摘要
介绍了奥伯尔氧化沟流程及长岭炼油化工总厂奥帕尔氧化沟的溶解氧控制现状，分析了影响溶解氧控制的相关因素，并针对该厂奥伯尔氧化沟的施工、设计原因造成的曝气设备充氧能力降低及各沟充氧能力不匹配等问题进行了讨论，同时对存在的问题提出了改进意见。
The process of Orbal oxidation ditch and the situation of the dissolved oxygen control of the Orbal oxi- dation ditch in Changling General Works of Petroleum and Petrochemicals were introduced.Relative factors affecting dissolved oxygen control were analyzed. Discussions were given to foe problems such as oxygenation ability decrease of aerator and mismatching of oxgenating ability of each oxidation ditch caused by construction and design. Sugges- tions for improvement were also proposed.
