摘　　要：反硝化脱氮除磷技术与传统脱氮除磷方式相比,能够在缺氧段实现同步体脱氮除磷,具有节约碳源,减少能源消耗、污泥产量低等优点。简要概述了反硝化除磷的机理,总结并分析了碳源种类、碳源浓度、电子受体、温度、p H值、水力停留时间和污泥浓度等影响因素对反硝化脱氮除磷技术的影响。Compared with traditional nitrogen and phosphorus removal methods,denitrifying phosphorus removal technology can achieve simultaneous nitrogen and phosphorus removal in anoxic phase,it has the advantages of saving carbon source,reducing energy consumption and low sludge production.In this paper,the mechanism of denitrifying phosphorus removal was summarized;the influence of carbon source type,carbon source concentration,electron acceptor,temperature,pH value and hydraulic retention time on denitrifying nitrogen and phosphorus removal technology was analyzed.
