摘要
利用中试规模实验装置,探讨了现有活性污泥工艺改造成间歇曝气生物脱氮工艺的实践中,碳氮比(C N)对废水生物脱氮效率、脱氮反应速度的影响,分析了脱氮容量,确定了所需外加碳源量。
In this study,to achieve nitrogen removal,an intermittent aeration pilot plant was applied to upgrade existing activated sludge system.Through the test,the impacts of C/N ratio on nitrogen removal efficiency and denitrification rate were investigated,and denitrification capacity was discussed to determine the demand of external carbon source.
