Dissolved oxygen transfer in an aeration pond was studied by numerical method in this paper. 2d water pond current induced by water-wheel aerators and oxygen transfer process was simulated by finite volume method. In order to verify the relationships between current and dissolved oxygen transfer, we set 4 layout styles with 4 aerators in a water pond. It is proved that different layout styles induce different flow structures and dissolved oxygen distribution. Traditional layout (style a) is not the best way for oxygen transfer, and other styles (style b, c &d) are all superior to the traditional layout. But water flow structures are not the same results. Water circulation performance is style a, c, b, d in sequence. Style c (flow to corners along pond wall) is the best way by comprehensive consideration of both water circulation performances and dissolved oxygen distribution.
