摘要
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。
This paper takes a municipal solid waste landfill in Anhui Province as research object. The quality of four groundwater monitoring wells was tested and evaluated. Monitoring targets are total hardness,ammonia nitrogen,Pb,As,Hg,and other routine groundwater monitoring programs. The results show that most of the heavy metals in the surrounding groundwater are not detected in the initial landfill stage of MSW landfill. But the content of total hardness,total dissolved solids and inorganic salts are higher. 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.
