摘　　要：目前,我国大部分生活污水、城市污水和部分工业废水中有机物含量偏低,呈现低C/N的特征,不利于大多数异养反硝化细菌的生物脱氮。因此,需要筛选适应低C/N废水的反硝化细菌,并应用于实际低C/N废水的脱氮处理。本文着重介绍了适应低C/N反硝化细菌的脱氮性能和适应机制,以及利用反硝化与其他技术相耦合的组合脱氮技术在处理实际低C/N废水中的应用。最后,探讨了处理低C/N废水面临的挑战和发展前景。At present,the content of organic matter in most domestic sewage,municipal sewage and some industrial wastewater is low,as the characteristic of low C/N,which is not conducive to the most heterotrophic denitrification bacteria.Therefore,it is very urgent to screen some denitrifying bacteria suitable for low C/N wastewater and be applied to the actual denitrification treatment of low C/N wastewater.This paper focuses on the denitrification performance and mechanism of low C/N denitrifying bacteria,and the application of denitrification coupled with other technologies in the treatment of actual low C/N wastewater.Finally,the challenges and prospects of low C/N wastewater remediation are discussed.
