洛阳市某垃圾场渗滤液对地下水的污染预测

Assessment of Groundwater Pollution by a Certain Landfill Leachate in Luoyang City

垃圾填埋场的主要危害在于垃圾淋滤液对地下水的污染。本文以洛阳市某垃圾场为例,运用MODFLOW和MT3D软件模拟分析在未来垃圾渗滤液对地下水的污染程度。结果证明,虽然该垃圾场做过卫生防护,但仍然会对地下水造成一定的污染,污染范围随着时间的推移而逐渐增大,因此必须采取必要的防护措施。

Leachate is the main medium for the transport of contaminants from the landfill to groundwater.This report took a landfill in Luoyang city as an example,and used the modular 3D finite difference groundwater flow model（Modflow）and Modular 3D Finite Difference Mass Transport Model（MT3D）software to simulate groundwater flow and leachate transport.The results indicated that the groundwater pollution by leachate worsening day by day although the prevention measures has been done.
