白山市南山生活垃圾填埋场对地下水环境的影响分析

Impact of Nanshan municipal solid waste landfill on groundwater environment in Baishan City

本文阐述了白山市南山垃圾填埋场的项目区概况,污染现状,地层岩性及水文地质条件。通过实施补充勘察手段,查明了工作区污染物分布及地下水质量现状,采用建立指数函数模型、一维稳定流弥散方程等计算方法,以含量相对较高的化学需氧量做为代表因子,预测分析生活垃圾填埋场近20年来对地下水的污染情况及影响范围。

In this paper,the general situation of the project area,pollution status,stratum lithology and hydrogeological conditions of Nanshan landfill site in Baishan City were described.By means of supplementary survey,the distribution of pollutants and the current situation of groundwater quality in the working area were found out.By establishing exponential function model,one-dimensional steady flow dispersion equation and other calculation methods,the relatively high chemical oxygen demand was taken as the representative factor to predict and analyze the pollution situation and influence range of groundwater in domestic waste landfill site in recent 20 years.
