Abstract
Through a long-term experiment, the performance of membrane bioreactor(MBR) for contaminants removal and membrane fouling was investigated. The results demonstrated that the removal effect of COD and NH3-N by the MBR was better. The effluent COD and NH3-N were lower than 50mg/L and 4mg/L, respectively. The observation by using the scanning electronic microscope(SEM) presented at the beginning of membrane filtration, there was no fouling in the membrane pores. With the continuous operation of the MBR, foulants shaped like mud cakes appeared in the membrane poles. The increasing of MLSS(mixed liquor suspended solids) concentration in the bioreactor didn’t increase membrane fouling. During the 75 days of operation, MBR cleaning was carried out twice.
