Flue gas treatment process for solid waste incinerator

The invention relates to a flue gas treatment process for a solid waste incinerator. The flue gas treatment process comprises the steps of dust removal treatment, alkali washing neutralization treatment and oxidation denitration treatment. An oxidation denitration unit is adopted to carry out ozone-based oxidation denitration treatment on the flue gas subjected to alkali washing and neutralization treatment, and then the flue gas is discharged; the oxidation denitration unit comprises an ozone generating device; the ozone generating device comprises an ozone generator and a plurality of ozone feeding points connected with the ozone generator through an ozone conveying pipeline. According to the flue gas treatment process for the solid waste incinerator, the overall equipment investment and NOX conversion efficiency of the denitration process are high, the production safety is high, a catalyst does not need to be used, the problem of severe poisoning or inactivation of the catalyst does not need to be consider
