Title: Influence of hydraulic retention time on efficiencies of high concentration PAC-MF bioreactor treating slightly polluted surface water
Abstract: In this study,the influence of hydraulic retention time on feasibility,efficiency and membrane fouling of slightly polluted surface water treatment by a high concentration PAC-MF bioreactor were investigated. During three months operation,TOC,NH4 + -N,nitrobenzene,and TMP were measured to evaluate the MBR performance. The results show that,when HRT reduces from 3 h to 1 h,removal efficiency of TOC and ammonia-nitrite decrease a little. However,there is little effect of HRT on nitrobenzene. And the optimal hydraulic retention time is 1 h.
