摘　　要：传统的生物脱氮工艺对于低（超低）ＣＯＤ／ＮＨ４＋条件下废水　的脱氮效果很差，甚至没有脱氮效果，因为传统的生物脱氮工艺在反硝化过程中需要大量的　电子供体。亚硝酸型硝化和厌氧氨氧化有机结合构成新型的生物脱氮工艺，为低碳（超低碳　）高浓度含氮废水提供了一种崭新的生物脱氮工艺。但其间的反应机理、控制条件等都需进　一步的研究和探讨。Traditional biological processes, which need a lar ge number of electrons during the denitrification process, are of low efficiency , even no effect on ni trogen removal in the condition of low (or super low) COD/NH + 4. The combin ation between shortcut nitrification and anaerobic ammonia oxidation provides a new bi ological process of nitrogen removal, especially to the waste water with high ni trogen concentration and low (or super low) carbon resources． However, the reac tion mechanism and the controlling factors need further research and discussion ．
