| 摘 要： | 交替曝气时间是影响新型两级生物滤池工艺除磷效果的关键因素。在四种不同的厌氧／好氧交替曝气时间下，考察了该工艺对TP的去除效果。试验结果表明：交替曝气时间为12h时除磷效果最好，对TP的平均去除率为80．18％，平均出水TP为0．94mg／L，达到了《城镇污水处理厂污染物排放标准》（GB18918-2002）的一级B标准；厌氧释磷的最佳反应时间是9h，好氧吸磷的最佳反应时间是6h，除磷率最高可达87．65％。

| Abstract: | The length of alternate aeration influences phosphorus removal in the alternately aerated two-stage biofilter.Thus,the phosphorus removal efficiency at four anaerobic/aerobic alternate aeration times was investigated.The results indicate that when the alternate aeration time is 12 h,the phosphorus removal efficiency is at its peak.The TP removal rate averages 80.18% and the effluent TP concentration is 0.94 mg/L,satisfying the first level B criteria specified in the Discharge Standard of Pollutants for Muni... |
