PURPOSE:To continuously treat waste, by preventing intermediate product from solidifying by burning or thermally decomposing the waste containing ion exchange resin under the coexistence of acid constituent such as phosphoric acid and/or acidified constituent such as hydrogen peroxide solution. CONSTITUTION:Waste containing ion exchange resin is dehydrated down to 50% in a dehydrating tank 3, is fed into a feed tank 5 by a rating feeder 4, and is fed into an incinerator 8 to be burned by a rating feeder 7. A predetermined quantity of additive is fed into the waste containing ion exchange resin flowing through the rating feeder 7, from an additive feed tank 6, which is provided at the outlet of a feed tank 5 and is connected to the rating feeder 7. As for the kind of additives, phosphoric acid is recommendable as an acid constituent from the viewpoint of after-treatment and easiness of handling. As for an acidified constituent, hydrogen peroxide water is favorable. As for the temperature during combustion, the range of 650-750 deg.C is favorable from the points of combustion efficiency and an economic factor. |
