Fenton reaction dosing device

The utility model discloses a Fenton reaction dosing device which comprises a continuous water inlet device for conveying sewage, a hydrogen peroxide storage tank for storing a hydrogen peroxide solution, a ferrous sulfate storage tank for storing a ferrous sulfate solution and an ejector communicated with a Fenton reactor, and the ejector is communicated with the continuous water inlet device through a power pump; the jet devices comprise the first jet device and the second jet device, the first jet device is communicated with the hydrogen peroxide storage tank, and the second jet device is communicated with the ferrous sulfate storage tank. As the two agents are fully mixed with the sewage and enter the Fenton reactor, the two agents are in rapid contact and react to generate hydroxyl radicals, and the generated hydroxyl radicals are relatively uniformly distributed in the sewage, the hydroxyl radicals can rapidly react with macromolecular pollutants in the surrounding sewage, the reaction efficiency of the
