The invention discloses an SCR denitration coal-fired power plant liquid slagging boiler waste gas treatment system. The system comprises a boiler slag system, a waste flue gas pollutant purificationsystem, a waste gas SCR denitration system and a waste residue treatment system. The waste residue treatment system comprises a residue pool and a residue fishing machine. The waste flue gas pollutantpurification system comprises a waste gas pipe connector, a waste gas pipeline, a waste gas pipe adjusting door, a waste gas temperature measuring point and a waste gas flow measuring point. The waste gas pipe connector is connected with the waste gas pipeline. The waste gas pipe adjusting door, the waste gas temperature measuring point and the waste gas flow measuring point are all arranged on the inner wall of the waste gas pipeline. The waste gas SCR denitration system comprises a dust remover. The newly added waste gas SCR denitration system and the dust remover, an induced draft fan anddesulfurization tower equip
