Urine and other liquid excretions should be treated by the urine treatment system and reused. The pretreated urine is spin distilled using vapor compression distillation technology, and the collected water vapor is condensed to form distilled water. outlet to the water treatment subsystem for deep purification, thereby extracting and utilizing the water contained in urine. The recycled water purified by the water treatment subsystem exceeds the requirements of relevant national standards and can meet the requirements for long-term residence on the space station. . It is used for astronaut cleaning, oxygen production and other purposes.
How does the Chinese Space Station manage astronaut waste?
Astronauts live in space. They must consume a certain amount of materials. every day, manger The port also produces a lot of waste and excrement. There are no sewers in the space, so you can't dispose of waste. You can only seal them in special containers and store them regularly in the cargo spaceship.
Astronauts cannot wash dirty clothes in a washing machine and dry them before wearing them in space. Water resources are limited in the space station and the cost of washing clothes is too high, so they pack up and throw away their clothes. underwear after wearing it for a few days.
Once the mission is completed, the cargo spacecraft will sail toward Earth's atmosphere. Once in the atmosphere, friction between the air and the capsule causes it to heat up, explode and disintegrate, eliminating solid waste.
