| 中文摘要 | 对传统A/O工艺和升流缺氧/好氧(UA/O)脱氮工艺处理城市生活污水的效果进行了对比研究。结果表明,在HRT、SRT、DO、pH值、混合液回流比、污泥回流比、好氧段MLSS等运行参数相同的情况下,A/O和UA/O两组工艺对COD的去除效果相当,平均去除率分别为88%和89%;对NH3-N的去除效果也相差不大,平均去除率分别为90%和92%;但UA/O工艺对TN的去除效果更好,平均去除率为57%,比A/O工艺高了12%。另外,在进水水质波动较大的情况下,UA/O工艺的抗冲击负荷能力更强,出水水质更稳定。; The efficiencies of up-flow anoxic /oxic( UA /O) and conventional A /O process for municipal domestic sewage treatment were studied comparatively. The results showed that under the same operating parameters,such as HRT,SRT,DO,pH,mixed-liquor return ratio,sludge return ratio and oxic MLSS,the A /O process and the UA /O process had similar COD removal efficiencies,and the average COD removal rates were 88% and 89%,respectively. There was not much difference in NH3- N removal efficiency between the two processes,the average NH3- N removal rates were 90% and 92%,respectively. The UA /O process achieved 57% of the average TN removal rate,which was 12% higher than the A /O process. The UA /O process had stronger shock load resistance and more stable effluent quality when fluctuation in influent quality was large. |
