长白山地区安图县矿泉水水化学成因及水质健康功能评价

Hydrochemical Origin and Water Quality Health Function Evaluation of Mineral Water in Antu County of Changbai Mountain Area

针对长白山地区安图县矿泉水资源开发利用程度的不断增加,为进一步提高矿泉水资源价值和功能,利用该区矿泉水化学监测数据,采用地统计与水化学分析等多种方法开展了矿泉水水化学特征及成因研究,构建水质健康功能评价指标体系。结果表明:研究区矿泉水以单一偏硅酸型及CO_(2)复合偏硅酸型为主,复合型矿泉的TDS、总碱度、总硬度及CO_(2)含量比单一型矿泉高出1~2个数量级,偏硅酸含量与其他组分相比具有不同的空间分布特征,岩石风化作用是偏硅酸型矿泉水形成的主要原因、深部热水沿裂隙上升与浅层地下水混合是复合型矿泉形成的主要原因。区域广泛分布弱碱性低硬度的偏硅酸型矿泉,各指标含量符合矿泉水质量标准且具有良好的口感。

In this paper,based on the monitoring data of mineral water chemistry in Changbai Mountain Area,geostatistics and hydrochemical analysis method are used to study the chemical characteristics and causes of mineral water,and the evaluation index system of water quality health function is established.The results show that:the mineral water in the study area is mainly composed of single metasilicic type and CO_(2) compound metasilicic type.The TDS,total alkalinity,total hardness and CO_(2) content of the composite mineral spring are 1~2 orders of magnitude higher than that of the single type mineral spring.The metasilicic content has different spatial distribution characteristics compared with other components.Weathering of rocks is the main reason for the formation of metasilicic mineral water and the main reason for the formation of the composite mineral spring is that the deep hot water rises along the fracture and mixes with the shallow groundwater.Weak alkaline and low hardness metasilicic type mineral spring is widely distributed in the region.The content of each index meets the quality standard of mineral water and tastes good.
