摘　　要：采用截留相对分子质量为10×10^4的聚偏氟乙烯超滤膜组件，对大庆油田采出水电渗析脱盐进行预处理。实验结果表明，超滤适宜的膜面流速是3．0～3．5m／s，跨膜压差0.30～0.35MPa，工作温度35～40℃。超滤能降低浊度达95％，对油及悬浮物的去除率超过90％。超滤能满足电渗析预处理的要求。The ultrafiltration experiment of electrodialysis pretreatment for produced water desalination in Daqing Oilfield was worked by taking polyvinylidene fluoride（PVDF） with a cutioff relative molecular weight of 10 × 10^4 as ultrafiltration membrane. The results show that a feed flow velocity from 3.0 to 3.5 m/s, a transmembrane pressure from 0.30 to 0.35 MPa and a temperature from 35 to 40 ℃ are the best operating conditions. The turbidity of the produced water treated by ultrafiltration decreases 95 %, and removing oil and suspension substance is up to 90 %. The ultrafiltration technique can meet the requirements of eleetrodialysis pretreatment for produced water desalination.
