| 摘 要： | 研究了中试规模的上向流曝气生物滤池(UBAF)处理生活污水时,滤层高度与工作性能的相关性。结果表明:当水力负荷超过3.0m~3/(m~2·h)时,COD_(Cr)、NH_4~+-N的去除率均与滤层高度呈正相关;当水力负荷低于3.0m~3/(m~2·h)时,COD_(Cr)的去除率只与滤池下部滤层高度呈正相关,在滤池上部滤层处几乎保持不变,而NH_4~+-N的去除率则与滤池上部滤层高度呈正相关。在所有水力负荷工况下,SS的去除率均与滤层高度无相关性,且80％以上的SS被反应器最下部0.9m高的滤层所截获。

| Abstract: | The correlativity between performance and filter height has been studied in a pilot scale biological aerated filter for treating domestic sewage. The result show; for hydraulic loading higher than 3. 0 m3/(m2. h ) , the removal efficiency of CODCr, NH4+ -N have positive correlation with the height of filter, when hydraulic loading was below 3.0m/(m2. h) , the removal efficiency of CODCr only have positive correlation with height of lower section in filter and have almost no change in upper section of filter, however, the removal efficiency of NH4+ -N have positive correlation with height of upper section in filter. Under all hydraulic loading operated during the experiment, removal efficiency of SS have no correlation with height of filter, and up to 80% of SS was captured in the first 0. 9 m. |
