摘要
针对岩溶区地下水易受到污染的情况,以柳州市竹鹅溪片区为研究对象,研究岩溶地下水污染特征。在对竹鹅溪片区的5个地下水监测点先后进行6次取样检测,检测的26项指标中污染比较严重的水质指标有总硬度、挥发性酚类、硝酸盐、氨氮、镉和总大肠杆菌群,其余20项指标检测含量都在《地下水质量标准》(GBT14848-93)的Ⅱ类水标准限值内。依据检测结果对地下水的水质现状进行评价,并且结合竹鹅溪片区的水文地质条件、污染源现状调查情况、地表水检测结果等分析了地下水水质指标中超标及污染严重的成因,对研究该片区地下水污染防护措施具有一定的应用价值。
Karst groundwater is easy to be polluted. The characteristics of karst groundwater pollu- tion of Zhu-e Creek in Liuzhou city were studied on the basis of six samples taken from each of five groundwater monitoring points of Zhu-e Creek. Six of the 26 water quality indicators of the samples, including total hardness, volatile phenols, nitrate, ammonia nitrogen, cadmium and total coliforms, were over the quality standard for ground water. The others were within the standard limit. The quality of groundwater was evaluated according to the test results. Considering the hydrogeological condition, the pollution source situation and the surface water test results of Zhu-e Creek, the causes of over-standard and heavy pollution in the groundwater were analyzed. Conclusions drawn from this study would provide a reference for the pollution prevention of underground water in karst areas.
