| 摘 要： | 采用批式实验,以人工配水培养的好氧颗粒污泥为接种污泥,考察了DO浓度、碳氮比、污泥龄对序批式颗粒污泥系统同步脱氮除磷效果的影响。结果表明,DO通过渗透作用造成颗粒内部缺氧区大小变化进而从整体上表现出对系统同步脱氮除磷性能的影响,较低的DO浓度更有利于系统的稳定运行,当DO浓度控制在1mg/L左右时,颗粒污泥系统对COD、氨氮、总氮及磷酸盐的去除率均在90%以上;进水碳氮比减小,导致厌氧段胞内储存物质(PHB)的合成不足,造成好氧聚磷和反硝化聚磷对PHB的竞争,系统同步脱氮除磷性能下降;而序批式颗粒污泥系统泥龄的控制应从平衡排泥除磷以及保持足够颗粒污泥数量维持系统正常运行综合考虑进行操作。 |

| Abstract: | The aerobic granular sludge cultivated from synthetic municipal wastewater was used in the present batch experiment to determine the effects of the DO concentrations,C/N ratio,sludge retention time on the simultaneous phosphorus and nitrogen removal performance of the granular sludge SBR.The results showed that the influence of DO on the performances of simultaneous phosphorus and nitrogen removal in aerobic granular sludge SBR was exhibited by compressing anoxic zone in granule.Lower DO contributed more be... |
