This review examines the potential of anaerobic membrane bioreactor (AnMBR) to serve as the core technology for simultaneous recovery of clean water, energy, and nutrient from wastewater. The potential is significant as AnMBR treatment can remove a board range of trace organic contaminants relevant to water reuse, convert organics in wastewater to biogas for subsequent energy production, and liberate nutrients to soluble forms (e.g. ammonia and phosphorus) for subsequent recovery for fertilizer production. Yet, there remain several significant challenges to the further development of AnMBR. These challenges evolve around the dilute nature of municipal wastewater, which entails the need for pre-concentrating wastewater prior to AnMBR, and hence, issues related to salinity build-up, accumulation of substances, membrane fouling, and membrane stability. Strategies to address these challenges are proposed and discussed. A road map for further research is also provided to guide future AnMBR development toward resource recovery.
本综述考察了厌氧膜生物反应器（AnMBR）作为同时从废水中回收清洁水、能源和营养物质的核心技术的潜力。由于 AnMBR 处理可以去除与水再利用相关的广泛的痕量有机污染物，将废水中的有机物转化为沼气以进行后续的能源生产，并将营养物质释放到可溶形式（例如氨和磷）以进行后续的肥料生产，因此这种潜力是巨大的。然而，AnMBR 的进一步发展仍然存在一些重大挑战。这些挑战围绕着城市废水的稀释性质展开，这需要在 AnMBR 之前对废水进行预浓缩，因此，与盐度积累、物质积累、膜污染和膜稳定性相关的问题。提出并讨论了应对这些挑战的策略。还提供了进一步研究的路线图，以指导未来的 AnMBR 发展实现资源回收。
