Abstract

The invention discloses an electric power control and repairing system and an electric power control and repairing method of nonaqueous phase liquid pollutants in soil. The electric power control and repairing system consists of an electrode well, a conductive electrode, an insulating electrode, a power supply control system as well as an injected liquid mixing device, an injection pump, an injection well and a sucking well. Aiming at nonaqueous phase liquid pollution of soil, a non-uniform fragrance variable electric field is applied, together with the solubilization of a surfactant, electroosmosis, electrophoresis and dielectrophoresis effects as migration driving power of pollutants are applied to nonaqueous phase liquid pollutants, and the migration direction of the nonaqueous phase liquid pollutants in soil can be changed and controlled, so that the purposes of solubilization, migration control and final enrichment and removal of the nonaqueous phase liquid pollutants in soil and underground water are achieved. In addition, the electric power control and repairing system and the electric power control and repairing method can be also used for controlling the pollution range of nonaqueous phase liquids to be within or outside a specific spatial area.

Description

technical field [0001] The invention relates to soil pollution control and repair technology, in particular to an electrodynamic control and repair system and method for non-aqueous liquid pollutants in soil. Background technique [0002] With the development of modern industrial and agricultural production, some natural or synthetic substances continue to enter the soil surface and aquifer, such as landfill leakage, oil well mining, etc., resulting in continuous occurrence of soil environmental pollution accidents. Most of soil chemical pollutants have "three-cause" effects (carcinogenic, teratogenic and mutagenic). These substances cause persistent pollution to soil, groundwater, organisms and other media, endangering ecosystems and human health. Most organic substances have very little solubility in water, and such pollutants are usually called non-aqueous phase liquids (NAPLs). The non-aqueous phase liquid and the water phase in contact with it migrate slowly, and in ad...
