description The invention relates to a flue gas desulfurization and denitrification method for coupling pricing oxidation with nitrogen-sulfur synergistic absorption, and relates to the technical field of flue gas desulfurization and denitrification. The method comprises the following steps: firstly, carrying out pricing catalytic oxidation on flue gas by virtue of a catalyst, hydrogen peroxide and ozone, and carrying out pricing oxidation on NO in the flue gas into NO2, so as to obtain oxidized flue gas; then carrying out nitrogen-sulfur synergistic absorption on the oxidized flue gas by utilizing absorption slurry to realize flue gas desulfurization and denitrification; the used catalyst is a Co < x > Mn < 3-x > O < 4 > nano metal oxide. The problem that the nitrogen oxide absorption efficiency is low is solved with low cost, and final flue gas ultra-low emission is achieved. The absorbent disclosed by the invention can efficiently and synergistically absorb nitrogen and sulfur flue gas mainly containing nitrogen dioxi
