介绍了用中空纤维超滤器对大庆油田含油污水进行过滤净化的研究实验结果表明，开发的膜组件在通量上比常规的中空纤维组件大３～４倍，在０．０８ＭＰａ的压差下，其稳定通量达到最大，采用自配的清洗液清洗后，通量恢复达９５％以上 The hollow fiber ultrafilter was used to purify the oily wastewater in Daqing Oilfield. The experimental results show that the developed membrane module is 3 ~ 4 times larger than the conventional hollow fiber module in the flux, with the pressure difference of 0.08MPa , Its maximum stable flux, using self-cleaning liquid cleaning, flux recovery up to 95% 
