废水反硝化除磷影响因素的分析

介绍了反硝化除磷技术的原理、主要影响因素和实现反硝化除磷的新途径。国内外对碳氮质量比，亚硝酸盐对反硝化除磷的影响的研究结果存在争议。本文对有争议和有待于深入研究的影响因素作了总结。目前，关于在工艺中如何实现反硝化除磷的研究有了突破性进展。这些新途径有：AOAO—SBR工艺、好氧颗粒污泥法。反硝化除磷技术已从基础性研究发展到了工程应用阶段，随着微生物学及生物化学的进一步发展和研究的进一步深入．人们对反硝化除磷机理、影响因素将有更加清楚的认识。这些都将进一步促进反硝化除磷技术的应用推广。

Research on Influencing Factors of Denitrifying Phosphorous Removal in Wastewater Treatment

In the paper,fundamental theories of denitrifying phosphorous removal technology, major influencing factors and new methods for denitrifying phosphorous removal were introduced. There were disputes on the research results of the influence of C/N and nitrite on denitrifying phosphorous removal from home and abroad. The disputes and influencing factors to be further studied were summarized in this paper. At present, there were breakthroughs in the research of how to realize denitrifying phosphorous removal. The new methods were AOAO-SBR and aerobic granular sludge process. Denitrifying phosphorous removal has developed from basic research to project application. With the further development and research of microbiology and biochemistry, the knowledge of the theories and influencing factors of denitrifying phosphorous removal will be more clear, which will further promote the application of denitrifying phosphorous removal technology.
