Abstract
In this study, the anaerobic baffled reactor contained sediment microbial fuel cell (MFC) was combined with anaerobic/aerobic membrane bioreactor (AnMBR/MBR). The brewery wastewater treatment and membrane fouling mitigation strategies were studied comprehensively. During anaerobic treatment process in this study, the chemical oxygen demand (COD) removal ratio of brewery wastewater could be maintained at 73.87% when the hydraulic retention time (HRT) was reduced from 42.44h to 22.60h. For membrane fouling mitigation in AnMBR, regular aeration was more effective than back flush, and the fouling could be inhibited further when both controlling ways were adopted at the same time. For membrane fouling mitigation in AnMBR of this study, only 0.52%–0.99% of electric energy was required for fouling mitigation, but 31.80% of energy was needed in MBR.
