Abstract
PURPOSE: To make it easy to handle disposal treatment or the like by a method wherein an org. substance containing sludge added with Ca, Mg is subjected to dehydration treatment and after incinerated and molded, reacted with gaseous CO2 to solidify said sludge in an energy saving manner at low cost.
CONSTITUTION: To the sludge contg. org. substances, a calcium component such as slaked lime or the like and a Mg component such as light burnt magnesia or the like or a mixture thereof are added preliminarily as a drying aid in an amount of about 0.1W100% and said sludge is treated by dehydration. This dehydrated cake is incinerated at 600W1,000°C to activate Ca, Mg components. The obtained fine pulverous incineration residue is molded to an appropriate size and reacted with a gaseous CO2 of 100W0.03% concn. to be solidified. This added dehydrating aid has dehydrating capacity as well as functions effective as a solidifying agent of incineration residue. By this treating method, harmful substances such as heavy metals or the like are certainly sealed and the disposal treatment can be carried out efficiently at low cost.
