| 摘 要： | 低碳氮比生活污水由于碳源不足,采用传统A/O工艺处理难以出水达标.采用改进的ABR-生物接触氧化工艺对低碳氮比污水进行实验,通过优化运行参数,合理调配碳源,提高碳源利用率,确定了不同m(COD)/m(N)条件下该工艺对污水的处理效果.研究结果表明:改进的ABR-生物接触氧化工艺能有效提高碳源利用率和脱氮效率；在水力停留时间为10h,混合液回流比为2.5,温度为30℃时,系统碳源利用率和TN去除率达到最高；在不同m(COD)/m(N)条件下,TN去除率随着m(COD)/m(N)的减小而迅速降低.当进水m(COD)/m(N)为2～4时,TN去除率低于60％,处理效果不理想:当进水m(COD)/m(N)约为5时,TN去除率达到71.3％,出水TN质量浓度小于20 mg/L,满足排放标准要求；当m(COD)/m(N)为6～7时,TN去除率大于80％,出水TN质量浓度小于15 mg/L.
