A holding tank for a sanitary installation carrying a sanitary fixture receives fecal matter or wastewater from the sanitary fixture of the sanitary installation and has at least one inlet and at least one outlet. At least one suction float in the holding tank floats on the liquid therein and forms with at least one suction chamber opening downward through a suction screen into the tank. An extraction line connected to at least one suction pump opens into the liquid in the suction chamber for withdrawing the liquid from the holding tank through the suction float and for recycling the extracted water for use as a flushing fluid for the sanitary fixture of the sanitary installation.

The present invention aims for providing an excrement treatment device capable of directly discharging sewage in a sewage tank to the outside sewers by a compressed air supplied from the excrement treatment device. The present invention includes a step of opening a suction port of a suction valve 44 of a sewage tank 19 and closing a water discharge valve 46 of the sewage tank 19; a step of sucking air in the sewage tank 19 from an air inlet/outlet 45 of the sewage tank 19 and sucking a sewage from a pipe connected to a suction port of the suction valve 44 to store the sewage; a step of closing the suction port of the suction valve 44 of the sewage tank 19 and opening the water discharge valve 46 of the sewage tank 19; and a step of injecting a compressed air into the air inlet/outlet of the sewage tank 19 to discharge the stored sewage to an outside from the water discharge valve 46.

A housing for a portable sanitary fixture having at least one floor part, at least one roof part, a plurality of side walls, and a plurality of support posts. The floor part is connected to the roof part and/or at least two side walls to each other via at least one support post. The housing has at least three, preferably at least four, and preferably four support posts of which at least one is hollow, and at least one electrically operated functional device or at least one part of at least one electrically operated functional unit is held in an interior of the support post.

The present invention includes a toilet pool, wherein the toilet pool has a pool tapered from top to bottom, the bottom of the pool is a discharge outlet, the top of the pool is a tapered annular platform, the tapered annular platform consists of a wide part and a narrow part, above the tapered annular platform is a slot flush nozzle, shunts implemented by the slot flush nozzle are evenly distributed on a surface of the pool under the guide of the tapered annular platform, and the toilet pool is provided with a clean water supply. It achieves a configuration that two flushing systems coexist on a toilet pool, achieves secondary homogenization of water currents, achieves water-saving and efficient flushing, achieves maximization of water capacity in the same space, and achieves a simple, reliable fixedly-installed toilet.

Various aspects of this disclosure relate to toilet systems that include compositions to inhibit wastewater from freezing in a waste tank of a toilet. A first fluid treatment composition comprises a salt that is introduced into the waste tank. A second fluid treatment composition is a solid composite that also comprises a salt and that is introduced into a urinal in fluid communication with the waste tank.
