Document Type and Number:
Japanese Patent JP6565170
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To efficiently treat waste water including scale components, organic matters, inorganic ions, particularly, waste water such as human body exhaust water and living waste water produced in closed system spaces such as nuclear shelters, disaster shelters, space stations, manned spacecraft for a Moon/Mars mission, lunar surface matrix or the like by a device with a simple constitution, and to recover water.SOLUTION: Hardness components are removed by a softening apparatus 1 from the water to be treated such as hyman body exhaust water, softening treated water and electrolyzing treated water are heat-exchanged by a heat exchanger 2, and thereafter, in a high temperature-high pressure electrolyzer 3, by electrolyzing under high temperature high pressure, organic matter, urea, ammonia or the like are decomposed away. After the electrolyzing treated water is subjected to degassing treatment by a degassing membrane apparatus 4, and thereafter, desalting treatment is performed by electrodialyzers 10, 20 for producing acid-alkali provided in series to two steps.SELECTED DRAWING: Figure 1
