摘要: 在NH₄-N水环境行为研究的基础上建立洛河NH₄-N水环境模型,并将其应用于计算NH₄-N水环境容量及削减量。研究表明,洛河高崖寨及白马寺国控断面NH₄-N浓度超标,主要受河流流量和温度影响。在超标断面的基础上,研究区域被划分为两个控制单元,并依据一级反应动力学建立洛河NH₄-N降解模型。不同控制单元采用两个降解系数:0.81 d^-1和0.34 d^-1,并在模型验证过程中表现出较高的准确性。利用所建立的NH₄-N水环境模型计算出两个控制单元NH₄-N环境容量分别为0.367和2.13 t/d,削减量为0.264和1.45 t/d。

Abstract: A NH₄-N water environmental model of Luo River was built up on the basis of the behaviour study of NH₄-N in water environment and then applied in the calculation functions submitted to the NH₄-N water environmental and reduction capacities of the designated control units. The results showed that NH₄-N concentrations at the national control sections of Gaoyazhai and Baima Temple of Luo River exceeded the standard limit, mainly affected by the water flow and temperature. Then, the study regions were divided into two control units, and the NH₄-N degradation model of Luo River was constructed according to the first-order reaction kinetics. Two degradation coefficients, 0.81/d and 0.34/d, were adopted in different control units and higher accuracy was showed in the model verification process. By use of the constructed NH₄-N water environmental model, NH₄-N environmental capacities of the two control units were calculated as 0.367 and 2.13 t/d, and the reduction capacities were 0.264 and 1.45 t/d respectively.
