采用粉煤灰复合滤料曝气生物滤池(BAF)装置处理污水,研究了气水体积比、水力负荷、进水污染物负荷对COD和NH3-N去除效果的影响.结果表明,在进水COD和NH3-N的质量浓度分别为200mg/L和25 mg/L时,适宜的气水体积比为10∶1,COD和NH3-N的去除率能够分别达到77.93％和84.78％；适宜的水力负荷为1.01 m3/(m2·h),COD和NH3-N的去除率能够分别达到87.88％和90.01％.反应器具有较强的抗污染物冲击负荷的能力,有机负荷在1.03～3.68kg/(m3·d)时,COD去除率均保持在75％以上；当氨氮负荷在0.22～0.44 kg/(m3·d)化时,NH3-N去除率均保持在85％以上.
