摘　　要：In this study,the enhanced mineralization of p-fluoronitrobenzene(p-FNB)was achieved in a methane-based hollow-fiber membrane biofilm reactor(CH4-MBfR).A TOC removal of 73.2%was gained in CH4-MBfR with an influent p-FNB loading of 42―84 mg/L·d,while only 40.6%of TOC was removed in the corresponding control biological reactor(BR).Moreover,the reaction rate constant for TOC removal in CH4-MBfR was 2.48 times that of the BR.VFAs was only detected in CH4-MBfR,although oxidation elimination was the first step for p-FNB removal in both systems.Methylococcus and Methylononas were dominant strains in the CH4-MBfR,which may play an important role in converting CH4 to VFAs and then further enhancing the mineralization efficiency of p-FNB.
