摘　　要：将N2、O2、NO、SO2气体按一定比例混合成模拟工业烟气，将混合气体与0，同时通入反应器中。实验中，考察03／NO物质的量之比、温度以及不同的吸收液对脱硫脱硝的影响。实验结果表明，液相中O3对NO能有效氧化，然而S02的存在对NO的去除具有一定的负面影响。当O3／NO=1时，NO的去除率达到93．12％；Na2CO3溶液替代蒸馏水作为吸收液时，有利于NO和S02的去除；当温度在20～60℃范围内，NO和s02的去除率呈逐渐下降的趋势，但影响不大。The gases such as N2, 02, NO and SO2 were mixed at a certain ratio in the lab to sim- ulate industry flue gas. The simulated flue gas and ozone were put to ozone reactor. The effects of the parameters such as O3/NO mole ratio, temperature and different absorption solution on removal effi- ciencies of NO and SO2 were studied. The experimental results showed that NO can be oxidized effi- ciently by O3 in liquid phase, while the existence of SO2 has a negative impact on the removal of NO. Under the condition of 03/NO=1, the NO removal efficiency is 93.12%. When the absorption solu- tion was changed from distilled water to Na2CO3 solution, the removal efficiencies of NO and SO2 in- creased. It can be found that the removal efficiencies of NO and SO2 appeared to have a slight de- cline trend at 20-60℃, but the change is not big.
