The removal of SO2 and NOx by aqueous oxidation of O3 was studied by self-designed bubbling reactor. The results show that NO can be oxidized efficiently by O3 in liquid phase, while the existence of SO2 has a negative impact on the removal of NO and pH value has a little impact. The NO removal efficiency is 89.6% at [O3]/[NO] = 1.1. When the rang of pH value is in 3-11, NO removal efficiency can be achieved over 80%. At 20-65 degrees C, NO removal efficiency has no change. Combining with wet scrubbing tower, SO2 removal efficiency is nearly 100% and NO2 removal efficiency is 84.2% at [O3]/[NO] = 1.1. SO2 and NOx can be removed effectively by aqueous oxidation of O3 simultaneously.
采用自行设计的鼓泡反应器研究了O₃水相氧化法去除SO₂和NOₓ的效果。结果表明，NO在液相中能被O₃有效氧化，而SO₂的存在对NO的去除有负面影响，pH值的影响较小。当[O₃]/[NO]=1.1时，NO去除率为89.6%。当pH值范围为3 - 11时，NO去除率可达到80%以上。在20 - 65℃时，NO去除率无变化。与湿式洗涤塔相结合，当[O₃]/[NO]=1.1时，SO₂去除率近100%，NO₂去除率为84.2%。O₃水相氧化法可同时有效去除SO₂和NOₓ。
