- 摘要:
- 根据一维、二维水质模型，建立了水环境容量计算模型。在全面分析辽宁省某典型河流的水质状况、污染源及污染物特征的基础上，选取一维水环境容量模型进行计算。以河段功能分区情况为基础，结合该典型流域各断面水质及水文站的水文监测资料，对该河流的主要污染物COD在不同保证率（90%，50%，20%）情况下的水环境容量进行计算，全河段平水年水环境容量达2 520.71 t/d，并对结果进行了分析，在计算结果的基础上，提出了针对典型流域进一步改善和控制水环境的规划建议。
- Abstract:
- According to the one-dimensional and two-dimensional water quality model, the model of water environmental capacity was established. Under the comprehensive analysis of the water quality conditions, pollution sources of the typical watershed in Liaoning province and the characteristics of pollutants, one-dimensional model was selected to calculate the water environmental capacity of the typical watershed. Basis of the river function zoning case, combined the various water quality cross section of the typical watershed and the monitoring data from the hydrological stations, the water environmental capacity was calculated on the main pollutant COD in different guaranteed rate (90%, 50%, 20%), the water environmental capacity of the river in 50% is 2 520.71 t/d, and base on the results, the measures were put forward to further improve the water environment for the typical watershed.
