| 摘 要： | 为实现污水的无能耗处理,根据"跌水曝气式生物滤塔"专利设计制作了5层跌水曝气生物滤池,对其在生活污水处理过程中的自然挂膜过程进行研究,分析了挂膜过程中生物相的变化及对COD、NH4+-N的去除效果。试验结果表明:COD的去除主要集中在滤池的中上部(第1、2、3滤料层),而对NH4+-N的去除主要集中在中下部(第4、5滤料层)。当COD的去除率稳定在61.5%左右,NH4+-N的去除率稳定在56%以上,且滤料中的生物相趋于稳定时,标志着反应器挂膜已完成,历时约21 d。

| Abstract: | To realize non-energy consumption domestic sewage treatment,the biological falling water aerated filter was developed and a biofilm formation experiment was conducted.The alternations of biofacies and the treatment efficiency of COD and NH+4-N were analyzed.The results show that COD is mainly removed on the top and middle layers of the biological falling water aerated filter,and the removal of NH+4-N is mainly at the bottom of it.When the removal rate of COD is steady at 61.5%,the removal rate of NH+4-N is also steady at 56%,and the biofacies are steady,the biofilm is formed.The whole process lasts about 21d. |
