Experimental Study on the Treatment of Petroleum Produced Water Using Three-dimensional Electrode-electro-Fenton Coupling Method

本研究采用自制三维电极-电芬顿反应器,处理模拟的石油采出水。在保证出水水质的情况下,曝气量为0.8 L/min, pH值为3.5,电解电压为12 V,电解质投加浓度为5 g/L,极板间距为5 cm,系统耗电量较低,COD去除率达到85.9%,油脂去除率达到93.29%。三维电极-电芬顿耦合法对石油采出水处理效果好,无二次污染,运行简单,可在实际工程中得到推广应用。

This study used a self-made three-dimensional electrode-electro-fenton reactor to treat simulated petroleum produced water.While ensuring water quality,the aeration rate was 0.8 L/min,the pH was 3.5,the electrolysis voltage was 12 V,the electrolyte concentration was 5 g/L,and the electrode spacing was 5 cm.The system showed low power consumption,achieving COD removal rate of 85.9%and grease removal rate of 93.29%.The three-dimensional electrode-electro-fenton coupling method has good treatment effect on petroleum produced water,with no secondary pollution,simple operation,and potential for widespread application in practical engineering.
