C/N值对A/O生物滤池性能影响分析王跃鹏1,陈东宁2,裴 欣2,刘 强2(1.沈阳市自来水总公司给水设备维修服务中心,辽宁沈阳110036;2.沈阳建筑大学市政与环境工程学院,辽宁沈阳110168):通过分析C/N值对A/O生物滤池性能的影响,为污水回用提供有效的处理工艺及参数。对模拟污水进行动态试验,研究不同的C/N比值对氨氮、总氮及COD去除效果的影响。试验表明,在当A/O生物滤池C/N比值为4.6~5.5、水力负荷为2~3m/h,回流比为1∶2,好氧段气水比为1∶3时,原水中的NH3-N、TN和COD都得到了较好的去除,去除率最高分别能达到92.1%,92%,95%。A/O生物滤池能够有效地去除污水中的氨氮、总氮及COD等,在适当的C/N比值的情况下,可有效提高去除效率,降低运行成本。:A/O生物滤池;C/N值;硝化;反硝化:X703
