| Abstract: | The pretreatment process of Coagulation and sedimentation and the biochemical treatment process of Hydrolysis acidification and Membrane Bio-Reactor process was adopted to treat the wastewater of crude oil dehydration and sludge dewatering filter solution with bad biodegradability and high salinity.The operation results showed that when the inflow index of conductivity is 6500~8000 μs/cm、COD 7824~18334 mg/L and oil content 390~579 mg/L,the average removal efficiency for COD is 99.7 % and oil content is 98.4 %.The effluent quality reaches the first level criteria specified in Integrated Wastewater Discharge Standard（GB8978-1996）. |
