摘　　要：短程硝化和反硝化除磷耦合工艺具有耗能低、节省碳源,污泥产率少等优势,如何优化调控该工艺,使其两者耦合协同,实现高效稳定运行是该工艺实际应用的难点。研究表明,在不同的工艺中,反硝化除磷功能菌的除磷机理以及EPS所起的除磷作用强弱存在差异。在整个耦合工艺运行过程中,pH.溶解氧.HRT以及硝化液回流比等的调控是否适宜,关系到耦合工艺的整体运行效果。基于已有研究报道,分析讨论了两者耦合的机理、反硝化除磷菌属、调控因素及其研究进展。The coupling process of short-cut nitrification and denitrification for phosphorus removal has the advantages of low energy consumption,lesscarbon source and lss sludge output,etc.However,the optimization of the process to realize efficient and stable operation is the botleneck for itspractical aplication.Previous research results showed that the mechanism of phosphorus removal by denitrifying phosphorus removal bacteria and therole ofEPS in phosphorus remnoval were different in different processes.The overall performance of the coupling process is significantly affcted by thecontrol of pH,dissolved oxygen concentration,hydraulic retention time(HRT)and nitrfication liquid reflux ratio.Based on these existing researchreports,herein the advances on coupling mechanism,denitrifying phosphorus removal bacteria,regulatpry factors were discussed.
