| 摘 要： | 通过对装有选择性催化还原(SCR)脱硝装置的燃煤锅炉排放烟气中的多环芳烃(PAHs)进行测试,分析比较了工业锅炉排放的PAHs经过SCR脱硝装置前后的排放特性变化.实验结果表明,烟气催化脱硝装置促进了PAHs含量的增加,特别是低环多环芳烃含量的增加,并提高了其毒性当量,但对PAHs在气相与颗粒相的分布影响不大.

| Abstract: | The polycyclic aromatic hydrocarbons (PAHs) in flue gas emitted from a coal-fired power plant equipped with selective catalytic reduction (SCR) de-NOx device were determined. The concentrations and distributions of phase and type of PAHs in the flue gas at the outlet and inlet of the SCR device were compared. The results show that the SCR de-NOx device leads to the increase of concentrations and toxic equivalent of PAHs, especially the low rings of PAHs in the flue gas. However, the device has no significant influence on the PAHs partition between particle and the gas phase. |
