补充资料：航天员供水和水处理系统
收集、净化废水并根据航天员的需要供应饮用水和生活用水的设备。人体除呼吸、出汗和皮肤蒸发排出水分外，每人每天排尿量为1000～1600毫升,耗水量约2.5公斤以上。为保证人体的代谢需要，失去的水分必须从食物和饮水中得到补充。如果再加上洗漱用水，每人每天消耗的水量还更大一些。这些饮水和用水完全靠航天器自身携带是无法承受的负担。短期飞行的载人航天器采用贮水容器，从地面携带清洁水。采用燃料电池作为一次能源的航天器主要依靠燃料电池产生的水，并收集和贮存来自湿度控制系统的冷凝水，用离子交换膜、活性炭或化学吸附剂加以净化和消毒后，作为饮用、洗漱和水蒸发器的水源。长期飞行和多乘员的航天器必须装备复杂的废水处理系统，将尿和洗漱水等废水回收、处理，使废水再生。
