Emissions of Poly chlorinated Dibenzo-p-dioxins and Dibenzofurans from Various Stationary Sources 2011-A-1022-AWMA

摘要

The mean total PCDD/F I-TEQ concentration of five different sources ranged from 0.00681 to 0.703 ng I-TEQ/Nm~3. Furthermore, in the indicatory PCDD/Fs analysis, the EAF, and secondary ALS have the same congeners, while CM, JP-A and JP-B have similar indicatory PCDD/Fs. The highest contribution of total PCDD/Fs is from fly ash (61.1-95.3%) for metallurgical facilities (EAF, secondary ALS), while 99.9% of the stack flue gas is from JP. Hence, fly ash from the metallurgical facilities should be carefully treated and JP incinerators need to be equipped with air pollution control devices (such as bag filters) to reduce PCDD/F emission.
