Compact portable self-contained aerobic digestion toilet

An aerobic digestion toilet structure for purifying organic waste material dissolved or dispersed in water comprising:

• a toilet bowl;
• a main liquid-filled digestion chamber having vertical side walls said main digestion chamber being divided into first and second side-by-side portions by a vertical weir having an upper edge slightly below the liquid level in said chamber portions inlet means communicating with said first chamber portion for receiving organic waste from the bowl;
• a plurality of secondary liquid-filled digestion chambers surrounding the vertical side walls of said main chamber and forming therewith a unitary portable structure;
• means connecting said chambers in series such that a volume of waste added to said main chamber displaces liquid sequentially into the last downstream secondary chamber, said connecting means including between each two serially-connected chambers a quiescent chamber in which solids settle by gravity and means forming an overflow outlet from the respective quiescent chamber to the next downstream digestion chamber, the quiescent chamber associated with said main digestion chamber being in communication with said second chamber portion at a location remote from said weir;
• means for continuously mixing the contents of each digestion chamber to maintain any solids therein in suspension and for continuously aerating the contents of each chamber, said mixing and aerating means including air inlet means located adjacent the lower end of said weir and wherein said first and second chamber portions have bottom walls inclined downwardly toward the lower end of said weir to cause circulation of the liquid in each of said chamber portions in a direction upward along said weir, then away from said weir, then downwardly along respective chamber side walls and then toward said weir;
• and a pump carried by said unitary structure for pumping rinse liquid from one of the secondary chambers to said bowl.
