摘　　要：采用"高效絮凝+纳滤"联用工艺技术处理某大型油田的压裂废水,经过高效絮凝预处理之后,纳滤工艺表现出高膜通量、高浓缩倍数、高膜通量恢复率等优点,且对压裂废水中COD、水的硬度、二价及多价阳离子、硫酸根离子(SO_4^(2-))的去除率分别高达80%,93%,90%,100%,"高效絮凝+纳滤"联用工艺技术为高效再生利用压裂废水提供了新的解决方案。In this paper, using coupling technique of ＂efficient flocculation＋nanofiltration＂ to treat fracturing waste water of a large-scale oilfield, the nanofiltration process shows advantages of high membrane flux, high concentration multiple and high recovery rate of high membrane flux through pretreatment of efficient flocculation. And, removal rate to COD, water rigidity,divalent or multivalence kation and sulfate ion（SO4^（2-）） in fracturing waste water respectively reach 80%, 93%, 90% and 100%.Coupling technique of ＂efficient flocculation＋nanofiltration＂ provides new solutions for high efficient and recycling fracturing waste water.
