摘　　要：针对某炼油污水深度处理进行了中试研究,分析了臭氧、生物活性炭(BAC)的作用。研究结果表明,二级生化后污水中仍含有较高浓度的难降解有机物,是后续除盐装置运行不利的主要原因,该类物质难以被陶粒滤料曝气生物滤池有效去除,但可被BAC滤池有效降解。对于有机物的去除,生物活性炭的作用占主导地位,是否投加臭氧影响较小。臭氧对以生物絮体为主的悬浮物质有明显的氧化分解作用,实际应用时应采取必要的预处理措施,减少臭氧的额外消耗。Polit-scale study on the advanced treatment of refinery wastewater has been carried out. The functions of ozone and biological activated carbon are analyzed. The results show that the wastewater after the secondary biochemical treatment still contains refractory organisms with high concentration ,which is the main unfavorable reason for the subsequent demineralizing equipment operation. It is difficult for such organisms to be removed by ceramisite filter material biological aerated filter,but can be degraded efficiently by biological activated carbon filter. For the removal of organisms, biological activated carbon plays a major role. Whether ozone is added or not has less influence. Ozone has significant oxygenolysis effect on the suspended matter that mainly consists of biological flocs. Necessary pretreatment measures should be taken in actual applications,so as to reduce extra ozone consumption.
