| 中文摘要 |
| 简捷硝化-反硝化过程处理焦化废水具有去除负荷高、出水浓度低、可节省反硝化碳源等优点.试验表明,当系统进水COD、NH3-N和TN浓度分别为1204.8、274.3和443mg/L,系统总水力停留时间为26.2h时,系统出水COD、NH3-N、NO2--N、NO3--N和TN浓度分别为36.3、12.1、9.25、2.46和44.4mg/L.试验结果还证明本文所采用的系统确实处于简捷硝化-反硝化状态. |
| 英文摘要 |
| A shorttened nitrification-denitrification system has been found to have the advantages such as high removal of loading, low COD and NH3-N concentrations in effluent and less requirement for carbon in denitrification. When the influent COD, NH3-N and TN concentrations are 1204.8, 274.3 and 443mg/L, respectively (HRT=26.2h), the effluent COD, NH2-N, NO3-N and TN are 36.3, 12.1, 9.25, 2.46 and 44.4mg/L, respectively. It was also showed in this paper that the system used in this study indeed followed a shorttened nitrification-denitrication pathway. |
