| titleOfInvention | Stabilization treatment method for heavy metal-containing waste |
| abstract | (57) [Summary] [PROBLEMS] To provide a method for stabilizing waste which can prevent elution of heavy metals for a long time even when exposed to an acidic environment. SOLUTION: Magnesium hydroxide and / or magnesium oxide are added to heavy metal-containing waste having a pH value of less than 7, and the mixture is kneaded in the presence of water to adjust the pH value to 8 or more. Heavy metals to insoluble heavy metal hydroxides. At this time, since the pH value of magnesium hydroxide is about 10.3, the pH of the kneaded material is insolubilized by the amphoteric metals such as lead and zinc without adjusting the pH or adding a large amount of magnesium hydroxide. Can be kept in the range. |
