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). Sediment settled at the bottom of the respective sediment separation chambers is fed and stored in a sediment storage chamber (55).
