摘要
碳源作为反硝化过程的电子供体,是影响反硝化过程的重要影响因素。针对污水中碳氮比偏低时,需要考虑使用外加碳源提供反硝化电子供体。本文对现有的污水反硝化过程中外加碳源的种类及脱氮效果进行了对比总结。
Carbon source as the electron donor,is the main limiting factor of denitrification rate.When C/N ratio in water is very low,it is therefore reasonable to supply external carbon to improve the denitrification process.Different additional carbon sources in the process of wastewater denitrification and the efficiency of denitrification were summarized in this paper.
