Exploration of methods for Cr(Ⅵ) pollution remediation in karst groundwater

摘要:
通过调查研究污染物在地下水系统中迁移转化产生的现象，对污染物在自然状态下迁移转化的水动力方式，即水力梯度或浓度梯度作出判断。在此基础上，选择适宜部位人为地为地下水中铬污染物提供水动力条件，迫使污染物有组织地从地下水系统中迁移出来，并进行处理或就地转化。根据重点污染部位的污染现象，研究形成了6种污染治理方法。其中5种方法进行了现场实施和验证。
Abstract:This study investigated the migration and transformation of pollutants in the groundwater system, focusing on the hydrodynamic mechanisms involved, that is, the hydraulic gradient or concentration gradient. The appropriate are is then selected to artificially provide hydrodynamic conditions for groundwater pollutants, facilitating the systematic migration of pollutants, either for treatment or in-situ transformation. Based on the pollution patterns observed in key contaminated zones, six pollution control methods were developed. Five of these methods have been implemented and validated through on-site testing.
