吉林省抚松县矿泉水形成机理及过程模拟

Mineral Water Formation Mechanism and Process Modeling in Fusong County

根据在抚松县收集的水样以及测定的数据,做出Piper三线图以及分析了水化学特征。对水中氘氧同位素进行检测和含量分析,得知补给来源为大气降水;并根据氘的高程效应计算出补给高程在1 000~1 500 m之间,补给区域为自然保护区内、露水河镇的北部与东部、东岗镇及漫江镇的西南侧;利用放射性同位素氚计算了地下水年龄为30~50 a;并定性分析为现代水。运用Phreeqc软件中反向水文地球化学模拟模块对研究区三条路径上的水岩相互作用做了模拟,得知钾钙离子主要来源于钾、钙长石,镁离子主要来源于白云石,钠离子主要来源于岩盐和阳离子交换反应,锶来源于菱锶矿、钾长石、钙长石当中,偏硅酸来源于长石和伊利石。对于矿泉水的形成,前人一般从地质构造和水动力条件方面分析;且对抚松当地的矿泉水研究甚少。从质到量及时间空间的角度上系统地分析了抚松当地矿泉水的形成机理。

Based on the water samples measurement data in Fusong County, made Pij^er diagram, and analyzedthe water chemical characteristics, according to the content of .D and . 18 0 , learned that recharge sources is precipitation and according to the 8D elevation efects calculated the recharge elevation is between 1 000 - 1 500 m, recharge area are natural protection zones, nortiieast Lushui river town, and southwest of Donggang town and Manjiang town. Radioactive isotopes tritium was used to calculate the groundwater age that is 30 ~ 50 a , andqualitatively named it modem water. Using Phreeqc software reverse modeling in the three paths of water rockinteraction simulation, learned that Km ＆Ca2m mainly comes from ortiioclase and anortiiite, Mg2m mainly comes fromdolomite, Na m mainly comes from halite and cation exchange reaction, Sr2 m comes from strontianite, ortiioclase and anorthite,H SO3 comes from feldspar and illite. Previous research from the point of geological structure and hydrodynamic conditions, and the study on Fusong mineral water is very r r e . IFusong county local mineral water was analyzed, from the asjcect of quantity to quality.time and space.
