The invention relates to a flue gas treatment system and a flue gas treatment method for semi-dry desulfurization and denitrification. The system comprises a plasma oxidation device, a denitration reaction tower, a concentration tower, a desulfurization absorption tower, a sodium carbonate liquid preparation device, a plurality of flue gas pipelines and a plurality of solution pipelines; the denitration reaction tower is communicated with the plasma oxidation device and the concentration tower, and the concentration tower is communicated with the desulfurization absorption tower; the sodium carbonate solution preparation device is communicated with the concentration tower and the desulfurization absorption tower. The flue gas treatment system can realize denitration and desulfurization treatment of flue gas, does not need to adopt separate equipment for respective treatment, and has the advantages of simple structure, high efficiency and good treatment effect. |
