水文地球化学热力学在山西省辛安泉氮污染预测中的运用

The Application of Hydrogeochemistry Thermodynamics in Prediction of Nitrogen Pollution in Xinan Spring,Shanxi

山西省辛安泉是长治地区的主要供水水源，目前它的部份泉域已遭到了严重的氮污染，本文在环境水文地质地球化学调查的基础上，应用水文地球化学热力学理论，对氮化物（ＮＨ＋４，ＮＯ－２，ＮＯ－３）在岩溶水中转化方向，平衡组成进行了分析，并用稀释环境容量方法，作出了辛安泉氮污染预测初步评价，这表明在水文地质地球化学研究程度不足以建立溶质运移确定型模型时。

The Xinan Spring is one of major springs in the north China and the main water source in spring zone.But it has been polluted partly at present Based on the investigation of hydrogeology and hydrogeochemistry,the regularity of transport and transformation of nitrogen(NH + 4,NO - 2,NO - 3)in limestone is studied according to the theory of hydrogeochemistry thermodynamics,and the preliminary prediction of nitrgen pollution is accomplished in Xinan Spring by the method of environmetal capacity Therefore it can be approved that hydrogeochemisty theory is effective in the prediction of nitrogen pollution when the hydrogeochemistry conditions are not enough to establish a solute transport model
