| 中文摘要 |
| 在自制的鼓泡反应器上对臭氧（O3）液相氧化分别脱硫脱硝技术进行了实验研究.结果表明，液相中O3对NO能够有效氧化，SO2的存在对NO的脱除具有一定的负面影响，而pH值对NO的脱除率影响较小.［O3］/［NO］=1.1时，NO脱除率可达到89.6%.pH在3～11范围内，NO脱除率达80%以上.温度在20～65℃范围内，NO脱除率不发生明显变化.结合尾部洗涤装置后，可有效脱除SO2和NOx，脱硫效率几乎达到100%，在［O3］/［NO］=1.1时，可获得84.2%的脱硝效率. |
| 英文摘要 |
| 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℃, NO removal efficiency has no change. Combining with wet scrubbing tower, SO2 removal efficiency is nearly 100% and NOx removal efficiency is 84.2% at ［O3］/［NO］=1.1. SO2 and NOx can be removed effectively by aqueous oxidation of O3 simultaneously. |
