By utilizing a narrow pulse power discharge

synergistic control of mercury and dioxins was studied by using 1

2

4-trichlorobenzene（TCB） as a dioxin analogue through a self-designed experimental system in order to control the emission of mercury and dioxin substances in waste incineration flue gas. The competitive effects of NO

SO

2

and HCl on the TCB removal by non-thermal plasma were discussed. In the three sour gas atmospheres

the oxidation of Hg

0

decreased by about 10%

the oxidation of Hg

0

by each gas component was complex

and the effect of NO on the degradation was relatively crucial. In the flue gas atmosphere of ‘acid gas + Hg

0

+ TCB’

the interaction between Hg

0

oxidation and TCB degradation was different. The contribution of various flue gas components to the results was complicated

but the overall experimental results show that the synergistic control effect

of the system can continue to improve. According to the reversion of generated products

·OH plays an important role in the synergistic control of the degradation of Hg

0

and TCB. This work should provide basic research data for flue gas synergetic control in incineration industry.
