Patent ID: 8383074

Claim:
A process for simultaneously desulfurizing and denitrating the flue gas with seawater, characterized in that the process comprises steps: A) catalytically scrubbing the flue gas with the seawater, wherein the flue gas containing SO 2 and NOx is catalytically scrubbed with the seawater to remove SO 2 and NOx from the flue gas, and the purified flue gas after being desulfurized and denitrated and acidic seawater formed during scrubbing are discharged; the catalytic scrubbing refers to iron catalytic scrubbing carried out with the seawater having a certain quantity of iron ions or with the seawater to which a certain quantity of iron ions are added, and/or magnetic catalytic scrubbing carried out by having the seawater and/or the flue gas pass through an applied magnetic field; B) restoring quality of the acidic seawater, wherein the acidic seawater discharged in step A) is mixed with seawater for acid-alkali neutralization and air is blown in, so as to discharge after the quality of the acidic seawater is restored to meet environmental protection requirements.
