摘要
短程反硝化除磷是以亚硝酸盐为电子受体完成缺氧吸磷的一种新型强化生物除磷工艺,对低碳源污水有着强力的脱氮除磷效果.文中介绍了短程反硝化除磷的原理,综述了进水碳源、亚硝酸盐、游离亚硝酸、温度、p H和运行方式等几种因素对短程反硝化除磷的影响,认为在短程反硝化除磷工艺中进水碳源和温度的影响与普通的强化除磷相似、污泥的驯化能够有效提高对亚硝酸盐毒害的耐性、双污泥连续式反应器的脱氮效果差,并对短程反硝化除磷的工程应用提出了建议.
Partial denitrifying dephosphatation is a new type of enhanced biological phosphorus removal process that uses nitrite as an electron acceptor to complete anoxic phosphorus uptake.It has a strong effect on removing nitrogen and phosphorus from low-carbon source waste water.The principle of partial denitrifying dephosphatation is introduced and the effects of various factors such as influent carbon source,nitrite,free nitrous acid,temperature,pH,and operation mode on partial denitrifying dephosphatation are reviewed.It is considered that the influent carbon source and temperature on partial denitrifying dephosphatation are similar to ordinary enhanced biological phosphorus removal;the domestication of sludge in partial denitrifying dephosphatation can effectively improve the tolerance of nitrite poisoning.The denitrification effect of the double sludge continuous reactor in the partial denitrifying dephosphatation is poor.Suggestions for engineering application of partial denitrifying dephosphatation are also proposed.
