城市垃圾填埋场地下水污染的模拟与控制

Research on the Landfill Site Pollution Simulation and Control

在对北京市北天堂垃圾填埋场地进行野外调查的基础上 ,进行了室内土柱淋滤模拟实验和污染质数值模拟预报 ,提出了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 .通过对垃圾进行淋滤实验 ,分析了垃圾场中垃圾渗滤液污染物组分的变化特点 ,求得了数值模型所需的有关参数 .建立了北天堂垃圾场地下水污染的计算机模拟模型并进行了预报 ,取得了很好的效果 .最终提出了地下水污染的具体控制方案 。

Beitiantang landfill pollution in Beijing was investigated and studied in this paper. The laboratory column leaching tests and a numerical model for pollutants migration in the aquifer were done, some pollution control plans were proposed finally and their effects were simulated and discussed. Through the leaching test, the variation characteristics of the landfill leachate were analyzed, and some model parameters were estimated. A numerical model were built for the simulation of the underground migration o...
