基于里下河河网水文水动力模型,模拟了盐城蟒蛇河突发性水污染事故中不同调水方案下的污染物运移过程。定量模拟了突发性水污染事故发生后,不同引排水流量及其不同供水口门对污染物下移的影响。结果表明新洋港排水流量对污染团在河网中迁移的影响为主要控制因素。模拟结果可为盐城蟒蛇河水源地突发性水污染事故的处理提供理论依据。
Hydrological and hydrodynamic models in Li-xia River is used to simulate the mobility of pollutants under different water transfer plans in sudden water pollution accidents .This model can quantitatively predict the time of the pollutant movement under different inflow/outflow and different diversion gates .The result shows that the outflow in Xinyang Port is the main influence factor for pollutant movement . The result can provide an important theoretical basis for the treatment of unexpected water pollution emergency .
