采用UV/H2O2体系进行烟气脱硫脱硝的实验研究

为寻求一种高效的烟气多污染物脱除技术，采用UV/H2O2体系进行烟气脱硫脱硝实验研究。在自制的鼓泡反应器上考察模拟烟气成分、H2O2溶液浓度和催化剂等影响因素对脱硫脱硝效率的影响，得出了最佳实验条件。当pH值保持在3.3左右，氧气体积浓度大于6%，溶液温度在45℃以下，加入金属催化离子时，SO2及NOx的脱除效率可达到95%以上。对实验结果进行了讨论和分析，认为该技术有望用于现有传统湿式脱硫技术的改造，使其具有同时脱硫脱硝功能。

Experimental Study on Desulfurization and Denitrification Using UV/H2O2 System

The influencing factors and reaction mechanism of desulfurization and denitrification by UV/H2O2 were studied to find an efficient method for multi-pollutants control. Effects of the compositions of simulating flue gas, concentration of H2O2 and catalyst etc. on the efficiency of desulfurization and denitrification were studied by self-designed bubbling reactor, and the optimum conditions were achieved. The removal efficiencies of SO2 and NOx can both be above 95%, which are gained under pH value about 3.3, more than 6% of O2 content, less than 45 ℃ of temperature and addition of metal ions as catalyst. The experimental results were discussed and analyzed, it is regarded the technology as a method to rebuild for traditional wet desulfurization unit, make it have the function of simultaneous desulfurization and denitrification.
