摘要
摘要:影响珠江三角洲水资源配置工程取水口周边水环境风险的要素较多，利用EFDC模型，分析模拟取水口主要水质要素运动规律，以有效应对突发水污染事件。基于EFDC模型的水动力模型，构建了取水口所在河道的NH₃-N模型与溢油模型。根据取水口周围存在的风险源，设置了6种突发水污染事件情景，并采用NH₃-N模型与溢油模型对突发水污染事件情景进行了模拟。模拟结果表明，取水口上游西江干流右岸突发水污染事件不会对取水口造成影响，但左岸突发水污染事件会造成重大影响。

Abstract:Many environmental risk factors exist around the water intake of Zhujiang Delta Water Resources Allocation Engineering. To effectively respond to sudden incidents of water pollution, EFDC model was used to simulate and analyze movement of main water quality elements of water intake. Hydrodynamic model of EFDC, NH₃-N model and oil spill model were constructed. Six incident scenarios of sudden water pollution were set up according to risk source around the water intake, simulated by NH₃-N model and oil spill model. Simulation revealed that sudden water environment incidents on the right bank of West River upstream of the water intake will not affect water intake, but sudden water environment incident on the left bank will have a major impact on water intake.
