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.
The removal of SO2 and NO, 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.
