摘　　要：反硝化是在反硝化细菌的作用下,以硝酸盐作为最终电子受体而进行的无氧呼吸过程。从污水脱氮的角度论述反硝化在污水脱氮中的作用、污水脱氮的机理、污水脱氮过程中反硝化作用的影响因素等。从反硝化的角度出发,论述了反硝化细菌的类群、反硝化作用的机理、反硝化细菌细胞中参与反硝化过程的关键酶。另外,还论述了近年来发现的有氧反硝化细菌、自养反硝化细菌及反硝化除磷细菌等方面的研究进展。Denitrification plays an important role in wastewater treatment systems for the reason that the nitrate or nitrite was reduced, and some gases such as NO, N2O or N2 were released. The application of denitrification in wastewater, the mechanism of denitrification, and the effect factors of denitrification were introduced in this paper. The communities of Denitrifying bacteria, and some key enzymes of denitrification were also introduced. The discovery of aerobic denitrifying bacteria, autotrophic denitrifying bacteria, and denitrifying Phosphorus-removing Bacteria were also mentioned in this paper.
