An amplification work is carried out in accordance with the pre-modified PTFE membrane fine filtration technology for treating oil-bearing water in oilfields, to verify its feasibility, and at the same time, to determine the design and operation parameters. The results show that after the oil-bearing water is treated by the modified PTFE fine filtration equipment,which is used as a second grade equipment for treating oil-bearing wastewater,the quality can reach the water quality control index of low permeability oil-layer reinjection in Daqing Oil-field ,carrying out the application of membrane technology to the oil-beating wastewater treatment. The treated water quality not only has been improved, but also ensured the wastewater treatment station to provide an effective measure.%根据改性聚四氟乙烯膜精细过滤技术处理油田含油污水的前期试验,进行工业性放大试验,验证了其处理含油污水的可行性,确定了过滤器的设计和运行参数.结果表明,作为油田含油污水处理工艺中的二级过滤设备,改性聚四氟乙烯膜精细过滤器处理后的水质能够达到大庆油田低渗透率油层回注水水质控制指标,实现了膜滤技术在油田含油污水处理上的应用,提高了处理后的水质,也为污水处理站出水水质达标提供一种有效技术措施.
