| 摘 要： | 在对开封市某典型垃圾场进行野外调查的基础上,应用Visual Modflow建立了该垃圾场污染场地的水流和溶质运移耦合模型并进行数值模拟预测,预测了20年后该污染场地垃圾渗滤液污染羽运移范围、途径及方式等特点。模拟了应用防渗墙和抽水井两种方式控制地下水污染的措施和方案,并利用计算机模型对污染控制的效果进行了模拟分析。模拟结果表明,模拟初期污染羽覆盖了3个抽水井,污染羽前缘距离村庄688 m。模拟20年后污染羽已经覆盖了7个抽水井,其中浓度超标井有3口,污染羽前缘距离村庄605 m。建议在加强污染物监测的同时协助开展其他的污染控制措施,进一步控制污染羽的扩散。

| Abstract: | On the basis of investigation of a typical landfill in Kaifeng city and then VisualModflow is used to establish a coupled model of water flow and solution transport and forecast the characteristic of transporting scope of contaminated leachate plume and means and methods of transposition in the contaminated site after 20 years.The results show that contaminated plume will cover three pumping wells and distance from the head of the plume to the village is 688m at the beginning of the simulation period,At 20 years after the simulation period,the plume will cover seven pumping wells,of which three wells exceeded the Standard concentration.Distance from the head of the plume to the village is 605m.Two ways to control groundwater pollution measures and programs are proposed such as walls and pumping wells.Computer models are used wo simulated the effects of pollution control.It suggests strengthening monitoring of pollutions and carrying out the other pollution control measures and further controlling the spread of the pollution plume. |
