| 摘 要： | 针对A2/O工艺在脱氮除磷方面存在的矛盾,以及生物难降解印染废水中碳源不足的问题,提出厌氧水解-分点进水倒置A2/O处理印染废水的新工艺。试验结果表明:新工艺仅利用2段生化处理过程,出水COD、BOD5、氨氮、TN、TP、色度分别可达77.12%、70.93%、96.59%4、5.52%、63.33%8、3.11%的平均去除率,分别比常规A2/O工艺提高16.01、27.85、3.92、8.851、9.89、0.65个百分点,显示厌氧水解-分点进水倒置A2/O工艺具有较好的污染物去除效果。 |
| 关 键 词： | 厌氧水解 分点进水倒置A2/O工艺 印染废水 |

| Abstract: | In view of the conflict between the nitrogen and phosphorus removal in A2O technique,as well as the problem of insufficient carbon source in the nonbiode gradable dyeing wastewater,the anaerobic hydrolysis-step feed in the inverted A2O technique was studied in textile wastewater treatment.The results showed that the removing rates of COD,NH4+-N,TN,TP,BOD5,chroma increased from 61.11%,92.67%,36.67%,43.44%,43.08%,82.46%,by the routine A2O technique to 77.12%,96.59%,45.52%,63.33%,70.93%,83.11% by the new techn... |
