  • 摘要: 近年来我国城市固体废物产生量逐年增加，水泥窑协同处置废物技术发展迅速.本研究选择1台规模为3200 t·d-1的协同处置固废水泥窑，对烟气中汞等非常规污染物排放浓度进行现场测试，研究汞等非常规污染物分析与排放.研究表明，协同处置废物水泥窑窑尾烟气出口Hg0占比79%，Hg2+占比21%左右，烟气中Tl+Cd+Pb+As和Be+Cr+Sn+Sb+Cu+Co+Mn+Ni+V平均浓度为32.12 μg·m-3和10.54 μg·m-3均低于我国协同处置固体废物水泥窑窑尾允许排放限值1.0 mg·m-3和0.5 mg·m-3，窑尾烟气中HF平均0.21 mg·m-3，HCl平均4.49 mg·m-3，PM2.5窑尾和窑头袋式除尘后出口烟气浓度，窑尾排放浓度较窑头高.
    Abstract: With the increase of municipal solid waste (MSW) in recent years, the disposal techniques for co-process of MSW in cement kilns is improved rapidly. A co-process of MSW in the cement kiln with the capacity of 3200 t·d-1 was selected, and emission of heavy metals was analyzed. The experiment results showed that the concentration of Hg0 accounted for 79% of gaseous mercury discharged from Cyclone preheater, while Hg2 + accounted for about 21%. The total concentrations of Tl + Cd + Pb + As and Be + Cr + Sn + Sb + Cu + Co + Mn + Ni + V were 32.12 μg·m-3 and 10.54 μg·m-3, which are lower than the allowable limits of 1.0 mg·m-3 and 0.5 mg·m-3 of the emission standard in China. The average concentrations of HF and HCl reached 0.21 mg·m-3 and 4.49 mg·m-3. The emission concentrations of PM2.5 discharged from the Cyclone preheater was greater than that from the cooler.
