摘要
城市经济聚集区生产与生活行为较为密集,水环境污染负荷较大,再加之水环境的动态性、不确定性,致使水环境污染控制难度较大。文章深入分析城市经济聚集区水环境污染负荷情况,通过水流模拟数学模型建立、研究区域空间离散与时间离散处理、初始条件与边界条件,构建水环境污染负荷模拟基础模型,探究水环境污染物质运移规律,应用模拟软件,设置相关参数,即可实现水环境污染负荷的模拟。实验数据显示:应用提出方法获得的重金属、氨氮污染物模拟浓度数值与实际浓度数值几乎保持一致,充分证实了该方法具有较好的水环境污染负荷模拟效果。
The production and living behaviors in urban economic agglomeration areas are relatively intensive,and the water environment pollution load is large.Coupled with the dynamic and uncertainty of the water environment,it is difficult to control the water environment pollution.In this paper,the water environment pollution load in urban economic agglomeration areas is deeply analyzed.Through the establishment of mathematical model of water flow simulation,the regional spatial and temporal discrete processing,initial conditions and boundary conditions are studied,the basic model of water environment pollution load simulation is constructed,the migration law of water environment pollutants is explored,and the simulation of water environment pollution load can be realized by applying simulation software and setting relevant parameters.The experimental data show that the simulated concentration values of heavy metals and ammonia nitrogen pollutants obtained by the proposed method are almost consistent with the actual concentration values,which fully confirms that the method has a good simulation effect of water environment pollution load.
