초록 ▼

A self-contained toilet and sanitary waste treatment plant that has a delivery system, a biological treatment system and a water recovery system. The delivery system includes a vacuum-type flush toilet adapted to receive flush water from the water recovery system and delivery means adapted to discharge the sanitary waste and flush water into the biological treatment system. The latter includes anaerobic digestion means, aerobic digestion means and sedimentation means for reducing the organic matter by biological treatment. The effluent from the biological treatment system is discharged to the water recovery system wherein primary and secondary filtration means are employed for reclaiming water for flush or other purposes. The primary filtration means includes ultra-filtration apparatus for separation of the effluent into a water permeate and an effluent concentrate, the former passing to the secondary filtration means for further filtration treatment and storage as flush water, and the latter passing back to the biological treatment system for further reduction by biological treatment. Controls are provided to enable the waste treatment plant to operate automatically for extended periods of time.

대표청구항 ▼

A water-recycling sanitary waste treatment plant comprising a delivery system, a biological treatment system and a water recovery system; said delivery system including a flush-type toilet with a demand actuator and a bowl in which sanitary waste can be deposited, flush water supply means for transferring clear water from the water recovery system to the delivery system and for supplying the clear water as flush water under pressure to said bowl upon activation of said demand actuator, and delivery means for delivering the flush water and sanitary waste to said biological treatment system in response to activation of said demand actuator; said biological treatment system including apparatus for reducing biologically the sanitary waste received from the delivery system and discharging an effluent to said water recovery system; and, said water recovery system including ultrafiltration means for separation of said effluent into a water permeate and an effluent concentrate, said ultrafiltration means having a semipermeable tubular membrane into one end of which said effluent is introduced axially at a first pressure and from the other end of which said effluent concentrate is discharged, and a permeate collector tube that surrounds said tubular membrane for collecting at a lower second pressure permeate that passes radially through the membrane, recirculation means including a pump means for returning a portion of said effluent concentrate to said biological treatment system and for returning the remainder of said effluent concentrate at said first pressure to said ultrafiltration means for further separation into water permeate and effluent concentrate, water storage means, a secondary filtration means for receiving and polishing said water permeate, said secondary filtration means being in communication with said ultrafiltration means so that said permeate can be discharged at said second pressure from said ultrafiltration means to said secondary filtration means to be polished and discharged to said water storage means as clear water, and said water storage means being in communication with said delivery system for transfer thereto of the clear water by said flush water supply means.
