S and CaO would obviously reduce PCDD/Fs formation, and the inhibition effect of S on HpCDD/Fs formation was more remarkable; however, CaO can inhibit the formation of HxCDD/Fs more evidently. The PCDFs are the main components of PCDD/Fs produced from MSW incineration in the experiments, and on account of the similar homologue profiles of PCDFs, it is believed that S and CaO couldn’t change the dominating route of PCDD/Fs formation which is so-called de novo synthesis. S and CaO may mainly consume chlorine sources or weaken the chlorination in the PCDD/Fs formation process to suppress the PCDFs formation during MSW incineration, but the inhibition mechanisms between S and CaO on the formation of PCDDs may be different. In addition, S and CaO may decompose some dioxins or precursors. |
