Summary:The invention relates to a method for removing VOCs (volatile organic chemicals) by ozone and photolytic peroxide. According to the method, the VOCs from a discharging source are firstly pre-oxidized into organic intermediate by the ozone in a flue, ultraviolet light excites the peroxide to generate sulfate radical and hydroxyl free radical, so that the VOCs and the organic intermediate generated by oxidization of the ozone are further oxidized, and final decomposition products are harmless CO2 and harmless H2O. The VOCs in flue gas can be efficiently removed, secondary pollution is avoided in the removing process, and a novel VOCs purification system has a wide application prospect.
