摘要： 在进水流量16.5 L/h，回流比200%，滤速2.8 m/h的工况下，考察了前置反硝化BAF工艺的处理效果。结果表明：在缺氧段与好氧段滤料体积比为1：1、1：2、1：3条件下，出水COD、NH3-N和TN均能达到《城镇污水处理厂污染物排放标准》（GB 18918—2002）的一级标准；在滤料体积比为1：4条件下，出水COD超出排放标准，而NH3-N和TN的出水效果仍满足一级排放标准。

Abstract: When the influent flow is 16.5 L/h, reflux ratio 200% and filtering velocity 2.8 m/h, the treatment effect of pre-denitrification BAF process has been investigated. The results manifest that when the filter volume ratios of anoxic section and aerobic section are 1:1, 1:2, and 1:3, its effluent COD, NH3-N and TN are able to reach the pri-mary Urban Sewage Treatment Plant Pollutant Discharge Standards(GB 18918—2002). When the filter volume ratio is 1:4, its effluent COD exceeds the discharge standard, but the effluent of NH3-N and TN still meets the requirements of priamry discharge standard.
