PURPOSE:To purify water and to use the purified water as drinking water, domestic water, cultivation water, etc., by treating the waste water generated from breeding and cultivating devices, etc., in the closed system of a spacecraft, etc., with an org. material removing apparatus using activated carbon, etc., and then treating the water with a hydrophobic porous membrane. CONSTITUTION:Waste water generated from a human life and devices for breeding and cultivating animals and plants in the closed space of spacecrafts, submarines, etc., is treated with an org. material removing apparatus 2 using activated carbon, etc., and then treated with a hydrophobic porous membrane 3. Namely, since the org. material removing apparatus 2 using activated carbon, etc., is used in the pretreatment, the hydrophobicity of the hydrophobic porous membrane 3 is maintained and the operation is stabilized. Besides, since the waste water is treated with the hydrophobic porous membrane 3, the waste water can be purified by the two-stage operation, evaporation and membrane separation, and extremely pure water can be obtained with a compact apparatus. Consequently, the waste water such as shower water, night soil, soap water, plane cultivating waste water and breeding waste water is purified and the purified water can be used as drinking water, domestic water, cultivation water, etc. |
