| 摘 要： | 介绍了生物除磷的Comeau-Wentzel模式,这种模式在某种程度上能够解释生物除磷的机理,因此PAOs释磷和吸磷的Comeau-Wentzel模式被借鉴用以分析反硝化除磷的机理。在此基础上,总结近年来反硝化除磷的研究成果,阐述电子受体NOx-对反硝化除磷的影响:在厌氧区,只有当NO3-浓度较高时,厌氧释磷的效果才会受到影响;在缺氧区,硝酸盐能够做为反硝化除磷的电子受体,但硝酸盐浓度过高会明显降低磷去除速率;亚硝酸盐同样能够作为反硝化除磷的电子受体,前提是亚硝酸盐不超过临界抑制浓度。

| Abstract: | The Comeau-Wentzel model on biological phosphorus removal is described.It is suggested that this model should be applied in denitrifying dephosphatation.According to the latest research finding on denitrifying dephosphatation,the effect of electron acceptors on denitrifying dephosphatation is discussed in details.In the presense of lots of nitrate,anaerobic phosphorus release would be decreased.Nitrate can be utilized as electron acceptor in denitrifying dephosphatation,but the velocity of phosphorus uptake... |
