摘　　要：传统的生物脱氮除磷技术效率低下,导致氮、磷去除率不达标,是造成水体的富营养化的主要原因。概述了传统生物脱氮除磷原理,分析了传统生物脱氮除磷工艺的不足,并介绍了反硝化除磷、同时硝化反硝化、短程硝化反硝化、厌氧氨氧化等几种生物脱氮除磷新技术的原理与典型工艺。最后对生物脱氮除磷技术的发展趋势进行了展望,指出经济、高效、低能耗的可持续脱氮除磷工艺是污水处理的发展方向。Because of the low inefficiency of traditional Nitrogen and Phosphorus removal process,it caused to the removal rate of Nitrogen and Phosphorus not standard,which is the main reason of water eutrophication.This article summarizes the mechanism of traditional Nitrogen and Phosphorus removal process firstly,analyzes its deficiencies of and introduces several new removal processes such as denitrifying dephosphataion,Simultaneous nitrification and denitrification,shortcut nitrification-denitrification and anaerobic ammonium oxidation,it also expatiates those mechanism and typical process.Finally gives a outlook of these advanced processes,pointing out that the trend of new nitrogen and phosphorus is economic,efficient,low energy consumption and sustainable.
