Photo-Fenton oxidation reactor to remove 1,4-dioxane and method to remove 1,4-dioxane by Photo-Fenton oxidation

摘要

An object of the present invention is to provide a 1,4-dioxane-containing wastewater generated in a polyester manufacturing process and rapidly remove 1,4-dioxane concentration with high efficiency in a Fenton reactor equipped with UV lamps. And 4-dioxane-containing wastewater treatment apparatus and method.;The present invention is a wastewater inlet for introducing a 1,4-dioxane-containing wastewater; A conveying pump and a conveying pipe for conveying the introduced wastewater into and out of the apparatus; UV lamp for ultraviolet irradiation; And it provides a 1,4-dioxane photolysis device by the photo-Fenton oxidation comprising a diffuser for producing fine compressed air.;The present invention also provides a 1,4-dioxane photolysis method by the Fenton oxidation process, wherein the contact of 1,4-dioxane-containing wastewater with Fenton's reagent and ultraviolet rays is generated actively by continuously applying compressed air during the Fenton oxidation process. Simultaneously dissolving oxygen contained in air into the wastewater to increase the production of OH radicals by reaction with divalent iron to promote decomposition of 1,4-dioxane; And simultaneously increasing the contact of the Fenton's reagent with 1,4-dioxane and ultraviolet light in the wastewater by continuously returning the reaction solution to the outside of the reactor and recycling the inside of the reactor. Provided is a dioxane photolysis method.;1,4-dioxane, fenton oxide, polyester
