Abstract: The present invention provides a method for treating a flue gas, comprising: step (A) desulfurizing a flue gas to obtain a desulfurized flue gas comprising NO x , SO x , and CO 2 ; step (B) providing oxygen for an oxidization to obtain an oxidized flue gas; step (C) rinsing the oxidized flue gas with water to obtain a rinsed flue gas and a nitric acid solution; and step (D) contacting the rinsed flue gas with a basic solution to absorb the CO 2 in the rinsed flue gas. The method for treating a flue gas can largely reduce the content of CO 2 and NO x in the flue gas. Besides, the obtained product can be used as a carbon source and nitrogen source for algae cultivation.
