Abstract

Nutrient removal was investigated in a packed bed column, which was operated by changing of aerated and non-aerated periods. Good removal efficiencies for nitrogen and phosphorus were obtained at long aeration period. Highest nitrification efficiency was observed in run3 because the aeration period was enough to allow nitrification. NO3 concentration was not significantly changed during the cycle, because of simultaneous denitrification during aerobic stage. Nitrogen and phosphorus removal efficiencies reached to 71 and 74% in run3 respectively. Effluent concentrations of TKN, Tot.P, NH4 and NO3 were found as 3.8, 3, 1 and 2.5 mg/l respectively.

摘要

在一个填充床柱中研究了营养物质的去除情况，该填充床柱通过改变曝气期和非曝气期来运行。在长曝气期获得了良好的氮和磷去除效率。在运行3中观察到最高的硝化效率，因为曝气期足以进行硝化作用。由于在好氧阶段同时进行反硝化作用，在循环过程中NO3浓度没有显著变化。在运行3中，氮和磷的去除效率分别达到71%和74%。发现总凯氏氮、总磷、NH4和NO3的出水浓度分别为3.8、3、1和2.5mg/l。
