| 摘 要： | 在前期的模拟试验中曾预测，磷回收介入生物营养去除（BNR）工艺，不仅有利于提高生物除磷效果，而且可以降低生物除磷所需的进水COD／P值。为了证实这一预测，以传统A^2／O工艺作为主要流程进行试验。结果表明，当侧流比达到20％时，满足排放标准（TP〈1mg／L）的最低COD／P值从原来的35降低到25，此时对磷的有效回收率为34％。这意味着，在生物除磷过程中可节约25％～30％的碳源。

| Abstract: | A previous modeling study predicted that phosphorus removal and recovery can be combined in a biological nutrient removal(BNR) process,which would benefit for improving the effluent quality of bio-phosphorus removal and for lowering the ratio of the influent COD/P required for bio-phosphorus removal.To verify this modeling prediction,an experiment using traditional A~2/O process was carried out.The experimental results are quantitatively in agreement with the modeling prediction.When the stripping ratio reaches 20%,the minimal COD/P ratio to satisfy the effluent standard(TP<1 mg/L) can be lowered from 35 to 25 at a phosphorus recovery efficiency of 34%.This suggests a COD saving of 25%-30% in bio-phosphorus removals. |
