Abstract:

The hollow fiber membrane bioreactor（MBR） has been used for treating crude refinery wastewater andits performance has also been studied. The results show that the MBR process is highly efficient in treatingrefinery wastewater. The removal rates of COD， NH3-N and oil are 91.5%， 96.7% and 84.7% respectively. TheMBR effluent water COD is 64 mg/L， NH3-N 1.85 mg/L and oil content is less than 3.0 mg/L. The effluent waterquality meets the requirements of the First Grade Standard of Wastewater Discharge.

Key words: refinery wastewater, membrane bioreactor, pilot study
