The utility model discloses a device for implementing up-to-standard emission of boiler smoke by means of the coupling technology. The device comprises a static efficiency dust remover, wherein the static efficiency dust remover is connected with a draught fan through a smoke flue I, the other end of the draught fan is connected with an inlet of a desulfurizing tower through a smoke flue II, and an outlet of the desulfurizing tower is connected with a chimney through a smoke flue III. A mixing device is arranged in the smoke flue I, an ozone generation device is connected with the mixing device through an ozone conveying pipeline, and a process water tank is connected with the static efficiency dust remover and the ozone generation device through water conveying pipelines. By means of measures of locally modifying an existing static efficiency dust remover, additionally arranging the ozone generation device and the like, the three technologies of static efficiency dust removal, ozonation and wet type adsorption are coupled successfully. There's no need to construct units of an oxidation reactor, an absorption tower and the like when the technology is implemented, and therefore, the device has the advantages of being capable of saving investment, small in floor space and modification workload, low in operation cost and the like.
