山东省沂源县天然矿泉水成因及水质评价研究

Research on the origin and water quality evaluation of natural mineral water in Yiyuan county,Shandong province

山东省具有丰富的天然矿泉水资源,其中沂源县被誉为“矿泉水之乡”。将位于沂源县南鲁山镇璞邱村的YY17号井作为典型矿泉水水源井,对该YY17号饮用天然矿泉水井进行调查研究,进而分析该区域矿泉水水源地地质构造条件、成因和水化学特征,在此基础上查明YY17井矿泉水资源的赋存条件、富集规律和水质等级。结果表明:研究区主要分布新太古代变质岩及寒武纪、奥陶纪碳酸盐岩,断裂构造发育,为优质锶型矿泉水的赋存提供了有利条件;在淋滤作用和溶解作用下,大量的锶溶解入水,造成了地下水中锶元素的富集,形成锶型饮用天然矿泉水,水质符合《饮用天然矿泉水》国家标准中的锶型矿泉水要求,属于优质的锶型天然矿泉水。针对我国矿泉水行业发展的广阔前景,沂源县应加强地下水水源地监管保护,科学开发利用好区域的优质矿泉水资源,为区域经济社会发展提供支撑。

Shandong Province is rich in natural mineral water resources,among whichYiyuan County is known as the“Hometown of Mineral Water”.Taking Well YY17 in Puqiu Village,Nanlushan Town,Yiyuan Country as a typical mineral water source well,investigate and study the YY17 drinking natural mineral water well,and then analyze the geological struc⁃ture conditions,genesis and water chemistry of the mineral water source in this area Based on the characteristics,find out the occurrence conditions,enrichment rules and water quality grades of the mineral water resources in Well YY17.The results show that the study area is mainly distributed with Neoarchean metamorphic rocks and Cambrian and Ordovician carbonate rocks,with developed fault structures,which provide favorable conditions for the occurrence of high-quality strontium-type mineral water;in leaching and dissolution A large amount of strontium is dissolved into the water,resulting in the enrichment of strontium in groundwater,forming strontium-type drinking natural mineral water.The water quality meets the requirements of strontium-type mineral water in the national standard of“drinking natural mineral water”,and belongs to high-quality strontium-type natural mineral water.In view of the broad prospects for the development of China's mineral water industry,Yiyuan County should strengthen the supervision and protection of groundwater sources,scientifically develop and utilize re⁃gional high-quality mineral water resources,and provide support for regional economic and social development.
