潮白河地下水调蓄区水岩作用过程模拟
Simulation of the water-rock reaction in Chaobai River ground-water storage area
摘要
Abstract
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 re-charge by batch experiments and hydrogeochemist ry simulation. The results showed that: during the recharge, the water was af-fected by nitrification, cat ion exchange and solution of minerals. With the increase of proport ion of southern water, calcite and dolomite dissolve and concentrations of calcium and magnesium were elevated coupled with cation exchange which mainly is so-dium with calcium and/ or magnesium. The higher proportion of south water, the stronger of nitrification is found. Affect ed by nitrif ication and carbonate balance, pH of groundwater was reduced at early stage then elevated at late stage.关键词
