Recycling Method for Copper Sulfate Waste Liquid Generated during Build-Up Process and Agricultural Copper Sulfate Fertilizer produced by the Recycling Method

摘要

The present invention relates to a method for recycling copper sulfate waste generated in the build-up manufacturing process and to an agricultural copper sulfate fertilizer produced therefrom, and more particularly, to remove impurities contained in copper sulfate waste generated in the build-up manufacturing process, and evaporate It relates to a method for obtaining high-purity and high-concentration copper sulfate through a concentration process and filtration and dehydration and using it as an agricultural copper sulfate fertilizer. The recycling method of copper sulfate waste generated in the build-up manufacturing process according to the present invention comprises: an impurity removal step (S100) of removing impurities contained in the copper sulfate waste; It includes an evaporation-concentration step (S200) of preparing the formed evaporated concentrate; and a filtering and dehydration step (S300) of filtering and dehydrating the evaporated concentrate to precipitate copper sulfate crystals.
