摘要:
针对突发水污染事件所带来的潜在风险,基于Delft3D软件建立了长江澄通河段的二维水动力-水质模型,研究了苯酚泄漏事件对澄通河段狼山和长青沙2个主要水源地的影响。在模型率定和验证的基础上,设计了4种不同径潮组合下苯酚泄漏事件的计算工况。结果表明:上游径流的增强将有助于污染物更快流往下游,扩大了污染扩散范围使下游受影响范围也相应加大; 潮流的往复运动能增强污染团稀释效果,但也会增加水质超标影响时间。对比研究发现,枯季大潮期间发生的突发性水污染事件对澄通河段2个主要水源地影响最大。
Abstract:
Aiming at the potential risks caused by sudden water pollution events, a two-dimensional hydrodynamic and water quality model of Chengtong Section of the Yangtze river was established based on Delft3D software, and the effects of phenol leakage on the two main water sources in Chengtong Section of Wolf mountain and Changqingsha were studied.On the basis of model calibration and verification, the calculation conditions of phenol leakage events under four different runoff and tide combinations were designed.The results showed that the enhancement of the upstream runoff would help the pollutant flow to the downstream more quickly and expanded the pollution diffusion area and the affected area of the downstream.The back and forth movement of tidal current could enhance the dilution effect of pollution group, but also increase the influence time of water quality exceeding the standard.The comparative study found that the sudden water pollution incidents during the dry season have the greatest impact on the two major water sources in the Chengtong Section.
