摘要： PROBLEM TO BE SOLVED: To provide a treating method for incineration ash capable of recycling granular materials in the incineration ash by efficiently making the granular materials non-polluting, and to provide aging facilities capable of efficiently and stably preventing the elution of heavy metals. SOLUTION: The incineration ash is fed into frictional crushing treatment devices 30 and 50 where the granular materials are made into finer grains by adding water thereto and acting the force to rub the granular materials against each other thereon and the fine grain components containing hazardous materials, such as heavy metals and dioxins, at high ratios are separated from the surface of the granular materials and thereafter the fine-grain incombustibles in the incineration ash are extracted by a vibration screen 60. These incombustibles are supplied to the aging facilities 80 where carbon dioxide is supplied thereto while a proper volume of water is added to the granular materials to bring the granular materials into contact with the carbon dioxide.

摘要： PROBLEM TO BE SOLVED: To scale down an ash melting equipment and to reduce the treating cost by reducing the volume of the incineration ash to be melted and solidified and to simplify the equipment for reducing the volume of the incineration ash. SOLUTION: A fitting force is exerted on a granular body in the incineration ash by using two milling devices 30 and 50 to finely granulate the granular body. The fine grain containing a large amount of a harmful material such as heavy metal and dioxin is separated from the finely granulated granular body in process water, then the unburned coarse grain and unburned fine grain in the ash are respectively made harmless and extracted by using vibrating screens 40 and 60, a dehydrated cake is formed from a slurry containing the fine grain of the remaining harmful material, and the dehydrated cake is dried in a drying furnace 81, charged into a melting furnace 82, melted and solidified.

SOLUTION: The incineration ash to be treated is previously agitated in water by a pretreating device 28 to uniformly disperse the granular materials in the incineration ash and thereafter the granular materials are subjected to grinding treatment by using grinding treatment devices 30 and 50 and vibration sieves 40 and 60 and, simultaneously, the fine grain components containing hazardous materials, such as heavy metals and dioxin, at high ratios are separated into the treating water, by which the coarse grain incombustibles and fine grain incombustibles in the incineration ash are respectively made non-polluting and are extracted. Hydrated cake is produced from the fine grain components containing the many hazardous materials and only the dydrated case is melted and solidified.

摘要： PROBLEM TO BE SOLVED: To provide a method for treating a contaminant-adhered granular body by which the contaminant is efficiently separated and removed from the granular body adhered with contaminants such as contaminated soil and incineration ash. SOLUTION: A granular body contaminant-adhered is introduced into a primary pulverizer 11 and a secondary pulverizer 12, disintegrated and deflocculated to remove a contaminant depositing on the surface of the granular body. Subsequently, a large-diameter granular body freed from the contaminant is separated by liq. cyclones 30 and 32, and the fine grains contg. the contaminant are conducted to a centrifugal separator 42 and separated.
