生物脱氮除磷研究进展

Research Progress on Biological Denitrification and Phosphorus Removal

从传统生物脱氮除磷工艺存在的问题及其产生的原因出发,将生物脱氮除磷新工艺分为基于不同营养类型微生物独立生长、基于新机理、基于处理设备高度简化三类,并对前两类做了详细介绍,同时对今后生物脱氮除磷技术的发展进行了展望。

Biological technology of denitrification and phosphorus removal has been focused on in wastewater treatment field in recent years. From the problem and its cause for the conventional denitrification and phosphorus removal technology, advanced technology of denitrification and phosphorus removal can be divided into three kinds： on the basis of the independent growth of different microbes,on the basis of the advanced mechanism and on the basis of the least construction. This paper introduces the first two kinds of technology in detail and generalizes the development direction of biological technology of denitrification and phosphorus removal.
