Abstract: Wastewater containing scale components, organic substances, inorganic ions, and the like, such as human effluent, generated in a closed system space, such as a nuclear shelter, a hazardous shelter, a space station or a moon-Mars mission manned spacecraft, or a lunar base is efficiently treated by a simple structural apparatus, so that water is recovered. After a hardness component is removed from water to be treated, such as human effluent, by a softening device, and heat exchange is performed between softening treated water and electrolysis treated water by a heat exchanger, by a high-temperature and high-pressure electrolysis device, organic substances, urea, ammonia, and the like are removed by electrolysis performed under high-temperature and high-pressure conditions. After the electrolysis treated water is processed by a deaeration treatment using a deaeration membrane device, a desalting treatment is performed by acid/alkali manufacturing electrodialysis devices and provided in series at two stages.

Abstract: Oxygen permeable membrane modules are provided in a reactor in multiple stages. An oxygen-containing gas from a blower B is sequentially circulated through the oxygen permeable membrane modules via pipes and is discharged from a pipe. Raw water flows out into a bottom part of the reactor through a plurality of nozzles, and a fluidized bed F of a biological carrier such as activated carbon is formed inside the reactor. Treated water flows out of a trough via an outflow port.

Abstract: Wastewater such as water discharged by the human body and domestic wastewater which is produced in a confined space, can be treated and recovered with efficiency by using a simple apparatus. Specifically, hardness components of water-to-be-treated are removed with a softening apparatus. Subsequently, electrolysis is performed with a high-temperature high-pressure electrolysis apparatus in order to decompose and remove organic substances, urea, ammonia, and the like. The electrolyzed water is desalinated with a desalination electrodialysis apparatus in order to produce product water and a salt-concentrated liquid. The salt-concentrated liquid is further treated with an acid-alkali production electrodialysis apparatus in order to produce desalinated water, an acid solution, and an alkali solution. The acid solution is used as an agent for regenerating the softening apparatus. The alkali solution is used as an agent for converting the softening apparatus into Na-type. The desalinated water is treated with the desalination electrodialysis apparatus.
