The invention discloses a method for carrying out oxidation denitration on sintering flue gas by using chlorine dioxide, and mainly solves the problem of low denitration efficiency in the existing sintering flue gas desulfurization and denitration process. The method for carrying out oxidation denitration on sintering flue gas by using chlorine dioxide comprises the following steps: 1) carrying out electric precipitation on the sintering flue gas; 2) performing desulfurization and denitrification treatment on the sintering flue gas, firstly introducing chlorine dioxide into the sintering flue gas after machine head electric precipitation treatment, then conveying the sintering flue gas to an absorption tower through a pipeline, and controlling the temperature of the sintering flue gas entering the absorption tower to be 85-120 DEG C; and 3) carrying out cloth bag dust removal on the sintering flue gas. According to the method, the desulfurization rate of the sintering flue gas is greater than or equal to 98%,
