The invention discloses a flue gas ammonia synchronous desulfurization and denitrification process based on electrolytic regeneration to remove iron, which solves the problem of low regeneration efficiency of absorption liquid in the existing desulfurization and denitrification process. The technical scheme includes that after the flue gas is pressurized, it is sent to the concentration tower to contact and react with the concentrated liquid in the tower. After iron removal by the first electrolytic reactor, it is sent to the ammonium sulfate crystallization system. The absorbed liquid after partial reaction at the bottom of the absorption tower is regenerated and returned to the upper part of the absorption tower as a circulating absorption liquid. The concentrated liquid first enters the first electrolytic reactor The anode chamber in the reaction unit undergoes an oxidation reaction, and then enters the cathode chamber to undergo a reduction reaction; the reacted electrolyte is discharged from the short outlet pipe of the reactor and sent to the ammonium sulfate crystallization system. The invention has the advantages of simple method, low investment cost and operation cost, high conversion efficiency, good iron removal effect, and good desulfurization and denitrification effect.

The invention relates to a method for purifying and deferrizing an electrolytic manganese leach solution, which comprises the following steps: when a compound leach solution of electrolytic manganese metal reaches to the leaching reaction end point, determining the total content of Fe<2+> in the leach solution, and adding MnO2, which is 0.6-1.2 times of the theoretical amount required by completely oxidizing all the Fe<2+>, into the leach solution; after finishing adding the MnO2, continuing stirring to react, determining the residual total content of Fe<2+> in the leach solution, and adding a strong oxidizer required by completely oxidizing the residual Fe<2+> so as to lower the concentration of the residual Fe<2+> to below 1mg / L; regulating the pH value of the solution with a neutralization reagent, and detecting the concentration of the Fe<2+> in the solution; and removing solid impurities from the solution by using a filter plant. The invention provides an oxidizing and deferrizing method by combining MnO2 and a strong oxidizer; and on the premise of ensuring the deferrizing effect, the invention prolongs the leaching reaction time, increases the concentration of Mn<2+> in the solution and lowers the deferrizing cost.
