Abstract: In recent years，as people’s understanding of wastewater biological nutrient removal process were improving，some new wastewater treatment technologies were generated. The mechanisms，influencing factors and process characteristics of CANDO，BioCAST，UAASB，A-CFBBE，TCFBBR，A2N-IC for nutrients removal were highlighted in this article. Comparing with traditional technology，the characteristics of the new technologise were discussed. Finally gives a prospect of biological nutrient removal technology，pointing out that the developing direction for future wastewater treatment process should be economic，efficient and low energy consumption.

Key words: biological nutrient removal, shortcut nitrification-denitrification, denitrifying phosphorus removal

摘要： 随着人们对污水生物脱氮除磷过程认识的不断深入，产生了一些新的处理工艺。本文重点介绍了耦合好氧-缺氧N2O分解工艺（CANDO）、同时去除含碳有机物及氮磷营养物质新工艺（BioCAST）、上流式厌氧-缺氧污泥床工艺（UAASB）、厌氧循环流化床工艺（A-CFBBR）、双循环流化床生物反应工艺（TCFBBR）、双污泥反硝化诱导结晶工艺（A2N-IC）等6种新工艺的原理、影响因素和工艺流程特点。通过与传统工艺的相比较，对新工艺的特性进行了探讨。最后展望了污水脱氮除磷技术的发展趋势，指出经济、高效、低能耗的可持续脱氮除磷工艺是污水处理未来的发展方向。
