| titleOfInvention | Method for treating phosphorus-containing substances |
| abstract | (57) [Summary] [PROBLEMS] In a work process of heating sewage sludge to make incineration ash, at least one of calcium oxide and calcium hydroxide and calcium fluoride are added to phosphorus-containing material and heated. By providing phosphorus as fluorapatite, even if the obtained incinerated ash is used as a raw material for a cement product, a method for treating a phosphorus-containing substance that does not dissolve phosphorus from the product and therefore does not have a risk of delaying coagulation is provided. I do. A phosphorus-containing substance such as sewage sludge contains at least one of calcium oxide and calcium hydroxide. The seed and calcium fluoride are added and heated, so that phosphorus is generated as fluorapatite and treated. |
