Abstract: Based on groundwater, surface water quality standards, water environmental quality evaluation criteria suitable for landfill was established and the water quality index method was used for water quality evaluation of the landfill area through investigating the water environment and sampling in the study area. By analyzing the sub-division of the basin, the water quality features, the hydrogen and oxygen stability isotope characteristics, combined with the geological environment, three ways to water pollution caused by landfill were determined. By comparing massive components, micro components and organic micro components (polycyclic aromatic hydrocarbons, phthalate esters, BTEX), according to the degree of water quality higher thanthe background value for the leachate and the contaminated water points, alandfill groundwater pollutionindex systemwas tried to be established, as indicative choices for landfill groundwater pollution source identification and water pollution assessment.

Key words: landfill, groundwater, Likeng landfill, water environmental effects

摘要： 通过对研究区的水质调查与采样分析, 基于地下水、地表水等水质标准, 尝试确定了适宜于垃圾填埋场区的水环境质量评价标准, 采用水质指数法进行了填埋场区水质评价; 基于子流域划分、水质超标特征、氢氧稳定同位素特征, 结合地质环境研究, 确定了填埋场水污染的3 种途径; 通过背景水点与渗滤液、污染水点的大量、微量与有机微量(多环芳烃、邻苯二甲酸酯、苯系物3类)组分对比分析, 依据污染水点和渗滤液超过背景值的程度选择代表性指标, 尝试构建填埋场地下水环境污染指标体系, 为填埋场地下水环境污染来源识别与水污染评价指标选择提供依据。
