Abstract

The invention provides a micro-interface enhanced oxidation system and an oxidation method for preparing hydrogen peroxide, wherein the micro-interface enhanced oxidation system includes: an oxidation reactor, wherein a top portion of a side surface is provided with a liquid phase pipeline for delivering hydrogenated anthraquinone, and a bottom portion of the side surface is provided with a gas phase pipeline for delivering air; and a liquid distributor, a packing section, a seal pan and a hybrid micro-interface unit that are arranged in order from top to bottom are arranged in the oxidation reactor, wherein the hybrid micro-interface unit comprises a upper-mounted micro-interface generator and a lower-mounted micro-interface generator that are communicated with each other up and down, and the hydrogenated anthraquinone delivered in goes down in turn until being mixed with the air in the hybrid micro-interfacial unit to be dispersed and crushed after being distributed through the liquid distributor.
