesconnected aerobic digestion tanks within a walled enclosure. Venting of the air spaces of the tanks is accomplished with a vane-type air scoop which faces into the wind and conducts air to one of the air spaces, an exhaust vent conduit extending from one of the other air spaces to the exterior of the enclosure.

    摘要: An aerobic sewage treatment system includes a plurality of series-connected aerated digestion chambers. In order to prevent passage of solids from one chamber to the next downstream chamber the liquid connection between the chambers is formed by a specially shaped conduit having an open inlet end disposed within a quiet portion of its respective chamber.
