数值模拟在合肥市四里河水环境治理中的应用

Application of Numerical Simulation to Water Environment Treatment of the Sili River in Hefei

数值模拟是用数学的方法描述流体及污染物质的物理、化学、生物化学等方面的变化。建立水质模型对于预测水环境质量和制定水环境治理对策措施具有十分重要的意义,是地表水环境污染治理的有效手段。在河道水环境现状分析、污染源调查的基础上,建立1D水质模型,模拟截污纳管措施下的水环境状况,从而为合肥市四里河水环境综合治理提供决策依据。

Numerical simulation is a mathematical method to describe the physical,chemical&biochemical changes of fluids&pollutants.The establishment of water quality model is of great significance for the prediction of water environment quality and the formulation of water environment control measures,and it is an effective means of surface water environmental pollution control.Based on the analysis of the current situation of river water environment and the investigation of pollution sources,a 1D water quality model is established to simulate the water environment under the measures of sewage interception and receiving,so as to provide the decision-making basis for the comprehensive treatment of the Sili River environment in Hefei.
