Abstract

PURPOSE: To lower a melting point efficiently, while avoiding the increase in a processing cost, bu mixing sludge from a water treatment process with incinerated waste matter ash different from said sludge and iron oxide or a substance mainly composed of iron oxide, and melting the mixture.
CONSTITUTION: Dewatered cake obtained by dewatering tap water sludge is fed to a melting oven in a state mixed with incinerated sewage sludge ash and iron oxide or a substance mainly composed of iron oxide, and melted therein. The substance mainly composed of iron oxide may be scrap or the like obtained by shot-peening a product or descaling in ship building, piping or the like. The incinerated sewage sludge ash may be ash separated and recovered from incinerated dewatered cake obtained by treating sewage with active sludge and dewatering the resulting sludge with a cyclone or the like.
