Research advances on wastewater treatment performance of anaerobic membrane bioreactor enhanced by biochar

Abstract

Anaerobic membrane bioreactor(AnMBR) has received widespread attention from researchers because of its efficient degradation of organic matter and energy recovery ability in various wastewater treatment. Biochar has excellent adsorption and conductivity capabilities, and its addition to AnMBR for anaerobic digestion of wastewater can improve reactor performance and promote energy recovery. Based on this, a systematic review was conducted on the preparation and modification methods of biochar and their impact on the performance of biochar, as well as the research progress in using biochar to enhance the treatment performance of AnMBR in recent years. The role and main mechanisms of biochar in AnMBR were mainly discussed, and the existing problems and future development directions of biochar enhanced AnMBR research were pointed out, in order to provide theoretical basis and technical reference for the treatment of wastewater in AnMBR enhenced by biochar.
