针对聚合物驱油废水高黏度、强乳化稳定性导致油水分离困难的问题，构建了介质阻挡放电（DBD）结构的非平衡态等离子体反应器，开展了模拟含聚废水油水分离实验。系统考察了溶液浓度、油水体积比、放电电压、放电时间及电极配置等因素对油去除行为的影响，并结合溶液黏度及水质参数变化分析分离机理。结果表明，在HPAM 质量浓度 1 g/L、油水体积比 1:100、放电电压峰值 30 kV、单电极配置、处理时间 12 min 条件下，油去除率可稳定达到 99%以上。处理过程中溶液黏度由 180.7 mPa·s 降至 58 mPa·s，且与油去除率呈负相关。机理分析认为，非平衡态等离子体通过氧化作用与离子环境调控的协同机制实现对含聚废水体系结构的调控，降低体系黏度，从而实现高效油水分离。
Abstract：Aiming at the difficulty of oil-water separation caused by high viscosity and strong emulsion stability of polymer-containing wastewater， a non-equilibrium plasma reactor with dielectric barrier discharge (DBD) configuration was constructed， and oil-water separation experiments were carried out on simulated polymer-containing wastewater. The effects of solution concentration， oil–water volume ratio， discharge voltage， treatment time， and electrode configuration on oil removal behavior were systematically investigated， and the separation mechanism was analyzed in combination with changes in solution viscosity and water quality parameters. The results show that under the conditions of an HPAM concentration of 1 g/L， an oil–water volume ratio of 1:100， a peak discharge voltage of 30 kV， a single-electrode configuration， and a treatment time of 12 min， the oil removal efficiency can stably exceed 99%. During plasma treatment， the solution viscosity decreases from 180.7 mPa·s to 58 mPa·s and exhibits a strong correlation with oil removal efficiency. Mechanistic analysis indicates that non-equilibrium plasma regulates the structural characteristics of polymer-containing wastewater through the synergistic effects of oxidative reactions and ionic environment modulation， resulting in viscosity reduction and consequently achieving efficient oil–water separation.
