    Abstract: A toilet housing and waste collection and treatment system purify wastewater to a satisfactory level. When solid wastes are conveyed from individual toilets (31)-(33) into an active circulation chamber (16) in a toilet housing (10), the solid wastes are subjected to air exposure treatments in the active circulation chamber (16). The wastewater exposed to air in the active circulation chamber (16) is then purified through a three-phase flowing structure in first and second active water chambers (51) and (52), with the three-phase flowing structure including water, air, and carrier particles containing aerobic microorganisms. The wastewater so treated flows into first and second sediment separation chambers (53) and (54) where solid wastes are settled down and separated from the wastewater. The treated water is then supplied to a water reservoir (56) which in turns supplies the water to the respective toilets (31)-(33).

Basically, the toilet includes a bowl, a seat partially covering the bowl opening and a lid movable between a raised position exposing the seat and a lower position covering the seat sealing the bowl. When the lid is raised, an air extraction system removes air and odors from the bowl. After use, the lid is either manually or automatically closed, initiating a high or low flush. When left to close automatically a low flush only is initiated. In a low flush, water is directed under pressure through two rotating spray jets against the bowl interior, then is removed along with any toilet contents by the rotating jets action and the macerator which reduces solids to small particles. Heated air is then directed into the bowl to dry the bowl. In a high flush, an additional spray jet cleans the seat and a larger quantity (typically 1/3 additional) of water is used.

  • Patent number: 4115876
    Abstract: This disclosure relates to a self-contained recirculating toilet system which includes a toilet bowl having a built-in flush pump and a waste-discharge macerator pump with the discharge of the macerator pump being connected to a holding tank unit for delivering raw waste into a raw-waste compartment thereof. The raw waste is periodically pumped from the raw-waste compartment to a combined sterilization and flocculation cell unit after which the treated liquid is returned to the holding-tank unit and after solids float over weir by virtue of gaseous suspension from the treatment in the cells and aided by the outward flow through a discharge slit the remaining clarified and sterilized liquid is directed into a flush-water compartment of the holding-tank unit for use in the next flushing of the toilet. The system provides for repeated use of the same water for multiple toilet flushing.
