摘　　要：从生物除磷脱氮机理出发,主要论述了新型或改良生物除磷脱氮工艺,包括ECOSUNIDE工艺、多箱一体化活性污泥工艺、两段SBR双污泥系统短程硝化反硝化除磷脱氮工艺等,并展望了生物除磷脱氮技术发展的趋势及前景。There are some disadvantages in traditional activated sludge processes,such as competition for substrate,differences of sludge age,and high demand for carbon source,which lead to poor efficiency of nutrient removal.Some new technologies are developed to solve these problems in order to improve the efficiency of nutrient removal with low cost.In this paper,from the mechanisms of biological nutrient removal,few new technologies are introduced,such as ECOSUNIDE technology,multi-tank bioreactor integrated wastewater treatment,two-stage and double-sludge-system SBR for shortcut nitrification-denitrification,A/O process with fixed media,SBMBR,ANAMMOX-MBR.Development tendency and perspectives are also put forward.
