摘要
为某中等生活垃圾填埋场对地下水的影响,通过对该填埋场6口监测井地下水样品的采集与测试,运用单因子评价法和综合评价法对地下水质量进行评价,结果表明:生活垃圾填埋场及周边地下水呈弱碱性,阳离子主要为Ca^(2+)和Na^+,阴离子为HCO_3^-,NH_4^+-N、NO_2^--N、Mn、Fe超过地下水质量标准(GB/T14848-1993)Ⅲ类标准,说明填埋场对周边地下水存在影响,分析水质单因子评价和综合评价结果,认为填埋场对地下水可能有一定的影响,但没有波及到周边区域。应加强渗滤液调节池的管理和地下水监测,避免地下水造成污染。
In order to understand the impact to the groundwater of a secondary landfill, 6 monitoring wells groundwater samples were collected and tested, using single factor evaluation method and comprehensive evaluation method. The results showed that the landfill and the surrounding groundwater were weakly alkaline, cations were Ca2＋and Na＋, anion was HCO3-, the content of NH4＋-N, NO2--N, Mn and Fe was more than groundwater quality standard （ GB/ T14848- 1993 ） class Ⅲ standard, It was concluded from water quality analysis, single factor evaluation and comprehensive evaluation results showed that the landfill maybe had certain effect on groundwater, but did not spread to the surrounding areas. The management of leachate regulating pond and groundwater monitoring should be strengthened to avoid groundwater pollution.
