摘要： An aerobic sewage treatment system is constructed of a plurality of series-connected turbulent, aerated stages which progressively purify the waste to essentially organic-free water without building up sludge. The system is especially suitable for a compact toilet, such as a toilet on a pleasure boat or recreational vehicle. Discharge of effluent can be avoided by evaporation of water from the system by venting the stages and if necessary by heating the effluent from the last stage.

摘要： A plumbing system for flushing a toilet bowl is provided having one or more high pressure nozzles disposed about the rim of the bowl so that the discharge from the nozzles will impinge upon all of the interior surfaces of the bowl; the nozzles are each connected to a common pressure chamber through a flush valve; the pressure chamber contains an air pocket which will be compressed when liquid under main pressure accumulates in the pressure chamber; liquid from a water main is supplied to the pressure chamber through an adjustable flow restrictor so that, when the flush valve is open and water from the pressure chamber is discharged under pressure through the nozzles, a subsequent flushing cycle will be delayed until a predetermined line pressure builds up in the pressure chamber; a reservoir tank is connected to the bowl drain and is adapted to collect water from other utility stations until a predetermined quantity of liquid is present in the reservoir; control means are provided to discharge liquid from the reservoir to flush the drain conduit when the predetermined liquid level in the reservoir is reached.
