中文摘要:
      贵州省饮用天然矿泉水资源非常丰富,且水质优良,本文对贵州省岩溶地区饮用天然矿泉水进行了系统的水样采集、水质化验等工作。检测结果显示,贵州省岩溶区饮用天然矿泉水pH值7081,为中性水;溶解性总固体(TDS)含量介于1606492510 mg/L之间,平均含量为36970 mg/L,属淡水;总硬度(以CaCO3计)13687406 mg/L,平均硬度为2930 mg/L,属微硬-硬水;有益元素锶含量介于011691 mg/L之间,平均含量为128 mg/L,总体上,贵州省饮用天然矿泉水属中性微硬-硬富锶型淡水。Piper三线图显示其水化学类型以HCO3--Ca2+(Mg2+)为主。基于前人研究成果,并结合多种地球化学图解分析,旨在剖析贵州省饮用天然矿泉水水化学特征,探讨其宏量组分来源。贵州省饮用天然矿泉水Gibbs图解显示,其水化学组分主要来源于岩石风化淋滤作用,部分受大气降雨影响较明显;Mg/Na-Ca/Na图解投点均落于碳酸盐岩和硅酸盐岩之间,且明显偏向于碳酸盐岩,指示其主要受控于碳酸盐岩的溶滤作用;HCO3--(Mg2+/Ca2+)图解投点主要集中在方解石和白云石过渡区域,显示其主要来源于方解石的溶解,白云石溶解亦有一定贡献。通过宏量组分来源相关分析,对贵州省岩溶地区饮用天然矿泉水成因规律的认识有一定指导意义。
英文摘要:
      The natural mineral water resources is rich in Guizhou province, and the quality of the water is excellent. In this paper, the drinking of natural mineral water in karst areas of Guizhou province has been collected and tested systematically. The test results show that its pH value of potable natural mineral water in karst areas of Guizhou province were ranges from 7.0 to 8.1, which was neutral water. Total Dissolved Solids (TDS) content ranged from 160.64mg/L to 925.10 mg/L, with an average content of 369.70 mg/L. The total hardness (calculated by CaCO3) is 136.8 mg/L~740.6 mg/L, with an average hardness of 293.0 mg/L. The strontium content of beneficial elements is between 0.11 mg/L and 6.91 mg/L, with an average content of 1.28 mg/L. In general, natural mineral water for drinking in guizhou province is a kind of neutral and slightly hard strontium-rich fresh water. Piper diagram indicate that the hydrochemical type are mainly HCO3--Ca2+(Mg2+). Based on the previous research results, combined with a variety of geochemical graphic analysis, this paper aims to analyze the characteristics of the hydrochemical composition of potable natural mineral water in Guizhou province, and to explore the source of its macro components. The Gibbs diagram of potable natural mineral water in Guizhou province shows that the hydrochemical components are mainly derived from rock weathering and leaching, and some of them are affected by atmospheric rainfall obviously. The Mg/Na-Ca/Na diagrams show that the point are all between carbonate rocks and silicate rocks, and they are obviously inclined to carbonate rocks, indicating that they are mainly controlled by the hydrolithogenesis of carbonate rocks. The projection point of HCO3-- (Mg2+/Ca2+) diagram is mainly concentrated in the transition region between calcite and dolomite, indicating that it mainly comes from the dissolution of calcite, and the dolomite dissolution also contributes to a certain extent. Through the analysis of macroscopic component source, it has a guiding significance to reveal the genetic law of potable natural mineral water in karst area of Guizhou province.
