Calculation and Analysis the Water Environment Capacity for Taizi River Basin

According to the one-dimensional and two-dimensional water quality model, establish the model of water environmental capacity. Based on the comprehensive analysis of the Taizi River´s water quality conditions, pollution sources and the characteristics of pollutants, selected one-dimensional model to calculate the water environmental capacity of the Taizi River. Basis of the river function zoning case, combined the various water quality cross section of the Taizi River basin and the monitoring data from the Tang Mazhai hydrological stations, calculated the water environmental capacity on the Taizi River´s main pollutant COD in different guaranteed rate (90%, 75%, 50%) cases, analyze the results and put forward measures to further improve the water environment.
