| 摘 要： | 通过对长沙某污水处理厂进行24 h水质、水量的监测,分析了其Carrousel氧化沟处理污水的特点.从脱氮的原理出发,结合流速、溶解氧等运行参数的考察,发现造成脱氮效果不好的主要原因是沟内缺少厌氧区段,提出改进措施,从宏观改善流体的流动人手,以达到调控溶解氧传递的目的,既而促进微观的硝化与反硝化反应,提高污水处理效果. |

| Abstract: | The variations of water quality and flux in 24 h of a wastewater treatment plant in Changsha are monitored. The characteristic of the Carrousel oxidation ditch is obtained. By analysis, it is found that the reason for the less removal of nitrogen in this old plant comes from the absence of anaerobic region in the oxidation ditch. Then corresponding methods are presented. We can improve nitrification and denitrification by controlling dissolved oxygen transfer,flow pattern and flow velocity in the Carrousel oxidation ditch. |
| Keywords: | Carrousel oxidation ditch removal of nitrogen operation parameter nitrification denitrification |
