摘　　要：针对某炼油厂焦化含油废水的特点,开展了三维电极处理含油废水的试验研究,对处理时间、电压、活性炭填充量、极板间距及曝气量等工艺参数进行考察优化,再通过处理前后水样的宏观和微观形貌的对比分析以及GC-MS联用分析等,进一步评价三维电极对废水的净化处理效果。试验结果表明:三维电极处理焦化含油废水的优化工艺条件为处理时间180 min、电解电压30 V、活性炭填充量500 g、极板间距6 cm、曝气量1 L/min,此时除油率可达到96.73%。三维电极对焦化含油废水有较好的处理效果,基本实现了焦化含油废水的净化处理。In view of the characteristics of coking oily wastewater in a refinery plant, an experimental research on oily wastewater treatment by three-dimensional electrode method was carried out, the technological parameters such as treatment time, voltage, activated carbon filling quantity, plate spacing, aeration quantity and so on were investigated and optimized, and then, the purification effect of the wastewater by three-dimensional electrode method was further evaluated through the comparative analysis between the macroscopic and microscopic morphology of water samples before and after the treatment. The results of the experiment showed that, the optimal process condition for three-dimensional electrode method treating oily wastewater was as follows:the treatment time was 180 min, the decomposition voltage was 30 V, the activated carbon filling quantity was500 g, the plate spacing was 6 cm, the aeration quantity was 1 L/min, at the moment, the oil removal rate of the wastewater could reached 96.73%. It could be seen that, using three-dimensional electrode method to treat coking oily wastewater could obtain good effect and basically realized coking oily wastewater purification.
