摘　　要：通过中试系统的运行,研究了表面水力负荷q、温度及气水比等工程控制参数对曝气生物滤池处理城市污水效果的影响。结果表明,温度对微生物的代谢水平具有显著影响,适宜的温度应控制在不小于15℃水平;在20℃的条件下,即便在q高达3.0m3/(m2·h)时,其出水的SS,COD和NH4+-N浓度也可分别保持在15mg/L,60mg/L,18mg/L以下;在q为3.0m3/(m2·h),20℃的条件下,曝气生物滤池用于处理生活污水时,气水比控制为3是比较合理的。Based on the performance of a pilot-scale system treating municipal wastewater, the influences of surface loading rate, temperature and the ratio of air to water on a Biological Aerated Filter （BAF） are investigated in this paper. The results show that the temperature of wastewater should keep above 15℃. When the surface loading rate reaches as high as 3.0 m^3/（m^2·h） with the temperature of 20℃, the effluence concentration of SS, COD and NH4^＋-N could still keep below 15 mg/L, 60 mg/L and 18 mg/L, respectively. It is reasonable to adopt a ratio of air to water of 3.0 when the BAF is used to treat municipal wastewater.
