摘要：
Provided is a water recovery system having a simple structure which is capable of treating water to be treated in a confined space such as a nuclear shelter or a space station. The wastewater treatment system includes a cation-exchange device 1 in which water to be treated, such as wastewater originating in a space station or the like, 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 2 in which organic substances, urea, and other nitrogen compounds contained in water discharged from the cation-exchange device 1 are decomposed; a catalytic decomposition device 3 in which the residual organic component is brought into contact with a catalyst to be decomposed; an electrodialysis device 4 in which water discharged from the catalytic decomposition device 3 is treated by electrodialysis to produce desalted water as well as an acid and an alkali; and a mineral adding device 5 in which a mineral is added to the desalted water.
