安徽淮北临涣矿区地表水水化学及硫氢氧同位素组成特征
|
摘要
以淮北临涣矿区为研究对象,系统的采集了研究区河水、沉陷区积水和矿井排水等共23个水样,分析测试其常规水化学指标及氢氧硫同位素特征值。采用Piper三线图、Gibbs图与线性回归分析等方法,探讨了研究区不同类型地表水水化学组份特征及影响因素、SO_4~(2-)来源等问题。结果表明:研究区地表水TDS含量较高,属高矿化度水质类型,阳离子主要为Na~+和Ca~(2+),阴离子主要为HCO3-与SO_4~(2-),其中浍河河水水化学类型主要为Na~+-Ca~(2+)-HCO_3~-型,沉陷积水主要为Na~+-Cl~--SO_4~(2-)型;研究区河水和沉陷区积水SO_4~(2-)含量较高,平均值分别为412. 90 mg/L和490. 61 mg/L,河水中SO_4~(2-)主要来源于蒸发岩溶解、废水排放,沉陷区积水SO_4~(2-)来源于河水补给及矿井排水的影响;地表水的δD和δ~(18)O值变化范围为-55. 3‰～-29. 3‰和-7. 2‰～-2. 6‰,均落在大气降水线下方,表明其受到不同程度蒸发作用,河水、沉陷积水主要补给来源是大气降水; Gibbs图分析结果表明河水离子组成主要受岩石风化的控制,而沉陷区积水主要受蒸发作用影响。
Taking the Linhuan mining area in Huaibei as the research object,a total of 23 water samples were systemic collected from the river,the subsidence area and the mine drainage in the study area. The conventional hydrochemical indexes and hydrogen,oxygen and sulfur isotope eigenvalues were analyzed and tested. Piper three-line diagram,Gibbs diagram and linear regression analysis were used to investigate the characteristics and influencing factors of different types of surface water and water components in the study area,and the source of SO_4~(2-). The results showed that content of total dissolved solids of the surface water was high in the study area,which belonged to the high salinity water quality type. The cations are mainly Na~+ and Ca~(2+),and the anions were mainly HCO_3~- and SO_4~(2-). The chemical type of the Huihe River was mainly Na~+-Ca~(2+)-HCO_3~-. Subsidence area water was mainly Na~+-Cl~--SO_4~(2-) type; the content of SO_4~(2-) was higher in the river water and subsidence area of the study area,the average values were 412. 90 mg/L and 490. 61 mg/L,respectively,and SO_4~(2-) in river water was derived from the dissolution of evaporite,wastewater discharge,and SO_4~(2-) was derived from the effects of river water supply and coal mining activities in the subsidence area; the range of δD and δ~(18)O values of surface water was-55. 3‰ ～-29. 3‰ and-7. 2‰ ～-2. 6 ‰,respectively,all fall below the atmospheric precipitation line,which indicated that it was affected by different degrees of evaporation. The main source of water supply for river water and subsidence was atmospheric precipitation. Gibbs chart analysis showed that the composition of river water ions was mainly controlled by rock weathering,while the water mainly affected by evaporation in subsidence area.
