The water regeneration system for future space stations was proposed and developed in this project. The system to filtrate waste water was composed of three main components, immobilized urease, charged membrane and ion-exchanger. Urea, which is one of primary product in waste water, is decomposed to ammonium ion, then separated from other coexsting cations by positively charged membranes and removed by ion-exchanger. The cationic membranes were made by attachment of tertiary or quaternary amine to different types of commercially available polyethylene membrane. The experiments showed that glycizylmethacrylate grafted membrane could have selective permeability between cations and non-ionic substances and could be used for this water regeneration system.The feasibility of he system was investigated using the developed membrane and test solution of which composition was similar to urine. The results indicated that the principle of this method was promising to remove urea selectively from the solution, thus to establish a water regeneration system for future use in space stations.

本项目提出并开发了未来空间站的水再生系统。该废水过滤系统主要由固定化脲酶、带电膜和离子交换器三部分组成。尿素是废水处理的主要产物之一，它通过带正电的膜分解成铵离子，与其他共存的阳离子分离，再通过离子交换器去除。阳离子膜是由叔胺或季胺附着在不同类型的市售聚乙烯膜上制成的。实验表明，甲基丙烯酸甘酰基接枝膜在阳离子和非离子物质之间具有选择性通透性，可用于该水再生系统。利用研制的膜和组成与尿液相似的测试溶液，对该系统的可行性进行了研究。结果表明，该方法的原理有望从溶液中选择性地去除尿素，从而建立一个将来用于空间站的水再生系统。
