Abstract

Taiwan hot spring is rich in resources, in addition to the sodium bicarbonate spring, but also includes cold spring. Cold spring Including low temperature and rich in free carbon dioxide. Because the hot springs and cold spring characteristics are different and need for heating or cooling before soaking. Heating and cooling action of hot spring water quality of the situation is also different. Therefore, this study explores the relationship between water quality and temperature. In this study, four kind of cold springs were selected to temperature test. After heated the spring water, then let the springs cool down naturally. the test process at the same time measuring water quality changes. Draw relationship curves to observe the correlation between water temperature and water quality changes. The results show that the total dissolved solids (TDS) show a continuous increase during the test, which is the main factor affecting the cooling rate of hot spring. Conductivity is positively correlated with temperature, pH increased, free carbon dioxide decreases, oxidation reduction potential is higher with the reduction of the test process. Suao cold spring heating temperature exceed 50 °C, the free carbon dioxide value will drop below 500 ppm. Nantong cold spring temperature exceed 46 °C, the pH will be acidic to alkaline phenomenon.
冷热温泉水温及水质变化的研究
台湾温泉资源丰富,除碳酸氢钠温泉外,还包括冷泉。冷泉包括低温和丰富的游离二氧化碳。因为温泉和冷泉特性不同,在浸泡前需要加热或冷却。加热和冷却作用对温泉水质的影响情况也不同。因此,本研究探讨水质与温度的关系。本研究选取四种冷泉进行温度试验。把泉水加热后,让泉水自然冷却。测试过程中同时测量水质的变化。绘制关系曲线,观察水温与水质变化的相关性。结果表明:在试验过程中,总溶解固形物(TDS)呈持续增加的趋势,是影响温泉冷却速率的主要因素;电导率与温度呈正相关,pH值升高,游离二氧化碳降低,氧化还原电位随测试过程的降低而升高。冷泉加热温度超过50℃,游离二氧化碳值将降至500ppm以下。南通冷泉温度超过46℃,pH值就会出现酸转碱性现象。
