废水生物脱氮处理方法研究

Study on method of biological nitrogen removal from wastewater

氨氮是水体富营养化的主要成分之一,本文介绍污水生物脱氮技术原理,并对比介绍生物脱氮法几种主要工艺的基本原理、工艺特性和研究进展,并结合国内外的生物脱氮最新研究进展,对同时硝化反硝化的形成机理及其对SBR工艺、氧化沟、MBR工艺等的应用进行了分析。最后指出生物脱氮处理方法的研究前景。

Nitrogen(N) is one of the key elements of eutrophication in waterways.Firstly,the paper has introduced the technical principle of biological nitrogen removal and has compared the principle、technical characteristics and research progress of the major techniques(AB technique、SBR technique、A2/O technique、Oxidation Ditch method、BAF technique、MBR technique) of biological nitrogen removal.Combined with new research progress,the mechanism of simultaneous nitrification and denitrigication and the application of the some techniques(SBR、Oxidation Ditch、MER) are analyzed.Lastly,the further studies are proposed.
