Effect of temperature on treating chemical synthesis-based pharmaceutical wastewater containing 7-ACA by a novel multi-stage loop membrane bioreactor

摘要

BACKGROUND7-amino cephalosporanic acid (7-ACA) is the most critical intermediate for cephalosporin antibiotics but has caused serious water pollution. In this study, a bench-scale test was conducted with a novel multi-stage loop membrane bioreactor (MsLMBR) to treat chemical synthesis-based pharmaceutical wastewater containing 7-ACA.
