摘要
上海老港垃圾填埋场地处海滨,其地下水系统受到垃圾渗沥液和海水的双重影响。为评价由渗沥液所导致的地下水污染,提出了新的评价对照值产生方法,以屏蔽海水的影响。评价结果表明:填埋场地下水系统明显受到垃圾渗沥液污染,主要污染成分是NH3-N、CODMn、重金属Pb和Cd;不同污染成分在地下水系统的空间分布存在显著差异;渗沥液对地下水的总体污染程度正在加重。
Shanghai Laogang Waste Landfill Site is located at the seashore zone, and its groundwater system is subject to the combined influence by the leachate and seawater. In order to evaluate the groundwater pollution caused by the leachate, a novel method for generating contrast values was developed, which can mask the effect of seawater. The evaluation results indicated that the groundwater system was evidently contaminated by the leachate, and the pollutants mainly included NH3-N, CODMn, Pb and Cd. The spacial distribution of different pollutants in groundwater system is diverse. The total pollution level of groundwater caused by the leachate is increasing.
