The Study of PCDD/Fs Distribution in a Medical Waste Incinerator

Although there were many studies focused on the PCDD/Fs emissions from different incinerators, but the emissions in a whole plant have seldom been reported. This paper investigated the distributions and congener profiles of the PCDD/Fs in the stack gas, fly ash, dust in the precipitator and slag from an whole medical waste incinerator. The result showed that 1) the PCDD/Fs of the dust in the precipitator had the highest level in all the samples. 2) 2,3,7,8-TCDD was the important characteristic factor in the TEQ values of most samples.
