中文摘要：

采用倒置A2/O法同时处理城市污水与渗滤液去氮除碳。结果表明,当渗滤液混入量较低时,对城市污水碳源基本不构成影响;水力停留时间是最显著影响因子;理论最佳工况是：水力停留时间为9 h,溶解氧质量浓度为2 mg/L,外回流比为0.8,内回流比为2。此时,COD、NH3-N和TN浓度均可稳定地达到《城镇污水处理厂污染物排放标准》（GB18918-2002）一级A标准,平均去除率分别为77.4%、97.2%和62.4%。

英文摘要：

Reversed A2/O process is used to treat municipal wastewater and nitrogen and carbon removal in the consolidated treatment of landfill leachate.The results show that HRT is the key factor for nitrogen and organic removal efficiency by orthogonal experiment.In conditions of HRT 9 h,DO 2.0 mg/L,R 80%,r 200%,the effect of organic and nitrogen removal achieves the optimal synchronization and the average removal rate of COD,NH3-N,TN can reach 77.4%,97.2% and 62.4% respectively,meanwhile the effluent concentration can also reach standard level A of ＂Discharge standard of pollutants for municipal wastewater treatment plant＂A-level standard.
