摘要
[目的]对临沂地区浅层地下水进行质量评价,确定地下水的污染现状。[方法]按每16 km2一个采样点的采样密度采集临沂地区的浅层地下水,共分析35项指标,选取其中影响水环境质量的17项指标进行评价。[结果]临沂地区浅层地下水较差和极差的比例达到了42.69%,影响浅层地下水质量的主要指标为Mn、Pb、Cl-、F-、NO2-、总硬度、溶解性总固体和高锰酸钾指数,多分布在居民聚居区、工矿企业及周边地区。[结论]该研究可为临沂地区地下水水质改良提供基本依据。
[ Objective] The research aimed to evaluate the quality of shallow ground water in Linyi City,and to determine the situation of ground water pollution. [ Method] Shallow ground water were collected every 16 km2 in Linyi, and 35 elements or indicators were tested. Among that, 17 elements or indicators influencing environment quality were chosen for evaluation in this research. [ Result] The results showed that,the worse and the worst ratio reached 42.69% about shallow ground water quality, the main indicators influencing shallow ground water quality were Mn, Pb, Cl- ,F ,NO2 - ,total hardness and total dissolved solids. They focused on the major areas,industrial and mining enterprises as well as their surroundings. [ Conclusion] This research could provide basic references for the improvement of ground water quality in Linyi City.
