河道纳污模型研究与应用

Study of capacity calculation model and the parameter for rivers

根据河流水质模型理论,在一定水文设计条件和水质目标前提下,分析不同计算方法选取对河流纳污能力计算结果的影响,探讨不同上游本底浓度、不同污染源排放方式、不同控制断面设定的河流纳污能力计算方法的结果差异性,通过案例分析,与河流实测水质吻合良好,可为河流纳污能力研究与水环境保护提供技术支持.

According to the theory of river water quality model,this paper,under the precondition of certain hydrological design condition and water quality target,makes an analysis of different parameters selection of river pollutant carrying capacity calculation results,discusses the influence of different background concentrations upstream and sources discharge way,and different control section setting of river,the result difference of carrying capacity calculation method.Through the case analysis and consistency with the measured water quality,river to river,it provides a technical support for research and protection of water environment carrying capacity.
