摘要
利用近十年的水化学资料,总结了河南省鲁山县五大温泉水质主要特征,分析了水质变化的总体趋势,对水质变化的具体原因进行了探讨。五大温泉具有富钠、高硫酸盐、高氟、高偏硅酸的水化学特征,为氟·硅复合型理疗热矿水。水质变化的总体趋势为,HCO_(3)^(-)含量呈明显的上升趋势,SO_(4)^(2-)、Na^(+)、F^(-)、H_(2)SiO_(3)含量总体上呈下降趋势,而H_(2)SiO_(3)尤为明显。造成这种变化的原因在于:由于十余年的持续大规模开发,开采量不断加大,热储压力逐渐降低,导致浅层凉水混入比例增加,从而引起水质发生上述变化。
Based on the hydrochemical data in recent ten years,the main characteristics of the water quality of the five thermal springs in Lushan County,Henan Province are summarized,the overall trend of water quality change is analyzed,and the specific cause of water quality change is also discussed.The five thermal springs have the hydrochemical characteristics of rich sodium,high sulfate,high fluoride and high metasilicic acid.And,spring water is compound physiotherapy hot mineral water being rich in fluorine and silicon.The overall trend of water quality change is that the content of HCO_(3)^(-)shows an obvious upward trend,the content of SO_(4)^(2-),Na^(+),F^(-),H_(2)SiO_(3)shows an overall downward trend,and that the downward trend of H_(2)SiO_(3)is particularly obvious.The causes for this change are listed as follow.Because of the continuous large-scale development for more than ten years,the exploitation volume is increasing,the thermal reservoir pressure is gradually decreasing,it leads to the increase of the proportion of shallow cool groundwater mixed,and the above changes of water quality.
