目的 针对废水生物处理技术应用于空间条件下的瓶颈问题，构建空间废水生物处理试验系统并考察试验系统生化性能，为空间废水生物处理提供技术支撑。方法 构建基于膜曝气生物膜反应器（MABR）工艺的空间废水生物处理试验系统，并通过77 d连续流试验，研究聚偏氟乙烯（PVDF）和聚丙烯（PP）膜组件处理模拟空气冷凝水的生化性能。结果 两个膜组件平均总有机碳（TOC）去除率均能维持在90%以上，具备良好的有机物去除能力；空气源供氧模式下氨氧化能力较低，而在氧气源无泡供氧模式下，能同步获得90%以上的氨氧化率和总氮去除率，表现出良好的同步硝化和反硝化性能；PP膜组件中氮素转化功能菌群丰度高于PVDF膜组件，具备更优的氮素转化性能。结论 废水生物处理试验系统能较好地适应空气冷凝水的处理，为空间废水处理提供了新的技术途径。
