潮白河地下水调蓄区水岩作用过程模拟
|
摘要
南水北调中线工程通水后,将有部分结余水量用于补给潮白河地下水调蓄区。由于南方地表水(以下简称南水)与北京当地地下水的水质存在一定差异,回灌过程中很有可能发生水岩相互作用。研究以潮白河地下水回灌区为例,通过静态摇瓶实验和水文地球化学模拟等研究方法,对南水补给北京深层地下水过程中产生的水岩作用过程和水质影响程度进行分析评价。研究结果表明:南水回灌过程中,地下水的主要离子成分会受到硝化作用、阳离子交换作用及包气带矿物质溶解等作用的综合影响。两种水混合过程中,土壤矿物相中的方解石和白云石不断溶解,Ca2+、Mg2+浓度逐渐升高,反应过程中还伴随强烈的阳离子交换作用,主要为Na+与Ca2+、Mg2+的交换。南水比例越大,溶解氧促进硝化作用越明显;在硝化作用和碳酸平衡的共同影响下,地下水的pH值呈现先降低后升高的趋势。
In the process of The South-to-North Water Transfers,some of the water will be used to supplement the groundwater of Chaobai River basin.Due to the differences of Danjiangkou reservoir water and Beijing groundwater,water-rock interaction may occur.Taking the example of Chaobai River basin,we analyzed the water-rock interaction and changes of water during recharge by batch experiments and hydrogeochemistry simulation.The results showed that:during the recharge,the water was affected by nitrification,cation exchange and solution of minerals.With the increase of proportion of southern water,calcite and dolomite dissolve and concentrations of calcium and magnesium were elevated coupled with cation exchange which mainly is sodium with calcium and/or magnesium.The higher proportion of south water,the stronger of nitrification is found.Affected by nitrification and carbonate balance,pH of groundwater was reduced at early stage then elevated at late stage.
