水电站建设对水环境容量的影响研究

水电站建设影响河道水环境容量。为研究水电站建设对水环境容量的影响,本文以汉阳水电站为例,采用一维水环境容量计算方法,计算相应河段建库前后水环境容量,并分析了降解系数的取值对水环境容量的影响。结果表明建库后水流流速减缓,污染物降解时间增加,从而增大水环境容量;而水流流速减缓,降解系数减小,从而减小水环境容量。在二者共同作用下,汉阳水电站建库前后水环境容量变化不大。

Study on the Impact of Hydropower Station Construction on Water Environmental Capacity

Hydropower station construction affects the water environmental capacity of the watercourse.In this paper onedimension model is used to estimate the water environmental capacities before and after construction of Hanyang hydropower station.The effect of degradation coefficient value on the water environmental capacity is analyzed.The result shows that the decreased flow speed resulted from the construction of reservoir leads to increasing the time of pollutants degradation and consequently decreasing the wa...
