Production process for preparing activated zinc oxide

The invention relates to a production process for preparing activated zinc oxide, which comprises the following steps: adding a copper-zinc-containing raw material into a sulfuric acid solution, stirring for dissolving, and leaching to obtain a zinc sulfate solution; heating the zinc sulfate solution to 70-80 DEG C, adding potassium permanganate into the zinc sulfate solution, and stirring for primary purification, filtration, oxidation and impurity removal to obtain an impurity-removed zinc sulfate solution; adding zinc powder for secondary purification and filtration, and adjusting the pH value of the solution to 5-6 after filtration; adding ammonium bicarbonate for ammonium bicarbonate neutralization treatment until the pH value is 6-7, and separating out wet-based basic zinc carbonate;drying and crushing the wet-based basic zinc carbonate through flash evaporation drying equipment to obtain dry-based basic zinc carbonate; heating and decomposing the obtained dry-basis basic zinc carbonate at high temperat
