Abstract

The invention belongs to the technical field of organically polluted groundwater treatment, and especially relates to a system for restoring organically polluted groundwater through supersonic wave combined photo-Fenton oxidation, and a method thereof. The main body of an apparatus is a supersonic wave combined photo-Fenton oxidation reaction tower, parts comprising a supersonic generator, an ultraviolet lamp, a TiO2 catalyst coating, a pH-t monitor and a mixer are arranged in the tower, and the tower, the parts, a gas recovery and purification treatment device, a condenser, a Fenton reagent box, an acid-alkali tank, a water storage box, pipelines and various pumps form the complete restoration apparatus. The synergistic effect of the supersonic waves, ultraviolet lights and Fenton oxidation substantially improves the oxidation degrading treatment efficiency of organic matters, and realizes the second pollution-free, efficient and thorough restoration of organic matter polluted groundwater.

Description

technical field [0001] The invention belongs to the technical field of organic-polluted groundwater treatment, and in particular relates to a system and method for repairing organic-polluted groundwater by ultrasonic combined with photo-Fenton oxidation. Background technique [0002] With the continuous and efficient development of my country's economy, human activities continue to intensify, and groundwater pollution is becoming more and more serious. This not only restricts agricultural production and industrial development more and more, but also affects people's health. Among them, organic pollution is a major category of groundwater pollution. It is mainly discharged into the environment in the form of industrial waste, residual pesticides, organic wastewater, and domestic garbage through various channels, thereby polluting groundwater. Moreover, these organic pollutants are characterized by their persistence, high toxicity, accumulation, and fluidity. They will accumu...
