摘要
为水污染治理提供准确的参考依据,提出水环境污染水平及污染源分布数值模拟分析。分别从气候、水文地形等方面探究目标区域的基本信息,根据二维水动力方程建立水环境模型,通过输移物浓度等参数描述水污染变化过程;估算不同污染源负荷量,计算溶解氧、总氮、总磷等主要污染指标含量,实现污染水平模拟;分类污染源,利用因子分析法识别污染源,模拟污染源的具体分布情况。研究表明:该方法模拟精度高,Ens和R2最高值达到了0.97和0.99,并且模拟结果与实际监测情况相符,能够为水污染科学治理提供充足的依据。
To provide accurate reference basis for water pollution control,the numerical simulation analysis of water environmental pollution level and pollution source distribution is proposed.The basic information of the target region was explored from the aspects of climate and hydrological topography,and the water environment model was established according to the two-dimensional hydrodynamic equation.The water pollution change process was described by parameters such as the concentration of transported matter.The load of different pollution sources was estimated.The contents of dissolved oxygen,total nitrogen,total phosphorus and other major pollution indicators were calculated to simulate the pollution level.The study classified pollution sources,identified pollution sources by factor analysis,and simulated the specific distribution of pollution sources.The results show that the simulation accuracy of this method is high,with the highest values of and reaching 0.97 and 0.99.The simulation results are consistent with the actual monitoring situation,which can provide sufficient basis for the scientific control of water pollution.
