The development of waste incineration flue gas desulfurization,denitrification,particulate matter and dioxin removal technologies was reviewed,and three current ultra-low emission routes of waste incin-eration flue gas were summarized,namely route 1,SNCR furnace denitrification→ mechanical rotary spray semi-dry deacidification→ assisted dry deacidification→ activated carbon adsorption → bag filter→ wet scrubber/SCR denitrification→ SCR denitration/wet scrubber;route 2,PNCR denitrification → semi-dry deacidification → bag filter → wet scrubber;route 3,dry deacidification → bag filter→ steam heater→SCR out-of-stock → wet scrubber→ wet electrostatic precipitator.By analyzing the collaborative removal mechanism of each target pollutant removal equipment on other pollutants in the route,it is found that the flue gas purification equipment in each route has less influence on each other.On this basis,several inte-grated technologies for the coordinated removal of multiple pollutants from waste incineration flue gas are introduced,and the development direction of the multi-pollutant collaborative removal technology of waste incineration flue gas is prospected in the future.
