Abstract

Two of municipal waste incinerators were selected as surveying facilities to research on the emission of dioxin and precusors. The sampling of flue gas and analysis was performed in the selected facilities. From the result, the emission patterns of dioxin and precusors, their relatership were examined. The toxic equivalency quantity(TEQ) of dioxin concentration was evaluated in two municipal waste incinerators. The 76.24% and 60.84% of total dioxin concentration in A and B incinerator were made up of the penta-, hexa- and hepta-chlorinated dibenzo-p-dioxin, respectively. Therefore, to reduce the dioxins in flue gas have to control the formation of furans. The chlorobenzenes and chlorophenols were analyzed in two incinerators. The 1,2,4,5-tetrachlorobenzene, penta-, and hexachlorobenzene are discharged and 2,4,6-trichlorophenol, 2,3,4,6-tetrachlorophenol and pentachlorophenol are discharged mainly in A and B municipal waste incinerators.
