摘　　要：在传统活性污泥A/O工艺中投加固定填料,形成悬浮生长和附着生长两种生物结构,用于生活污水处理试验研究.结果表明,在HRT=6.4～7.2,h,气水比为12∶1～15∶1的条件下,CODcr、SS、NH3-N、TN的去除率分别为82%、97%、95%、80%,且出水色度较低,取得稳定运行效果,为污水厂升级改造提供可行实验依据.Sewage treatment by casting fixed carriers in the traditional active sludge A/O process to form two kind of biological structures which are susppended growth and attachment growth is reaserched. The experimental results show that the process has high removal efficiences of CODer ,SS, NH3-N,TN as 95%,97%, 82%, 80% respectively under the condition of HRT =6.4-7.2 h,and the ratio of gans to water of 12 ： 1～15 ： 1. The Chromaticity is very low and＇ it also achives the stable running effects during water leakage. The process provides us feasible experimental data for sewage farm reconstruction.
