Renewable energy, water conservation, and environmental protection are the most important challenges today. Osmotic membrane bioreactor (OMBR) is an innovative process showing superior performance in bioenergy production, eliminating contaminants, and low fouling tendency. However, salinity build-up is the main drawback of this process. Identifying the microbial community can improve the process in bioenergy production and contaminant treatment. This review aims to study the recent progress and challenges of OMBRs in contaminant removal, microbial communities and bioenergy production. OMBRs are widely reported to remove over 80% of total organic carbon, PO, NH and emerging contaminants from wastewater. The most important microbial phyla for both hydrogen and methane production in OMBR are Firmicutes, Proteobacteria and Bacteroidetes. Firmicutes' dominance in anaerobic processes is considerably increased from usually 20% at the beginning to 80% under stable condition. Overall, OMBR process has great potential to be applied for simultaneous bioenergy production and wastewater treatment.
可再生能源、水的节约和环境保护是当今最重要的挑战。渗透膜生物反应器（OMBR）是一种创新的工艺，在生物能源生产、消除污染物和低污染倾向方面表现出优异的性能。然而，盐度积聚是该工艺的主要缺点。鉴定微生物群落可以提高生物能源生产和污染物处理过程中的效率。本综述旨在研究 OMBR 在污染物去除、微生物群落和生物能源生产方面的最新进展和挑战。有报道称，OMBR 广泛用于从废水中去除超过 80%的总有机碳、PO、NH 和新兴污染物。对于 OMBR 中氢气和甲烷的生产，最重要的微生物门是厚壁菌门、变形菌门和拟杆菌门。在稳定条件下，厌氧过程中厚壁菌门的优势从通常的 20%大幅增加到 80%。总的来说，OMBR 工艺具有很大的潜力，可用于同时进行生物能源生产和废水处理。
