Progress of Anaerobic Membrane Bioreactor in Municipal Wastewater Treatment

Anaerobic Membrane Bioreactor (AnMBR), as a new technology to achieve efficient energy recovery from municipal wastewater, has received widespread attention, but it still faces huge technical and economic challenges. The technical characteristics of AnMBR for municipal sewage treatment and the long-term control method of membrane fouling need further research, and the efficient operation at low temperature needs to be further solved. This review aims to discuss the research progress and bottleneck of AnMBR for municipal wastewater treatment through process characteristics, membrane fouling formation mechanism, low temperature regulation method and action mechanism. This paper discusses the main challenges and solutions in the process application process, and on this basis, looks forward to the development direction of AnMBR in municipal wastewater treatment. It aims to provide a reference for promoting AnMBR to treat low-concentration municipal sewage and realize the reuse of resources and energy in sewage.
