| 摘 要： | 为了研究底泥氨氮释放对汤河水库水质的影响,采用室内模拟的方法,研究汤河水库底泥在不同浓度、温度、pH值、扰动、溶解氧条件下氨氮的释放特征.试验结果表明:不同浓度的上覆水对于底泥氨氮的释放量影响不大;底泥氨氮的释放量随温度升高而增加;上覆水pH=8时有利于底泥氨氮的释放;扰动有利于底泥中氨氮的释放;贫氧条件有利于底泥氨氮的释放.

| Abstract: | In order to study the influence of sediment releasing ammonia nitrogen on water quality of Tanghe Reservoir, the ammonia nitrogen release characteristics of Tanghe Reservoir＇s sediment is researched under the different temperature, pH, turbidity degree, and dissolved oxygen concentration. The results show that it is concluded that different concentrations of the overlying water has little effect on the release of sediment ammonia, which increases with the increasing temperature. And the overlying water with pH = 8, the dis- turbance, and oxygen-poor conditions are conducive to the release of sediment ammonia. |
