摘　　要：纤维式组合填料A^2/O工艺体系中当采用甲醇、葡萄糖和乙醇作为系统碳源时,得到甲醇作为外加碳源时,系统运行效果最佳,出水TN、NH_3—N、TP和COD质量浓度分别为14.99、18、1.04、64mg/L,TN、NH_3—N、TP和COD的去除率分别为85.81%、81.43%、86.21%和84.58%.研究三种碳源对反硝化的响应时间得到,甲醇的反硝化响应速度最快,硝酸盐氮被完全去除的时间为20 min.对A^2/O工艺的碳源补充分析研究得到,当外加碳源(甲醇)投加比例为1∶2∶0,投加量为400 mg/L时,A^2/O工艺运行效能最佳,得到TP、TN、NH_3—N和COD的去除率分别是86.64%、87.84%、94.87%和89.18%,出水质量浓度分别为0.46、15.21、7.18、42 mg/L.To solve the carbon source problem of fiber carrier media A2/O process for urban sewage, the methanol was the best one on nutrients removal when methanol, glucose and alcohol were used as carbon sources. The results showed that the effluent concentration of TN, NH3--N, TP and COD were 14.99, 18, 1.04, and 64 mg/L. The removal rate of TN, NH3-N, TP and COD were 85.81%, 81.43%, 86.21% and 84.58%. The response time of the three kinds of carbon sources for denitrification was studied. The results showed the methanol have fastest response. The NH3-N was removed completely for 20 minutes. The analysis of the carbon sources for the A2/O process showed that when dosing method of methanol was 1： 2： 0, addition concentration was 400 mg/L, the A2/O system run well. The re- moval rate of TN, NH3--N , TP and COD were 86.64, 87.84%, 94.87% and 89.18%, and the effluent concentration of TN, NH3--N, TP and COD were 0.46, 15.21,7.18 and 42 mg/L.
