摘　　要：随着聚合物驱在三次采油中大量应用,采出废水黏度大,使现有的海上平台废水处理运行产生了一定的困难。采用电-Fenton技术处理聚合物驱采油废水,室内研究发现处理每升水的最佳条件为:电流强度为3.0 A,极板间距为4.0 cm,反应时间为15 min,pH值调节至4.0,质量分数为30%的双氧水的投加量为1.0 mL,聚合物去除率可达99.21%。电-Fenton技术用于降黏兼有电絮凝、气浮、沉降、高级氧化的作用,对现场含聚含油废水处理具有积极的指导意义。With the wild application of polymer flooding technology in tertiary oil recovery, the viscosity of produced water becomes higher, which makes the treatment of wastewater from offshore platform more difl＇ieult. Eleetrie-Fenton technology was used to treat polymer flooding oil-extraction wastewater. The results of indoor experiment indicated that, for the treatment of a liter of water, the removal rate of polymer could reach 99.21% under the optimal condition as follows： the current intensity was 3.0 A, the space between two electrode plates was 4.0 em, the reaction time was 15 min, the pH value was 4.0, the dosage of hydrogen peroxide with mass fraction of 30% was 1.0 mL. Electric-Fenton technology plays the role of viscosity reducing, as well as electric floeeulation, air floatation, sedimentation and advanced oxidation at the same time, therefore, it has an active guiding meaning for the treatment of wastewater containing polymer and oil.
