以重金属铬为地下水污染物，研究了原位电化学动力修复技术的具体应用，分析了恒压条件和恒流条件的电化学动力原理，开展了污染地下水的修复模拟试验，揭示了电场作用下地下水中重金属迁移规律。成果表明：该法对地下水重金属污染修复效果较好，Cr(Ⅵ)的去除率达到99.95%以上，出水浓度满足相关标准，应用于实际工程是可行的。

As a kind of groundwater pollutant, chromium metal was taken as a subject investigated in the paper, then the specific application of insitu electrochemical dynamic repairing technique was researched and electrochemical dynamic principle in constant voltage and constant current was analyzed. Meanwhile, repairing simulated tests of static and dynamic pollution to groundwater were carried out；migrating regulation of heavy metal in groundwater under electric field was also uncovered. It is indicated by test results that repairing effects to heavy metals in groundwater by this technique is quite well, and it is feasible in practical engineering application, and that the removal efficiency of Cr(Ⅵ) will be over 99.95%, meanwhile, outflow concentration will meet related standards.
