Abstract

The invention provides a device and method for testing the migration behavior of a repairing material in an underground water environment, and the device comprises a migration device for simulating the underground environment, and testing equipment. The migration device comprises a medium groove, a water injection pool, a water outlet pool, an electrode and a repair material injection device, the electrode is arranged in the medium groove and used for being electrically connected with test equipment to monitor the resistivity change of the migration device; and the repair material injection device is used for injecting a repair material into the migration device. According to the device, accurate control over the flow velocity of underground water is achieved by simulating the water flow velocity of the actual underground water environment, it is guaranteed that the real migration condition of the remediation material in the underground water environment is simulated by simulating the chemical environment of the underground water, and the migration behavior of the remediation material is monitored in real time through high-density resistivity imaging equipment; the method has important scientific significance on the migration rule of the remediation material in soil and underground water and the realization of efficient remediation of soil and underground water pollutants.
