Abstract:

The highly concentrated dissolved oxygen can keep aerobic acti vity for the active sludge flocculent particles in pure oxygen aerator system. T hus the removal of COD and sludge sedimentation are greatly improved. Even when the resistance of organism is high, the quality of outlet water is pretty good.

Key words: dissolved oxygen, activated sludge, wastewater treatment

摘要:

高溶解氧浓度,可使纯氧曝气系统中活性污泥的絮体颗粒保持好氧活性,因而使其COD去除率、污泥沉降性能都有很大提高,在抗高有机物冲击时,可保持良好的出水合格率。
