广州李坑垃圾填埋场水环境污染调查

Investigation on Water Environmental Pollution of Landfill Site Likang, Guangzhou

通过现场采样与历史资料统计,分析了广州市李坑垃圾填埋场垃圾渗滤液的水质特征,及其对地下水和地表水的影响强度及范围。结果表明,该场对环境产生影响的主要污染物是以NH_3-N、COD_(Cr)为代表的高浓度有机物。垃圾渗滤液对地下水的影响强度不大,对作为农业灌溉用水的地表水影响不超过2000m,对10km外的饮用水源不造成影响。

Based on the on-site sampling and statistical data, the characteristics of water quality of waste leachate and its impact on the underground and surface waters were analyzed. The result showed that the impacts of landfill site on water environmental pollution were mainly high concentrated organic matters represented by NH3-N and CODCr etc., rather on surface water than on underground water.
