| 摘 要： | 在自制的鼓泡反应器上对臭氧(O_3)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O_3对NO能够有效氧化,SO_2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.O_3]/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SO_2和NOx,脱硫效率几乎达到100%,在O_3]/NO]=1.1时,可获得84.2%的脱硝效率.

| Abstract: | The removal of SO_2 and NO_x by aqueous oxidation of O_3 was studied by self-designed bubbling reactor.The results show that NO can be oxidized efficiently by O_3 in liquid phase,while the existence of SO_2 has a negative impact on the removal of NO and pH value has a little impact. The NO removal efficiency is 89.6% at O_3]/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, SO_2 removal efficiency is nearly 100% and NOx removal efficiency is 84.2% at O_3]/NO]=1.1. SO_2 and NO_x can be removed effectively by aqueous oxidation of O_3 simultaneously. |
