| 摘 要： | 利用厌氧/缺氧(A/A)SBR,试验研究了选择和富集反硝化除磷菌(DPB)的条件.结果表明,采用电子供体和电子受体充分分开的两段进水方式运行,当厌氧段进水COD与缺氧段投加硝酸盐质量浓度为300 mg.L-1、50 mg.L-1,pH值约为7.0时,DPB可快速成为系统中的优势菌群,系统可达到良好的反硝化聚磷效果;将前述系统改变为一段进水方式运行后,系统仍具有良好的反硝化聚磷效果.在进水磷浓度同为20 mg.L-1下,在缺氧段投加磷的运行方式比在厌氧段投加磷的运行方式更能提高系统的除磷能力.

| Abstract: | An anaerobic/anoxic sequencing batch reactor(A/A SBR) was conducted to investigate the conditions for screening and enrichment of denitrifying phosphorus removing bacteria(DPB).The results showed that,when the concentration of COD in influential of anaerobic stage,the concentration of (NO~-_3-N) in influent of anoxic stage and pH value were 300(mg/L),50(mg/L) and 7.0 respectively,DPB could become dominant populations quickly in the system in two-time feeding mode,and the reactor performed well for denitrify... |
