摘　　要：通过对某化工园区开展物探测量、钻探、水文地质试验、测井、水质分析等工作得到相关水文地质参数,应用Visual Modflow软件建立相应的数学模型,并通过MT3DMS溶质运移模块对特征污染物在连续源强、瞬态源强下及储罐火灾爆炸风险工况下化工原料渗漏及污水泄露进行污染物运移规律的模拟和预测。结果表明,在连续源强、瞬态源强下,起初一年间污染物浓度会因污染源渗漏或泄露而增加,但随时间的增加浓度会随地下水的流动扩散,且逐渐被稀释,这为地下水环境影响预测提供了可靠依据。The related hydrogeological parameters were obtained through the exploration,drilling,hydro geological tests,logging and water quality analysis of a chemical industrial park.Visual mod flow was used to establish mathematical model.Based on the MT3DMS solute transport module,the pollutant transport law of characteristic pollutants’ chemical raw material leakage and sewage leakage were simulated and predicted under the conditions of continuous,transient source strength and tank fire and explosion risk.It is concluded that under the conditions of continuous and transient source strength,the concentration of pollutants may increase due to leakage of pollution sources in the first year.But the concentration will be gradually diluted with time increase due to the flow of groundwater.Thus,it provides reliable basis for prediction of groundwater environment impact.
