摘　　要：如今,城市污水的碳氮、碳磷质量比持续下降,在低C/N污水的处理过程中,生物处理工艺的反硝化阶段存在着碳源的竞争,而投加外加碳源是一种常见的提高脱氮除磷效率的手段,目前的缓释碳源主要分为两大类:一类是传统的液体碳源;另一类为新型碳源。综述了各类缓释碳源的优缺点和研究现状,以及在脱氮除磷工艺中实际应用存在的问题。Nowadays,the mass ratio of carbon to nitrogen and carbon to phosphorus in urban sewage continues to decline.During the treatment of low C/N sewage,there is competition for carbon sources in the denitrification stage of the biological treatment process,and adding the additional carbon source is a common means of improving the efficiency of denitrification and phosphorus removal,the current slow release carbon source is mainly divided into two categories:one kind is the traditional liquid carbon source,the other is new carbon source.In this paper,the advantages and disadvantages of various types of sustained-release carbon sources and their research status were reviewed,as well as the problems existing in practical application of nitrogen and phosphorus removal.
