| 摘 要： | 为系统研究厌氧污泥回流比对生物除磷效果的影响,以实际生活污水作为研究水样,研究不同污泥回流比R在厌氧段对COD（化学需氧量）、N（氮）、P（磷）的去除效果;深入研究污泥回流比对生物强化除磷代谢过程的影响。结果表明,在厌氧环境中,污泥回流比对NH4＋-N（氨氮）的去除没有明显影响,但对硝态氮、TP（总磷）、COD的去除影响较大。最佳回流污泥比应控制在60%到80%左右,在这两个工况下,PAOs（聚磷菌）释磷量能达到24.13 mg/L,这样能使PAO在厌氧池有效地利用碳源,充分释磷,从而提高除磷效率,同时应控制最佳厌氧有效时间为2到3个小时,如果厌氧时间过长或者过短都对PAO释磷产生一定的负作用。

| Abstract: | For the systematic study of anaerobic sludge recycle ratio effect on biological phosphorus removal,this paper took real-life pollution water as a water sample to research different anaerobic sludge recycle ratio of COD,N,P removal effect,and to do an in-depth study of sludge reflux ratio for enhanced biological phosphorus removal metabolism processes.The results showed that there is no significant effect of the reflux ratio on the removal of NH+4-N when the sludge in the anaerobic environment,but it has a g... |
