摘　　要：利用自主筛选驯化的菌株,自制模拟屋面绿化工程的生物填料塔反应器,以屋面绿化工程中的营养土、绿色植物为天然生物材料,通过营养土和植物组成的生物过滤系统对油烟废气进行生物处理研究。考察了反应温度、气体停留时间、入口浓度、进气流量和营养液循环量等对油烟废气去除效果的影响。结果表明,当反应温度为33℃左右、停留时间为30 s、入口油烟废气小于3.0 mg/L、进气流量为0.8 L/h、营养液循环量为5 L/h时,对油烟废气有很好的去除效果,去除率可达到90%以上。Green roof engineering based biofiliter was established for biodegradation of oil fume.The bacteria applied in biofilter was isolated from oil fume contaminated soil and cultured with rape oil as the sole carbon source.The batch removal of oil fume by the biofiliter was investigated to determine the effect of temperature,residence time,inlet concentration,gas flow rate and the nutrient solution circulation rate on oil fume removal efficiency.Results showed that temperature was the key factor that affecting the biofiliter performance,and the optimum temperature was 33 ℃.Under the retention time of 30 s,inlet oil fume concentration of below 3.0 mg/L and gas-flow rate of lower than 0.8 L/h,nutrient sprinkling was 5 L/h,biodegradation efficiency of oil fume could achieved more than 90%.
