解析多级ao-mbr工艺在生活污水脱氮除磷中的应用

Application of Multi-stage AO-MBR Process in Nitrogen and Phosphorus Removal of Domestic Sewage

传统工艺在处理氮磷含量较高的生活污水时效果往往不理想;因此,研究人员在解决生活污水处理超标排放的问题时,结合氮磷在生活污水中主要以氨氮、硝态氮、有机氮等形式存在的特点,研发出多级AO-MBR工艺。文中将对生活污水处理工艺现状进行分析,阐述脱氮除磷的基本原理,探究多级AO-MBR工艺在生活污水脱氮除磷中的应用。

The effect of traditional process in the treatment of domestic sewage with high nitrogen and phosphorus content is often not ideal;therefore,researchers in solving the problem of excessive discharge of domestic sewage treatment,combined with the characteristics of nitrogen and phosphorus mainly in the form of ammonia nitrogen,nitrate nitrogen,organic nitrogen,etc.,developed a multi-stage ao-mbr process.This paper analyzes the status of domestic sewage treatment process,expounds the basic principle of nitrogen and phosphorus removal and explores the application of multi-stage ao-mbr process in domestic sewage nitrogen and phosphorus removal.
