摘　　要：污染含水层深度、药剂在饱和层介质中的迁移扩散能力等因素是原位化学氧化技术修复效果的决定性因素,其中注入方式对药剂在饱和层介质中的迁移扩散能力具有重要影响。本文基于工程案例实际应用,引入高密度电阻率法、电磁感应大地电导率法等药剂迁移扩散表征手段,研究分析直压注射法、注入井法、浅层搅拌法等药剂投加与分散技术的适用性、控制参数及优缺点等。The depth of the polluted aquifer,as well as the migration and diffusion ability of the agent in the saturated layer medium,are the decisive factors for the remediation effect of in-situ chemical oxidation technology.Among them,the injection method has an important impact on the migration and diffusion ability of the oxidant.This article introduced the high-density electrical resistivity tomography and the electromagnetic induction type soil conductivity to characterize the migration and diffusion of the oxidant through the practical application of engineering cases.The applicability,control parameters,advantages and disadvantages of oxidant injection and dispersion technologies such as direct pressure injection method,injection well method,and shallow stirring method were studied and analyzed.
