| Summary: | The present invention provides a system for recycling spent sulfuric acid, which aims at providing an industrially advantageous system featuring that spent sulfuric acid is effectively utilized at a place other than a discharge source regardless of geographical conditions, and also provides a method for recycling waste sulfuric acid, and recycled sulfuric acid. In the system, when spent sulfuric acid discharged or collected at a discharge source A is transported by a carrier unit B, and used at a user office C, a concentration of the spent sulfuric acid is measured and/or adjusted at least at one of the discharge source A, the carrier unit B, and the user office C. The spent sulfuric acid waste liquid discharged or collected at the discharge source A is reutilized by being mixed with at least one of a hydrogen peroxide solution and water. |
