密云水库沉积物中磷释放的环境因子影响实验

Study on Environmental Factors Controlling the Release of Phosphorus in Miyun Reservoir Sediments

  • 摘要: 为了探讨密云水库沉积物中磷的释放条件,在实验室模拟了改变溶解氧浓度、调节pH、温度等因素对磷释放的影响实验。结果表明:厌氧条件下沉积物中释放磷的总量是好氧条件下的10倍;上覆水pH值升高有利于沉积物中磷的释放;温度升高,沉积物中磷的释放强度随之增大。同时说明了水库内源性磷对水库水质存在着潜在威胁,为研究水库内源性磷对水质的影响和对水库富营养化趋势的预测提供了可靠的依据。

     

    Abstract: The release of phosphorus from the Miyun Reservoir sediments was simulated under the different DO,pH and temperature conditions in the lab. The results showed that in anaerobic condition, the release rate of phosphorus is 10 times as higher as in aerobi
