摘要
以大庆市万宝湖为研究区域,应用MIKE21软件,建立万宝湖水动力和水质二维耦合模型,以实测资料为依据,进行模型参数的率定和验证。结合模拟结果,分析了万宝湖的水动力条件变化特征及其对于水环境中各种污染物迁移转化机制的影响。结果表明,万宝湖各主要污染物在靠近湖岸和排口附近浓度较大,并由湖岸向湖心呈梯度递减,形成岸边污染带,各污染物在不同的排口浓度分布具有差异性。最后,针对万宝湖的污染状况和污染物分布特点提出了相应的治理建议。
The two-dimensional hydrodynamic and water quality coupling model was established using MIKE21,which was applied to Wanbao Lake,Daqing City.The parameters in the model were calibrated and verified based on the measured data.Furthermore,the hydrodynamic characteristics of the Wanbao Lake and its influence on the migration and transformation of various pollutants in the water environment were analyzed combining with the simulation results.The research indicated that：the lake shore was the main pollution zone where the concentrations of main pollutants were high;the concentrations decreased gradually from the lake shore to the lake center in Wanbao Lake;the pollutant concentrations changed with a wide range in different sewage outfalls.At last,according to pollutant distribution characteristics of Wanbao Lake,suggestions for the treatment of pollution situation were put forward.
