PROBLEM TO BE SOLVED: To provide a method of processing phosphorus-containing waste oil, configured to obtain calcium agglomerate (a calcium phosphate group crystalline material) in a short time and to easily increase a recovery rate of P in the calcium agglomerate or an incinerated object thereof.SOLUTION: In the method of processing phosphorus (P)-containing waste oil, Ca is added to P by an amount that is equal to or more than an atomic ratio so as to generate a calcium phosphate-based crystalline material, after NaOH-containing solution is added by an amount 0.15 to 2.0 times that of the waste oil, to be emulsified. The above material is emulsified again and left, to generate agglomerate (precipitate), so as to incinerate (heat) the agglomerate. |
