摘　　要：因气水同向流,在升流式曝气生物滤池(UBAF)运行中,滤料表面脱落的生物膜易随出水流出,影响出水水质。利用后置石英砂滤池的截滤能力,可有效截留UBAF出水中夹带的细小悬浮物和微型生物,提升出水水质。试验表明,后置石英砂滤池可使UBAF工艺对污水中COD、NH3-N、SS、色度等污染指标的去除率均有提高。Beacuse of the same direction of water and gas,biological membrane shed from the surface of filtration material will flow out easily when the up flow biological aerated filter （UBAF） is running. Then the quality of water can be affected. After addding a quartz sand filter, small suspended solids can be effectively hold back.Experiments show that the post of quartz sand filter can make the UBAF impove the removal rates of COD, ammonia nitrogen wastewater, SS,chrominance and turbidity.
