<p>PROBLEM TO BE SOLVED: To provide a facility and a method for treating industrial waste at a low cost in which oceanic waste can be treated on a vessel and recovered as resources without generating dioxine. SOLUTION: FRP waste is carbonized and thrown into a melting furnace together with cokes and combusted. Substances discharged as molten slag are separated and collected as metal oxides which are then blown into the combustion chamber in the furnace and combusted completely. Unburnt hydrocarbon is oxidized and decomposed and precursors of dioxins, e.g. organic chloride compounds, are removed. On the other hand, shells are calcined in a calcination furnace using combustion exhaust gas to produce slaked lime. At the same time, hydrogen chloride being generated in the incinerator is reduced in order to protect a smoke exhauster against corrosion and collected by a dust collector while being separated before filtered clean gas is discharged into the atmosphere. Furthermore, environmental protection products, e.g. a soil improving agent or a water quality purifier, are produced from treated slag or slaked lime on a vessel for treating industrial waste.</p> |
