The utility model relates to a phosphoric acid workshop multipurpose use of waste water technical field, especially, utilize waste water to adjust device of phosphorite slurry extraction production phosphoric acid, through the structure setting to the device, phosphorite slurry makes before getting into phosphoric acid extraction device, filter the back through porcelain filter, size mixing it again, send into phosphoric acid extraction device, and the liquid that obtains the filtration gets into the grinding building processing that circulates, water makes when obtaining cyclic utilization, enrichment phosphorus element, back among the realization entering phosphoric acid extraction device, its extraction efficiency is higher, and waste water discharge reduces, thus the cost is reduced. And behind porcelain filter filtration treatment, size mixing to the filter residue and handle the back, send into among the phosphoric acid extraction device for slay composition in the ore pulp obtains secondary decompositi
