摘　　要：与传统好氧除磷技术相比,反硝化除磷技术具有一碳两用、节约碳源、减少曝气量以及降低产泥量等优势。文章综述了以硝态氮和亚硝态氮为电子受体的反硝化除磷技术在菌群培养方式、脱氮除磷效率和微生物群落结构等方面的技术特点及相关工艺的研究进展,总结亚硝态氮浓度抑制反硝化缺氧吸磷阈值的相关研究。最后对反硝化除磷工艺的发展前景进行展望。Compared with the traditional aerobic phosphorus removal technology,denitrifying phosphorus removal technology has the advantages of one carbon with two functions,saving carbon source,reducing aeration and reducing sludge production.This paper summarizes the technical characteristics and research progress of denitrifying phosphorus removal technology with nitrate and nitrite as electron receptors in terms of flora culture mode,nitrogen and phosphorus removal efficiency and microbial community structure,and summarizes the related research on the inhibition of denitrifying anoxic phosphorus absorption threshold by nitrite nitrogen concentration.Finally,the development prospect of denitrifying phosphorus removal process is prospected.
