  • 摘要: 采用三级A/O工艺分段进水工艺处理低碳源生活污水,考察了进水流量分配比对系统去除有机物、硝化反硝化能力以及去除TN的影响。通过对水质指标沿程监测结果表明,不同流量分配比(4∶3∶3,5∶3∶2,6∶3∶1)对系统去除有机物及硝化效率影响不大,出水COD、氨氮分别均在30 mg/L、1 mg/L以下。但反硝化效果受流量分配比的影响较大,在流量比为5∶3∶2时,有效利用原水中碳源进行反硝化,反硝化效果最好。在流量比为5∶3∶2的情况下,TN出水为5.7 mg/L去除率为82.9%,优于流量分配比为6∶3∶1和4∶3∶3时的脱氮效果。总体而言,分段进水工艺在对碳源的有效利用及能耗节省方面优于单点进水。
    Abstract: Three-stage step-feed A/O system was applied to treat sewage with low carbon source,experiments were carried out to investigate the effect of different influent flow distribution ratios on organic matter,nitrification and denitrification removal efficiency. It was showed that different flow distribution ratios (4∶3∶3, 5∶3∶2, 6∶3∶1) had a little effect on organic matter removal and nitrification efficiency, the effluent of COD,NH3-N were below 30 mg/L and 1 mg/L, respectively. But denitrification efficiency was considerably affected by the different flow distribution ratios. When flow distribution ratio was 5∶3∶2, carbon source of sewage was effective used, and the system achieved the optimum efficiency of denitrification. When flow distribution ratio was 5∶3∶2, the effluent TN was 5.7 mg/L with 82.9% removal efficiency,which was better than the flow distribution ratios of 6∶3∶1 and 4∶3∶3. In summary, the step-feed system is superior to single point feed system in the aspect of effective usage of carbon sources and energy saving.
