摘要
对云南省绥江县新城供水工程的地下水水化学成分作了分析。结果表明,水化学类型以重碳酸盐低矿化度淡水为主,局部地区为重碳酸硫酸盐型水;主要阳离子为Ca^2+、Mg^2+,阴离子为HCO3^-、SO4^2-;pH呈弱碱性(7.3~8.2);矿化度普遍较低(〈0.5g/L),因个别由于煤层的出现导致矿化度增大。
The chemical composition of groundwater in the Water Supply Project Suijiang town of Yunnan province was analysed. The result shous that the most type bicarbonate, low - salinity fresh water, some is heavy - carbonate, sulfate water. Ca^2+, Mg^2+ and the most anions is HCO3^-, SO4^2-. pH is weak alkaline (7.3 - 8.2 ), salinity is generally low( 〈0. 5 g/L).
