Abstract

The biodegradation of Tetrabromobisphenol A (TBBPA) using anaerobic co-metabolism was carried out and the mechanism was also explored deeply. When influent TBBPA concentration was 75μg/L, the excellent performance was obtained with TOC and TBBPA removal efficiencies of 88.6% and 81.7% respectively. The half-life of TBBPA was calculated to be 21.97h at TBBPA concentration of 25μg/L. For further study, the intermediary metabolism substances were analyzed, and methyl-3, 4-dimethoxybenzoate was detected and considered as the important single benzene ring metabolite of TBBPA, which meant the TBBPA was biodegraded deeply. Simultaneously, the microbial diversity analysis demonstrated Azoarcus and Trichococcus species were responsible for the biodegradation of TBBPA in anaerobic co-metabolism system.

Key words： tetrabromobisphenol A anaerobic co-metabolism biodegradation
