中小城镇生活垃圾填埋场地下水环境质量评价研究

摘要

This paper takes a municipal solid waste landfill in Anhui Province as research object .The quality of four groundwa-ter monitoring wells was tested and evaluated.Monitoring targets are total hardness, ammonia nitrogen, Pb, As, Hg, and other rou-tine groundwater monitoring programs .The results show that most of the heavy metals in the surrounding groundwater are not detec-ted in the initial landfill stage of MSW landfill .But the content of total hardness , total dissolved solids and inorganic salts are high-er.Ammonia nitrogen, nitrate in some wells are higher permissible range of GB/T 14848-1993 III class standards.It indicates that the landfill field has some potential impacts on the surrounding groundwater .%以安徽省某县生活垃圾填埋场为研究对象，对该填埋场4口监测井的地下水进行监测分析和综合评价，监测目标为总硬度、氨氮、铅、砷、汞等地下水常规监测项目。监测结果表明：填埋初期的生活垃圾填埋场，周边地下水中重金属物质多数未检出，但总硬度、溶解性总固体和无机盐等物质含量较高，部分点位的氨氮、硝酸盐超过地下水质量标准（GB／T 14848－1993）Ⅲ类标准，可见填埋场对周边地下水存在影响。
