稳定而大量产生的城市污水越来越被视为生产清洁水、生物能源和营养物质的宝贵资源。由于技术限制，传统的好氧和厌氧生物技术对MWW的高效生物能源和生物资源回收具有挑战性。新兴的厌氧膜生物反应器（AnMBRs）通过整合厌氧消化和膜过滤的优点，显示出克服这些限制的巨大潜力。本文简要介绍了anmbr的毫米波质量和工艺性能的基本方面。从工艺特性和能源效率方面评估了anmbr在提高性能、减轻污染和减少能源需求方面的最新发展。有前景的AnMBR配置包括沼气喷射式AnMBR、颗粒流化AnMBR、颗粒污泥式AnMBR、厌氧动态膜生物反应器（AnDMBR）和厌氧正向渗透膜生物反应器（AnFOMBR），并系统讨论了能量平衡，并基于生命周期评估（LCA）研究简要分析了经济效益和环境效益。最后，提出了一个技术框架，强调了AnMBR研究与开发的未来前景，重点是预处理和后处理方案、溶解甲烷管理和工艺优化，有望以经济上可行和环境可持续的方式推进AnMBR的大规模应用。
Municipal wastewater (MWW) produced in a stable and huge amount is increasingly regarded as a valuable resource for generating clean water, bioenergy and nutrients. Efficient bioenergy and bioresource recovery from the MWW are challenging in conventional aerobic and anaerobic biotechnologies due to technical limitations. The emerging anaerobic membrane bioreactors (AnMBRs) show great potential to overcome such limitations by integrating the merits of anaerobic digestion and membrane filtration. In this review, the fundamental aspects regarding MWW quality and process properties of AnMBRs are briefly introduced. Recent developments in AnMBRs towards performance enhancement, fouling mitigation and energy demand reduction are assessed in terms of process characteristics and energy efficiency. The promising AnMBR configurations targeted include biogas-sparging AnMBR, particle-fluidized AnMBR, granular-sludge AnMBR, anaerobic dynamic membrane bioreactor (AnDMBR) and anaerobic forward osmosis membrane bioreactor (AnFOMBR), with the energy balance systematically discussed as well as economic and environmental benefits briefly analyzed based on life cycle assessment (LCA) studies. Lastly, future perspectives for AnMBR research and development (R&D) are highlighted by a proposed technical framework with an emphasis on the pre-treatment and post-treatment options, dissolved methane management and process optimization, which are expected to advance large-scale AnMBR applications in an economically viable and environmentally sustainable manner.
