• 摘要：通过考察某油田含油废水中COD、石油类污染物、悬浮物、氨氮以及挥发酚等污染物的浓度变化，评估了UASB-SMBR组合工艺处理油田含油废水的可行性以及聚四氟乙烯膜的抗油污性能.实验结果表明该工艺对含油废水中COD、石油类污染物、悬浮物、氨氮以及挥发酚等各类污染物质的平均去除率均在96%以上，工艺出水水质满足国家污水综合排放标准.膜污染的加重使得膜透水率逐渐降低，但在化学清洗之后透水率恢复到95%以上.

• Abstract：A process combining UASB and SMBR was developed and operated for oily wastewater treatment from one oilfield. By monitoring the concentration variation of COD, petroleum pollutant, suspended solid, NH₃-N and volatile phenol, the study investigated the feasibility of the UASB-SMBR process for treating oily wastewater. Special attention was paid on observing the oil resistant performance of PTFE membrane. The results suggested that the average removal efficiencies of COD, petroleum pollutant, SS, NH₃-N and volatile phenol were all above 96%, indicating that the effluent achieved the national sewage discharge standard. Membrane permeability tended to drop off along with the increasing membrane fouling, but the permeability could be restored above 95% after chemical cleaning.
