Provided is a method for desulphurizating and denitrating a flue gas in an integrated manner based on low-temperature adsorption. The method includes: decreasing a temperature of the flue gas below a room temperature by using a flue gas cooling system; removing moisture in the flue gas by using a dehumidification system; sending the flue gas to a SO.sub.2 and NO.sub.x adsorbing column system; and simultaneously adsorbing SO.sub.2 and NO.sub.x of the flue gas with a material of activated coke, activated carbon, a molecular sieve or diatom mud in the SO.sub.2 and NO.sub.x adsorbing column system to implement an integration of desulphurization and denitration of the flue gas based on the low-temperature adsorption. With the present method, SO.sub.2 and NO.sub.x of the flue gas can be adsorbed simultaneously in an environment having a temperature below the room temperature.
