Preparation method of chicken house micro-nano zinc deodorant

The invention provides a preparation method of a chicken house micro-nano zinc deodorant. The preparation method comprises the following steps: preparing a zinc particle solution by using a microemulsion method; transferring the prepared zinc particle solution into a next reaction kettle, and preparing a micro-nano zinc solution A by utilizing a cavitation erosion phenomenon; adding water to obtain a micro-nano zinc solution B; and adding citric acid, conducting stirring and dispersing to obtain a micro-nano zinc solution C, adding essence and conducting dissolving to obtain a micro-nano zinc solution D, adding an ethanol solution to obtain a micro-nano zinc solution E, adding a dissolved copper sulfate solution to obtain a micro-nano zinc solution F, and stirring the micro-nano zinc solution F at normal temperature to obtain the final chicken house micro-nano zinc deodorant. The chicken farm deodorant can reduce the odor concentration inside and outside a chicken farm and improve the surrounding environment,
