摘要/Abstract

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1.0 m/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。

Abstract: 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.
