摘要
采用一维水动力数学模型和水质数学模型,对梯级电站建设前后的CJ江干、支流的水质变化进行研究,预测CJ江2020年5个梯级电站建设后干流水质主要参数的变化情况。结果表明,各梯级电站水库蓄水后各坝址处平均DO质量浓度将较建库前略有下降,BOD5和NH3-N的质量浓度呈下降趋势,TP质量浓度变化较小。
In this study, a one-dimensional hydrodynamic numerical model and a one-dimensional water quahty mathematical model were established to study the variation of flow in branches and the main stream of the CJ River before and after the construction of cascade hydropower stations. The variations of water quality indicators of the main stream of the CJ River after five cascade hydropower stations are constructed in 2020 were predicted. The results show that the average DO concentration at the dam site will be lower after reservoir storage than they are before the construction of the reservoir at the cascade hydropower stations, the concentrations of BOD5 and NH3-N will have a decreasing trend, and the concentration of TP will not change significantly.
