利用反硝化聚磷菌实现城市污水的脱氮除磷

Removal of Nitrogen and Phosphorus from Municipal Sewage Using DPBs

阐述了反硝化除磷的机理,对现有反硝化除磷工艺进行介绍,并进一步讨论了反硝化除磷的影响因素和未来发展新思路。利用DPBs进行反硝化除磷实现了污水处理的资源化和能源化,代表了当前污水处理可持续发展战略的发展趋势,成为目前脱氮除磷技术研究的热点和重点。

In this paper, the present process and the mechanism of denitrifying dephosphatation are introduced. Furthermore the factors affecting the effect of denitrifying phosphorous removal as well as new ideas for future development are discussed. By means of denitrifying phosphorus removal bacteria （ DPB ） for denitrifying dephosphatation, the municipal sewage is converted into resources and energy, which represents the development trend, as a sustainable strategy, for sewage treatment. It becomes the hot and key point of the present technical research on denitrifying dephosphatation.
