The invention relates to the technical field of comprehensive utilization of wastewater of phosphoric acid workshops, in particular to a device and a method for adjusting phosphoric ore pulp with wastewater to produce phosphoric acid. Due to structural arrangement of the device, phosphoric ore pulp is filtered by using a ceramic filter before being fed into a phosphoric acid extraction device, further sized and fed into the phosphoric acid extraction device; a liquid obtained through filtering is fed into an ore pulping workshop for circulation treatment, then water can be circulated, a phosphorus element is enriched, the wastewater is relatively high in extraction efficiency after being fed into the phosphoric acid extraction device, the emission amount of the wastewater is reduced, and the cost is reduced; in addition, after filtration treatment of the ceramic filter, and sizing treatment on filter residues, the phosphoric ore pulp is fed into the phosphoric acid extraction device, ore residue components in
