Evolution treatment is performed on heavy metal ions and other impurities in the sulfate solution generated by pre-desulfurization.
Main process flow:
· The filtrate after pre-desulfurization is sent to the purified raw liquid storage tank. · The filtrate adjusts the pH value in the reaction tank and adds the purification reagent. · After passing the inspection, it is stored in the storage tank
Technical indicators:
· A. Ammonium sulfate solution: 25-35%, the heavy metal content of the solution after treatment is <10PPM · B. Sodium sulfate solution: 16-28%, the heavy metal content of the solution after treatment is <10PPM
