| titleOfInvention | Processing method for heavy metal-containing ash |
| abstract | In the elution prevention treatment of heavy metal-containing ash which has a problem of elution of chromium or even lead, cadmium and mercury, stable and efficient heavy metal treatment can be performed, and the safety in operation is high. Moreover, the processing method of heavy metal containing ash which does not have the problem of corrosion with respect to liquid-contact parts, such as a chemical injection piping and a kneader, is provided. A method for treating heavy metal-containing ash comprising adding and mixing erythorbic acid and / or a salt thereof to heavy metal-containing ash having a high chromium content. A method for treating heavy metal-containing ash, wherein erythorbic acid and / or a salt thereof and a heavy metal fixing agent are added to and mixed with heavy metal-containing ash containing a large amount of chromium, lead, cadmium and mercury. As the heavy metal fixing agent, a dithiocarbamic acid chelating agent is preferable. [Selection figure] None |
