NOVEL TECHNOLOGY FOR CATALYTIC DEGRADATION OF VOCS USING ELECTRO-FENTON

摘要

The present application relates to the field of atmospheric treatment, in particular to a novel technology for catalytic degradation of VOCs using Electro-Fenton. VOCs mixed gas enters a solution from the bottom of a reactor by means of microporous aeration. In this system, a Fenton reaction constructed by anodic oxidation and cathodic catalysis producing H₂O₂ can produce a large number of strong oxidizing hydroxyl radicals, and the active species can oxidize VOCs entered the reaction system by means of aeration into products such as soluble intermediate products, carbon dioxide, water, inorganic substances, etc. In addition, the aeration process of VOCs can provide sufficient oxygen for cathodic catalytic reduction, thereby improving the output of H₂O₂. A lift pump is used for lifting the solution to the top of a reaction device so as to form mist spray by means of a spraying device, thereby further increasing the contact time and the contact area of VOCs and the solution and improving treatment efficiency.
