Simulation of reducing release of internal source in lake by geocell

  • 摘要: 湖泊富营养化与内源释放有密切的关系,降低湖泊因水动力作用引起的底泥再悬浮可大幅度减少湖泊内源污染物的释放。使用数值方法模拟水流在遇到阻碍后的流速变化,分析比较了不同规格的土工格室对湖泊流速的降低情况。结果表明:水流经过土工格室后,湖底的流速有较大程度下降;土工格室上方区域流速随格室高度增加而加快,土工格室后方底层区域流速大小随着土工格室高度的增高而降低,土工格室能将其后方大部分区域内的流速降低到“个别动”起动流速以下;增加土工格室长度对流速影响幅度有限。
    Abstract: Lake eutrophication has a close relationship with the release of internal source. Decreasing the lake sediment resuspension caused by hydrodynamic effect can reduce the release of its endogenous pollutants. A numerical method is proposed to simulate the variation of flow velocity when it meets obstacles, and the decrease of flow velocity is investigated by different sizes of geocell. The results show that the water velocity has more significant decline when it passes the geocell in the lake bottom. The numerical results show the flow velocity above the geocell increases that behind the geocell decreases with the the height of geocell. The flow velocity in most areas behind the geocell can be reduced to “little action” or less. There are very limited effects for the flow velocity by increasing the length of geocell.
