无机离子对UV/H2O2氧化脱除燃煤烟气NO影响研究
Study on Effects of Inorganic Ions on Removal of NO From Coal-fired Flue Gas by UV/H2O2 Oxidation
在新型光化学反应器上，考察了实际燃煤烟气和天然水体中常见的无机阴离子和金属阳离子对UV/H2O2氧化脱除燃煤烟气中NO的影响及规律。结果显示: NO3-和Cl-对NO脱除有轻微的抑制作用，SO42-﹑HCO3-和CO32-对NO脱除有促进作用。随着Cu2+和Mn2+浓度的增加，NO脱除效率增加，但随着Fe2+和Fe3+浓度的增加，NO脱除效率呈现先增加后下降的趋势。
The effects and law of common inorganic anions and metal cations in actual coal-fired flue gas and natural waters on removal of NO from coal-fired flue gas by UV/H2O2 oxidation was investigated in a novel photochemical reactor. The results show that both NO3- and Cl- have a slight inhibition role for NO removal. All of SO42-, HCO3- and CO32- have a promoting role for NO removal. With the increase of Cu2+ or Mn2+ concentration, NO removal efficiency increases. With the increase of Fe2+ or Fe3+ concentration, NO removal efficiency first increases and then decreases.
