To provide a fermentation raw material capable of allowing aerobic fermentation to quickly proceed and promoting an effective use of resources, by a simple operation alone of adding a prescribed amount of a specific material to sewage sludge.SOLUTION: The sewage sludge fermentation raw material according to the present invention for use in aerobic fermentation of sludge, includes sewage sludge and coffee grounds, in which the coffee grounds are included therein in an amount of 52 pts.mass or more and 200 pts.mass or less relative to 100 pts.mass of the sewage sludge. The present invention also provides a sewage sludge processing method that uses a sewage sludge fermentation raw material including 52 pts.mass or more and 200 pts.mass or less of coffee grounds relative to 100 pts.mass of the sewage sludge.SELECTED DRAWING: Figure 1 【課題】下水汚泥に特定の材料を所定量添加するという簡便な操作のみで、好気発酵を速やかに進行させることができ、資源の有効利用に繋げることができる発酵原料を提供すること。【解決手段】本発明の下水汚泥発酵原料は、下水汚泥と、コーヒー粕とを含み、該コーヒー粕を、該下水汚泥１００質量部に対して５２質量部以上２００質量部以下含む好気発酵処理用のものである。また本発明は、下水汚泥１００質量部に対して、コーヒー粕を５２質量部以上２００質量部以下含む下水汚泥発酵原料を用いる、下水汚泥の処理方法も提供する。【選択図】図１
