| titleOfInvention | Treatment method of acidic molten fly ash |
| abstract | (57) [Summary] [Object] The present invention provides a method for treating acidic molten fly ash, which is capable of economically and sufficiently preventing the elution of heavy metals contained in the acidic molten fly ash. [Structure] The present invention is a method for treating acidic molten fly ash generated when melting waste or its incineration residue, wherein pH is adjusted to 8.5 or more by adding slaked lime to the acidic molten fly ash. 0.1 to 10 parts by weight of calcium polysulfide is added to 100 parts by weight of acidic molten fly ash, and mineral acid is further added to adjust the pH to 8. After adjusting to 5 to 10.0, 10 to 35 parts by weight of water is added to 100 parts by weight of acidic molten fly ash and kneading is performed. |
