摘　　要：某污水厂对奥贝尔氧化沟工艺在运行中出现的泡沫问题、污泥上浮及污泥膨胀等问题进行分析,并进行了工艺改进和运行模式调整,通过比较工艺改进前后污泥浓度、溶解氧浓度及主要水质指标,讨论改进后的奥贝尔氧化沟工艺处理效果。The foam problem, sludge floatation and sludge bulking in Orbal oxidation ditch process were analyzed in a sewage treatment plant, and the process improvement and operation mode adjustment were carried out. By compar. ing the sludge concentration, dissolved oxygen concentration and main water quality indexes before and after the pro. cess improvement, the treatment effect of the improved Orbal oxidation ditch process was discussed.
