反硝化除磷过程中影响因素的研究进展

Research and development on the influencing factors in the process of denitrifying dephosphorization

对近年来国内外关于反硝化除磷的原理及其影响因素进行了综述。讨论并分析了NO3-、NO2-、碳源、污泥龄、溶解氧、碳氮比和碳磷比对反硝化除磷的影响,并指出了反硝化除磷作为一种绿色可持续发展污水处理工艺的发展方向。

The principle and influencing factors of denitrifying dephosphorization both in China and abroad in re- cent years are summarized. The effects of NO3-, NO2-,carbon source, sludge retention time, dissolved oxygen, C/N and C/P on denitrifying dephosphorization are discussed and analyzed. And the development direction of denitrify- ing dephosphoization as a green and sustainable development of sewage treatment process is oointed out.
