Thermal Decomposition and Stabilization of the Lagoon Sludge Solid Waste after Dissolution with Water
Abstract
Thermal decomposition and stabilization characteristics of the solid cake after the dissolution of nitrate of the lagoon sludge was investigated. Most of the nitrates were dissolved in the water and removed to the filtrate, but small amount of nitrates, calcium carbonate and uranium were remained in the solid cake. The solid cake was thermally decomposed in the muffle furnace at for 5 hours. Uranium, which is in the lagoon 1, was stabilized with decomposition to form. For the lagoon 2, it is confirmed that CaO, which was created by thermal decomposition of the and , was transferred to in the air with water. Because it is known that is stable material, further additives did not need to the stabilization of the thermal decomposition of the lagoons.
