| 摘 要： | 采用AAO泥水回流工艺处理焦化废水，研究了进水碳氮比（C／N）对COD、氨氮及TN去除率的影响。研究表明，进水碳氮比（C/N）在12—25范围内，厌氧滤池COD去除率和氨化率分别达到37％和30％；缺氧进水碳氮比（C／N）控制在5．3-11．9范围内，MO泥水回流系统去除COD与氨氮效果的影响不明显，平均去除率分别为89．6％和95．2％；缺氧进水碳氮比（C/N）控制在7．5～8．6范围内，系统具有较好的TN去除率，平均值为72．2％。出水COD和NH3-N均能够达到污水综合排放标准中的二级标准。

| Abstract: | The coking wastewater was treated by A/A/O process with the sludge and wastewater back to anoxic tank from the MBR.The influence of C/N ratio on COD\NH3-N\TN removal by A/A/O process was studied.The results of the test showed that,when C/N ratio was 12-25,the removal of COD and the ammonification rate of NH3-N in anaerobic reactor were 37% and 30%,respectively;the removals of COD and NH3-N were not influenced by influent C/N ratio(5.3-11.9) in anoxic tank,and the average removals of them were 89.6%,95.2%,re... |
