description The invention discloses an oil-gas field wastewater treatment system and a method utilizing forward osmosis technology. The system comprises a sedimentation tank, ultrafiltration equipment, a raw material liquid tank, forward osmosis membrane equipment, a driving liquid tank, electrodialysis equipment and a water storage tank. The wastewater treatment process disclosed in the invention can efficiently treat oil-gas field wastewater and is stable in operation, and the wastewater concentration rate is higher than 90%; rotary cross-flow membrane treatment equipment is adopted to relieve the concentration polarization phenomenon, membrane pollution is effectively controlled, and the service life is prolonged; the system is capable of realizing a self-circulation process which not only can efficiently treat oil-gas field wastewater, but also can recycle water resources. 本发明公开了一种利用正渗透技术的油气田废水处理系统及方法，该系统包括：沉淀池、超滤设备、原料液池、正渗透膜设备、驱动液池、电渗析设备及蓄水池。本发明的废水处理工艺能够高效处理油气田废水且运行稳定，废水浓缩率超过90％；旋转错流式膜处理设备使浓差极化现象得到缓解，膜污染得到了有效控制，提高了其
