| 摘 要： | 对长沙某污水处理厂的Carrousel氧化沟进行现场测试，获得不同截面的溶解氧和速度的数据，探讨了表曝机台数、沟深、沟的长宽比、进出水位置对溶解氧和速度的影响。初步掌握了该Carrousel氧化沟内溶解氧和速度的变化规律，认为通过调节倒伞形表面曝气机，可以在沟内不同区段创造好氧与缺氧的环境，为最终实现同步硝化反硝化的高效运行做准备。 |

| Abstract: | By experimenting in a wastewater treatment plant in Changsha, the distributions of dissolved oxygen & velocity at different locations in an oxidation ditch were obtained. The influences of aerators number, depth of oxidation ditch, as well as the ratio of oxidation ditch length to width were discussed. By analysis, it is found that the anaerobic region and aerobic region could be obtained simultaneously in one oxidation ditch. Then corresponding methods for the wastewater treatment plant are presented. All these provide evidence for the realization of simultaneous nitrification and denitrification in oxidation ditch in the future. |
