| 摘 要： | 为了实现污水的就地处理与回用，开发了接触氧化／BAF工艺，并对该工艺的挂膜启动进行了研究，分析了其挂膜过程中生物相的变化情况及对COD、NH4^＋-N的去除效果。结果表明，该工艺对COD的去除主要集中在接触氧化段，对NH4^＋-N的去除主要集中在BAF段；当接触氧化段对COD的去除率稳定在80％左右、BAF段对NH4^＋-N的去除率稳定在90％以上，且填料中的生物相趋于稳定时，标志着系统挂膜成功，历时约27d。此时，系统出水COD和NH4^＋-N的浓度分别稳定在50、0．2mg／L左右。

| Abstract: | To realize on-site treatment and reuse of urban domestic sewage,the contact oxidation/BAF process was developed and a biofilm formation experiment was conducted. The changes of biofacies and the treatment efficiencies of COD and NH+4-N were analyzed. The results show that the removal of COD is mainly achieved in the contact oxidation stage,and the removal of NH+4-N is mainly achieved in the BAF stage. When the removal rate of COD in the contact oxidation stage steadies at 80%,the removal rate of NH+4-N in t... |
