Abstract：This paper presented an overview of technology to upgrade the conventional dilution ventilation for highway tunnel air pollutant removing,surveying the literatures regarding the recent advances,at home and abroad,in air pollution control technology used for highway tunnel,particularly electrostatic dust removing technology,i.e.electrostatic precipitator (ESP) that can remove dust up to 90％.The operation principles of ESP and various methods for removing tunnel pollutants PM,CO and NOx were expounded,and in addition,different installation and arrangement modes of ESP in the tunnel were described.Furthermore,this paper proposed a comprehensive plan for highway tunnel air pollution control by using ESP combined with the other air purification devices,which underlined the role of ESP in removing PM,while gaseous air pollutants such as CO,NOx were better removed by adsorption measures with relative devices,thus the removal efficiency will be greatly improved.Finally,trends in the technical development for highway tunnel air pollution control were prospected.
