南水北调水进京后部分水源将通过潮白河河道人工回灌至地下储存，以涵养严重亏损的地下水资源。为研究回灌过程中的水岩相互作用，本研究在潮白河河道开展了现场淋溶试验，通过测试分析K＋、Na＋、Ca2＋、Mg2＋、HCO－3、Cl－、SO2－4、NH3?N、NO2?N、NO3?N、F－、溶解性总固体、总硬度、pH值等水质指标的变化特征，从水岩相互作用的角度探讨了水质变化机理，为南水北调水资源的合理利用提供技术支撑。试验结果表明，回灌水源在包气带介质运移过程中物理淋溶现象显著，试验过程中发生了阳离子交换吸附作用、氨氮解析和硝化作用等一系列的化学反应。
Part of water resources of South?to?North Water Diversion Project will be artificially recharged to underground to conserve groundwater resources. Leaching experiment was carried out in Chaobai River to study water?rock interaction. The variation characteristics of water?quality indexes including K+,Na+,Ca2+,Mg2+,HCO-3 , Cl-,SO2-4 ,NH3?N,NO2?N,NO3?N,F-,total dissolved solids, total hardness, pH were analyzed and the mechanism of water quality variation from the perspective of water-rock interaction was discussed to provide technical support for the rational use of water resource of South to North Water Diversion Project. The test results showed that physical eluviation is significant and cation exchange adsorption, desorption and nitrification of ammonia nitrogen occurred in the test.
