摘　　要：由于炼油污水厂恶臭气体中挥发性有机气体浓度波动大,造成生物滴滤塔不能稳定运行,本试验采用生物洗涤法对炼油污水厂恶臭气体进行预处理研究.试验结果表明:生物洗涤液中混合液悬浮固体浓度达到8mg/L,环糊精添加量20mg/L,对挥发性有机气体脱除率达到60%以上,满足生物滴滤塔设计的进气要求,出口气达到《恶臭污染物排放标准》(GB14554-93)二级厂界标准规定.The fluctuation of the content of organic odorous gases from refinery sewage plants leads to the instability of biotrickling filter. Biological washing is adopted in the pretreatment of the odorous gases. It is shown through the results that the MISS （ mixed liquor suspended solids） of biological washing liquid concentrations reaches 8 mg/L, the surfactant 20 mg/L and the removal rate of volatile organic gases 60%, which meet the biotrickling filter design requirements. The export malodorous gases can reach secondary factory bound standard according to the stench of standards for pollutants discharge （ GB14554 - 93）.
