摘要
针对生活污水的特点，采用曝气生物滤池技术对不同碳源（甲醇、乙酸钠和葡萄糖）条件下的生物脱氮效果进行了试验研究。结果表明，在C／N为3：1～4：1、滤速为1．0m／h时，不同碳源对缺氧生物滤池的生物脱氮效果影响很大，其中以甲醇和乙酸钠作为外碳源时，脱氮效果较好，而以葡萄糖为碳源时的脱氮效果明显逊于二者。
The purpose of this research is to study the nitrogen removal rate of municipal wastewater after the treatment of biological aerated filter （BAF） in the condition of different carbon resources （CH3OH, CH3COONa,C6H12O6）. The research shows that when C/N is 3 ： 1 -4 ： 1, velocity is 1.0 m/h, the additional carbon resource has a significant effect on denitrification rate in anoxic filter： The bio-chemical characters of CH3OH and CH3COONa are similar when they are used as the carbon resource, and these two resources result in quite efficient denitrification. However, using C6H12O6 as the additional carbon resource leads to lower nitrogen removal rate when compared with these two mentioned sources.
