娘子关泉域岩溶地下水SO_4^(2-),Ca^(2+),Mg^(2+)污染分析

POLLUTION ANALYSIS OF SO 2- 4,Ca 2+ ,Mg 2+ IN KARST WATER IN NIANGZIGUAN SPRING AREA

分析了娘子关泉域岩溶地下水ＳＯ２－４，Ｃａ２＋，Ｍｇ２＋等组分含量增多的原因，并定量地探讨了ＳＯ２－４，Ｃａ２＋，Ｍｇ２＋的各种来源比例。研究表明，含水层中石膏溶解及硫化物氧化是造成ＳＯ２－４，Ｃａ２＋，Ｍｇ２＋高含量的主要原因，控制硫化物氧化水进入含水层，对水质改良有显著效果。

The causes of high concentration of SO 2- 4,Ca 2+ and Mg 2+ in karst water in Niangziguan spring area are analyzed,and the mixing proportions of SO 2- 4,Ca 2+ and Mg 2+ from different sources are quantitatively discussed.The research shows that the high concentration of SO 2- 4,Ca 2+ and Mg 2+ is mainly caused by gypsum dissolving and sulfide oxidation in aquifer bed.Preventing sulfide oxidation water from seeping into ground water will remedy water quality efficiently
