Abstract |
AB |
[EN] A water recovery system can treat water in a confined space. The wastewater treatment system includes a cation-exchange device in which water to be treated, such as wastewater originating in a space station, water discharged by the human body, water produced by condensing water vapor contained in the air, is directly introduced to a cation-exchange resin and thereby treated by cation exchange; a diamond-electrode electrolysis device in which organic substances, urea, and other nitrogen compounds contained in water discharged from the cation-exchange device are decomposed; a catalytic decomposition device in which the residual organic component is brought into contact with a catalyst to be decomposed; an electrodialysis device in which water discharged from the catalytic decomposition device is treated by electrodialysis to produce desalted water as well as an acid and an alkali; and a mineral adding device in which a mineral is added to the desalted water. |
