摘要
为探析开封沉积岩相地热田地热水中亚硝酸盐增高机理,根据29眼地热井的水质动态检测资料,分析了亚硝酸盐在平面及垂向上的增高趋势及超标情况.利用现场实测的31组“三氮”数据,研究了温度及混入空气时间对地热水中“三氮”质量浓度变化规律的影响.在上述研究的基础上,指出亚硝酸盐增高的机理为:由于地热水的大量开采,导致地热水赋存环境显著改变,或发生硝化作用或发生反硝化作用,致使亚硝酸盐增高.
According to water quality dynamic detecting data of 29 geothermic wells of sedimentary lithofacies geothermal field in Kaifeng. The paper analyzes nitrite＇ s heightening tendency and exceeding standard situation in plane and vertical. With 31 batteries ＂three nitrogen＂ data, the paper researches ＂three nitrogen＂ content changes influenced by temperature and interfusing air＇s time . The result shows： excessive exploitation geothermal water can lead to the change of geothermal water environment or the generation of nitrification or denitrification, which give rise to nitrite heightening.
