AI Technical Summary
Technical Problem
Traditional chemical oxidation methods or biological treatment techniques are difficult to effectively degrade organic pollutants in water bodies, and the Fenton method requires continuous addition of H2O2, which limits its practical application.
Method used
Coupled photocatalytic technology with Fenton technology, use photocatalysts to generate H2O2 under light, and react with Fe2+ in iron-containing sludge in the Fenton reaction tank to generate strong oxidative ∙OH and degrade pollutants in situ.
Benefits of technology
It realizes efficient degradation of organic pollutants in water without the need for additional H2O2, reduces the pollution of iron-containing sludge to the environment, and reduces the cost of sewage treatment.

Abstract
The present invention provides a self-Fenton pollutant degradation device for in-situ photocatalytic H2O2 production, the structure of which includes a photocatalytic reaction pool (2) and a Fenton reaction pool (3); wherein the water outlet of the photocatalytic reaction pool (2) is connected to the water inlet of the Fenton reaction pool (3); the interior of the photocatalytic reaction pool (2) includes a light source (10) and a photocatalytic unit (11); the interior of the Fenton reaction pool (3) includes an acidification pool (16) and an iron source carrier (18), and the iron source carrier (18) is equipped with an iron source. The present invention couples the photocatalytic technology with the Fenton technology, directly produces the required H2O2 in the photocatalytic stage, overcomes the disadvantage of the traditional Fenton technology that the H2O2 needs to be continuously added, and uses the recycled iron-containing sludge as the iron source to achieve waste treatment with waste.
