| 摘 要： | 基于模拟河道反应器，考察了曝气充氧及人工造流技术对污染水体的修复效果。结果表明，河道本身具有一定的自净能力，自然运行条件下对COD、TP、NH3-N和TN的去除率分别为7.44%、4.88%、5.70%和10.60%。通过对模拟河道进行曝气充氧，最佳气水比条件下对COD、TP、NH3-N和TN的去除率分别为15.33%、10.45%、6.78%和21.18%。在曝气基础上通过设置人工阻流板，对COD、TP、NH3-N和TN的去除率分别为26.82%、16.07%、9.51%和23.80%。结果初步显示，通过曝气充氧和人工造流技术的集成应用研究，对污染水体具有明显有效的修复作用。 |

| Abstract: | The effect of remediation of polluted water by aeration and artificial streaming technology was studied based on the simulated river reactor.The results showed that the river had the capacity of self-purification.Under the natural operating condition,the removal rates of COD,TP,NH3-N and TN were 7.44%,4.88%,5.70% and 10.60%,respectively.With the best air to water ratio,the removal rates of COD,TP,NH3-N and TN were 15.33%,10.45%,6.78% and 21.18%,respectively.By adding the artificial spoiler,the removal rates of COD,TP,NH3-N and TN were 26.82%,16.07%,9.51% and 23.80%,respectively.Integration of aeration and artificial streaming technology was effective for remediation of polluted water. |
| Keywords: | simulated river reactor aeration artificial streaming technology remediation of polluted water |
