摘要:
A waste disposal system includes three interconnected tanks. Waste material is subjected to anaerobic bacterial action in a first tank and then transferred to a second tank. The waste material is subjected to aerobic bacterial action in the second tank and is then transferred to the third tank. The waste material may be subjected to action of a treating agent in the third tank.

Night soil is discharged to mixing chamber 11 containing liquid and comminuted by action of jets 23 and cutters 21. The mixture is aerated by source 13 flows to settlement chamber 6 where the heavier sludge is returned to conditioning chamber 5 for secondary aerobic digestion while the upper portion eventually overflows to chamber 10 for discharge.

An outdoor toilet system is provided with a mechanism for agitating solid waste material accumulating in a collection container, to reduce the volume of material. The agitator mechanism has a linkage connected to the door of the enclosure in which the toilet is located, such that the agitator mechanism is operated each time the door is opened and closed. The agitator mechanism can be a mechanical agitator or an air jet mechanism.

A composting toilet includes a tank (1) that is mounted so as to be inclined and rotatable about its longitudinal axis of symmetry (x-x'), which axis forms with the horizontal plane an angle (.alpha.) at least equal to 15.degree.. The toilet includes a seat (22) having an associated discharge hole (23). The entire discharge hole (23) is located directly vertically above a receiving orifice (6) of the tank.

A system and method is disclosed for composting feces and treating. Human feces is collected within a composting retainer and exposed to sufficient air and water to allow the feces to compost, thereby forming compost product. Urine is collected within an urine treatment retainer which is at least partially partitioned from the composting retainer and wherein the urine is passed through a substrate supporting aerobic nitrifying bacteria, thereby nitrifying a significant portion of the ammonium ions in the urine to form liquid product. The compost product is suitable for subsequent use, such as fertilizer or for use in forming a mixture with soil to form topsoil.

There is an emptying opening (18) at a given height on one side of the bottom (29) of the composting chamber (20) in a decomposition latrine with a rotatable stirring means (26a). In normal stirring, the means rotates for moving material away from the opening, and in emptying, the direction of rotation is reversed so that material may be discharged through the opening. The stirring means comprises six to twelve stirring members in the form of flat, bar-like members (50) extending between the end walls (11, 34) of the chamber (20).
摘要:
A decomposition latrine has a chamber (20) in which decomposable material (27) is heated with the help of a heat source (28) to a temperature in the range of 45.degree.-80.degree. C., the attainment of a rapid thermophilic decomposition process with simultaneous pasteurization of the material thus being enabled before the material is removed from the chamber. The pasteurized portion of the mass is movable away from the region at the heat source with the help of a stirrer (26), rotatable by means of an electric motor.

The disclosed invention is a continuous bioconverter or dry closet and method capable of aerobically and bacteriologically converting human and other organic wastes to principally carbon dioxide and water vapor. The closet comprises a collecting vessel containing a medium suitable for supporting aerobic decomposition. In accordance with the invention, the decomposition is a substantially total conversion of organic wastes to gases. In a preferred embodiment in the closet are two parallel shafts, each supporting a rotationally mounted pair of opposing auger-type blades (see FIGS. 1, 2 and 3) which provide a most efficient stirring action, resulting in a complete and continuous aeration (oxidation) of the aerobic bacteria in the chemically reactive organic mixture. Also disclosed are modifications of the basic design wherein (a) an electric motor rotates the augers and is mounted within the collecting vessel; (b) an aerator is placed in the bottom of the collecting vessel; and (c) a vapor condenser is made a part of the exhaust system, all of which yield novel advantages discussed in the specification. In the method, wastes are introduced to the medium and continuously agitated and supplied with oxygen from the time of their introduction and for the duration of the biconversion reaction.
