Effects of Environmental Factors of Overlying Water on the Release of Nitrogen and Phosphorus from Sediment of Coastal Reservoir

  • 摘要: 为了解我国滨海水库富营养化过程,以北大港水库沉积物为研究对象,通过室内模拟试验,考察上覆水环境因子〔扰动、ρ(Cl-)、pH、温度、ρ(DO)〕对滨海水库沉积物氮、磷释放的影响.结果表明:①扰动促进氮、磷的释放,ρ(NH3-N)、ρ(NO3--N)、ρ(TN)和ρ(TP)增加了54.4%~230.8%,扰动对滨海水库沉积物TN、TP释放通量的促进作用比淡水沉积物强;②ρ(Cl-)升高促进氮、磷释放,ρ(Cl-)越高,促进效果越强,ρ(Cl-)为1 000和5 000 mg/L时,ρ(NH3-N)、ρ(NO3--N)、ρ(TN)和ρ(TP)分别增加了4.2%、3.2%、35.0%、11.9%和8.4%、4.8%、44.7%、23.8%;③与pH为7.0时相比,pH为8.5和10.0时,ρ(TP)增加了21.3%~42.6%,ρ(NH3-N)降低了14.9%~18.6%,ρ(NO3--N)和ρ(TN)基本没有变化,但NO3--N释放通量增加了5.2%~10.3%,TN的释放通量降低了7.1%~21.5%;④温度升高促进了NH3-N、TN和TP释放,抑制了NO3--N释放,滨海水库沉积物中较高的盐度减弱了温度对TP释放的促进作用,25 ℃时,ρ(NH3-N)、ρ(TN)和ρ(TP)比5 ℃时增加了37.3%~71.0%,ρ(NO3--N)降低了34.0%;⑤好氧条件抑制了NH3-N、TN和TP释放,促进了NO3--N释放,好氧条件下ρ(NH3-N)、ρ(TN)和ρ(TP)降低了54.2%~85.6%,ρ(NO3--N)增加了20.5%.研究显示,上覆水环境因子会影响滨海水库沉积物氮、磷释放,其中以扰动、温度和ρ(DO)影响较大.
