摘要
含水层中氮污染已经是相当普遍的问题。本文分析了含水层中水流运动、对流—弥散作用、物理化学吸附和生物化学反应等对污染物运移的影响,特别是阐述了含水层中NO-3、NO-4三种形式之间的转化关系,在此基础上,探讨了这些物理、化学和生物作用导致2、NH+的物质转化过程定量描述的数学模式。
Nitrogen pollution is quite an ordinary problem in aquifer The effect on pollutant movement resulted from water-current in water-bearing stratum,convection-dispersion process,physicochemical adsorption and biochemical reaction are analyzed,especially the relation of NO - 3,NO - 2 and NH + 4 in water-bearing stratum is expound in this paper On the basis of it,we study a mathematical model leading to material transformation in physics,chemistry and biological process
