摘要

Polychlorinated dibenzo-p-dioxins(PCDDs) and polychlorinated dibenzofurans(PCDFs) in fly ash from an 150T/D coal and municipal solid waste (MSW) fluidized bed combustor were detected by HRGC/HRMS. The amount of PCDDs/PCDFs in fly ash was 10260.14ng/kg, and the I-TEQ value was 80.34ng/kg and in flue gas the total value was 4.214ng/m~3, I-TEQ value was 0.1126ng/m~3, separately. The levels of PCDDs/PCDFs detected were less than what has been observed in conventional municipal solid waste incinerator fly ash samples. Co-firing coal in MSW incineration can inhabit PCDDs/PCDFs formation. he sulfur in coal and less content of heavy metals (Copper, Nicker) in fly ash can explain the lesser PCDDs/PCDFs emission.
