Research progress in the denitrification technique in biological aerated filter

曝气生物滤池(BAF)有着良好的脱氮效果,近年来曝气生物滤池与新型脱氮理论的结合成为研究的热点。详细阐述了传统脱氮理论与新型脱氮理论在曝气生物滤池中的应用,并介绍了其影响因素。对曝气生物滤池的脱氮前景进行了展望,对存在的问题进行了初步分析。指出将新型脱氮理论运用于曝气生物滤池,对于开发低耗高效的脱氮工艺是个非常好的思路,具有广阔的发展前景。

Biological aerated fiher（BAF） has good effect on denitrification. The combination of BAF and new deni-trification theories has become a research hotspot in recent years. The application of traditional denitrification theo-ries and new denitrification theories to BAF is expounded in detail, and their influencing factors are introduced. Theresearch prospect of the denitrification in BAF is predicted and the existing problems are analyzed preliminarily. It ispointed out that applying new denitrification theories to BAF for the exploitation of low-consumption and high-efficiency denitrification technology is a good idea and has broad development prospects.
