摘　　要：以某炼油厂的污水场二沉池外排污水为水源,经预处理+超滤+反渗透工艺处理后产水回用于脱盐水站补水。其中预处理包括高效纤维过滤、生物活性炭和电絮凝。试验结果表明,高效纤维过滤+生物活性炭+电絮凝+超滤+反渗透工艺可行,炼油废水经过该工艺处理后,出水中油≤1 mg/L、CODMn≤1 mg/L、氨氮≤1 mg/L,达到了该厂对离子交换树脂进水要求。The effluent water from secondary settling tank in the wastewater treatment plant of a refinery, as the wa- ter source, has been treated by the combined process of pretreatment-ultrafiltration-reverse osmosis. The water pro- duced by this combined process can be reused as make-up water for the desalted water plant. The said pretreatment process includes the processes of efficient fiber filter, biological activated carbon and electrocoagulation. The experi- mental results show that the combined process of efficient fiber filter-biological activated carbon-electrocoagula- tion-ultrafihration-reverse osmosis is feasible and effective. After the refinery wastewater is treated by this process, the oil, COD_Mn,and NH3-N contained in the effluent would be less than 1 mg/L, 1 mg/L,and 1 mg/L,respectively, meeting the requirements for ion exchange resin influent water in the refinery.
