污染水体脱氮工艺中外加碳源的研究进展

Advances in the polluted water denitrification by using additional carbon sources

碳源是传统生物脱氮过程中的一个重要因素,当水体中碳氮质量比过低时,往往需要投加外加碳源作为电子供体,以保证反硝化反应的顺利进行。作者主要对污水脱氮过程中添加不同外加碳源后,对氮的去除率、工艺的优缺点及成本等方面进行了总结。

Carbon source is an important factor for water denitrification. When C/N ratio in water additional carbon source is always used as electron donor,so that denitrification can be carried through After adding different additional carbon sources in the process of wastewater denitrification,the denitrification, the advantages and disadvantages of this technology,cost,etc, are summarized.
