| 摘 要： | 通过两级曝气生物滤池处理城市生活污水的中试研究，探讨气水比、水力负荷、回流比及甲醇投加量等工程控制参数对两级曝气生物滤池处理城市生活污水效果的影响，结果表明，当气水比为3：1，水力负荷为2～3m3／（m2·h），回流比为80％，甲醇投加量为80mg／L时，两级曝气生物滤池处理效果最佳，其出水可达《城镇污水处理厂污染物排放标准》中的一级A标准。

| Abstract: | A research was conducted to obtain the engineering control parameters, such as air/water ratio, hydraulic loading, reflux ratio, methanol dosage, etc, by municipal wastewater treatment with two-stage biological aerated filter in pilot-scale. It was aimed at investigating the effectiveness of the two-stage BAF in treating municipal wastewater. The results of the research showed that the two-stage BAF was most effective under these conditions： air/water ratio of 3 ： 1 ; hydraulic loading of 2 ~-3 m3/（m2·h）; reflux ratio of 80 % and methanol dosage of 80 mg/L. The treated water could reach the A-level of the discharge standard of pollutants for municipal wastewater treatment plants. |
