description The utility model discloses an aluminum nitrate-containing nitric acid wastewater treatment system which comprises a two-stage column-passing separation system and an aluminum sulfate purification system, the aluminum sulfate purification system comprises an aluminum sulfate feeding tank, a preheater, a two-effect three-stage falling film evaporator used for multiple times of evaporation and concentration of an aluminum sulfate solution, a cooling crystallization tank, a crystallization transfer tank, a filter press, a high-level tank used for receiving a solid obtained after filter pressing and a scraper machine which are connected in sequence. And the aluminum sulfate feeding tank is connected with the aluminum sulfate solution tank. The aluminum nitrate-containing nitric acid wastewatertreatment method based on the wastewater treatment system is small in evaporation capacity and relatively low in production risk; the replacement is thorough, the content of nitric acid in the obtained aluminum sulfate solut
