| 摘要: |
| 空间站中水资源的补充对实现宇航员长期在轨驻留至关重要。将航天员的尿液处理后循环回用是供水的必要途径之一,其占据了回收水量的绝大部分。然而,传统尿液处理方法存在设备庞大、流程复杂和原子利用率低等问题。因此设计了新型污水处理及回用系统:基于尿素电氧化技术处理尿液,引入甲烷燃料电池与Sabatier反应器和氢氧燃料电池联用,以进一步利用尿液处理产物,通过设计分级处理及动态调控系统,精准配置空间站内水资源。该设计系统有助于节省宝贵空间并降低处理能耗,有望提高水的回收率同时实现资源的优化配置,为空间站内水资源的循环利用提供新思路。 |

| Abstract: |
| The replenishment of water resources in a space station is essential for achieving an astronaut's long-term and on-orbit residence. Recycling his or her urine is one of important and major ways of wastewater recovery. However, traditional urine treatment methods have the disadvantages of equipment that takes large space, complex procedures and low atomic utilization. Therefore, this paper designs a novel wastewater reuse system that treats urine based on urea electrooxidation technology, introduces methane fuel cell coupled with the Sabatier reactor and hydrogen-oxygen fuel cell to further utilize urine treatment products and to allocate water resources precisely in the space station through designing grading treatment and dynamic control systems. The wastewater reuse system designed in the paper contributes to saving valuable space and reducing energy consumption during urine treatment, thus improving water recovery rate and optimizing resource allocation. |
