PROBLEM TO BE SOLVED: To provide an incineration ash treatment method by which vanadium in incineration ash, adversely affecting cement production equipment can be easily removed when using incineration ash, and to provide a production method of cement using the incineration ash treated by the treatment method as a raw material.SOLUTION: There is provided the incineration ash treatment method, the incineration ash to be used for cement production. The method includes a water washing step of applying a water washing treatment to the incineration ash and kiln dust by adding the incineration ash and the kiln dust separately or at the same time into water or an aqueous solution, and a filtration step after the water washing treatment in this order. In the method, the addition amount of the kiln dust is set to be 3 to 35 mass% based on the total addition amount of the incineration ash and the kilt dust. There is also provided the production method of cement using the incineration ash treated by the incineration ash treatment method as a part of raw materials. |
