| 摘 要： | 岩溶地下水是焦作市主要饮用水水源,受人类活动影响,局部地下水中铬(Ⅵ)浓度逐渐升高。利用氢氧稳定同位素在辨析不同水体水力联系方面的原理,结合不同水体的水化学组成,判定岩溶地下水中铬(Ⅵ)污染来源。结果表明,研究区岩溶地下水铬(Ⅵ)含量升高与粉煤灰有关,主要污染过程为含铬粉煤灰的灰水渗滤液借助凤凰山断层破碎带进入岩溶地下水G6,同时进入下游岩溶地下水G1,泉水、大气降水、河水以及土壤等不会引起岩溶地下水铬(Ⅵ)含量升高。 |
| 关 键 词： | 岩溶地下水 铬(Ⅵ)污染 粉煤灰 断层 焦作市 |

| Abstract: | As the main drinking water resource for the citizens in Jiaozuo City,karst groundwater was being influenced by anthropogenic activities because hexavalent chromium concentrations in local groundwater became higher and higher slowly.The hexavalent chromium pollution sources were determined by hydrogen and oxygen stable isotopes which were often used for investigating the hydraulic connection between groundwater and surface water,and the hydrochemical composition of different water bodies.The results indicate... |
