摘　　要：低碳氮比城市污水的高效低耗同步脱氮除磷是水污染防治的重点和难点问题,开发和应用低碳高效的脱氮除磷技术和工艺具有重要经济和环境效益。本文总结了同步脱氮除磷技术的发展历程,重点探讨了基于厌氧氨氧化强化的城市污水同步脱氮除磷新工艺和新技术,包括基于传统除磷与全程自养脱氮耦合工艺、反硝化除磷与厌氧氨氧化自养脱氮耦合工艺、部分厌氧氨氧化强化同步脱氮除磷等。其中基于部分厌氧氨氧化同步脱氮除磷的工程案例表明:短程反硝化耦合厌氧氨氧化可实现厌氧氨氧化菌的富集,同时解决低温对脱氮除磷性能的抑制。该技术利用原水碳源,在不同尺度的研究中均体现出深度的脱氮除磷效果。本文还比较了不同工艺的技术特点及工程应用前景,对未来研究的重点提出了展望,可为后续主流城市污水氮磷同步去除工艺的开发与优化提供参考。The high efficiency and low consumption simultaneous of nitrogen and phosphorus removal from low C/N ratio municipal wastewater is the key and tricky problem of water pollution control.The development and application of low carbon and high efficiency nitrogen and phosphorus removal technology possesses significant economic and environmental benefits.In this review,the developing processes of simultaneous nitrogen and phosphorus removal technology were summarized.The novel processes and technologies of simultaneous nitrogen and phosphorus removal treating municipal wastewater based on anaerobic ammonium oxidation(ANAMMOX)were discussed,including coupled of traditional phosphorus removal and full-step autotrophic nitrogen removal processes,coupled of denitrifying phosphorus removal and anammox autotrophic nitrogen removal processes and advanced simultaneous nitrogen and phosphorus removal processes based on partial anammox.Among them,the practices of simultaneous nitrogen and phosphorus removal process based on partial anammox showed that coupled of partial denitrification and anammox could realize the enrichment of anammox bacteria and solve the inhibition of low temperature on nitrogen and phosphorus removal performance.This technology has demonstrated advanced nitrogen and phosphorus removal efficiency on different scales using raw water carbon sources.In this review,the technical characteristics and engineering application prospects of different processes were compared,and the key points of future research were prospected,which could provide references for the development and optimization of the synchronous nitrogen and phosphorus removal process of mainstream municipal wastewater.
