The utility model discloses a waste sulfuric acid treatment device, including waste sulfuric acid collecting vessel, filter equipment, electrical heating distillation plant, dog-house, reaction tank, waste water discharge port. Through the device, after the waste sulfuric acid is subjected to precipitation, filtration and heating distillation, the recovered concentrated sulfuric acid reacts with aluminum hydroxide to generate aluminum sulfate, so that on one hand, the problem of treatment of the waste sulfuric acid is solved, and on the other hand, the waste sulfuric acid is changed into a waste material which can be used as a flocculating agent for industrial wastewater treatment; furthermore, the five-layer structure of the filter device enhances the filtration efficiency on the one hand and also reduces the sulfuric acid back-flushing on the other hand. |
