Abstract

A raw sewage disposal apparatus for evaporating and drying raw sewage by heating. An evaporation container has a closed bottom portion and an opened upper portion for containing raw sewage thereon. A rotary holding structure holds an upper end of the evaporation container so as to permit horizontal rotation thereof. A covering supports the rotary holding structure and closes the opened upper portion of the evaporation container from the atmosphere. A frame capable of hanging the evaporation container supports the covering substantially horizontally. A driving device is provided for rotating the evaporation container, and an electromagnetic heating means is disposed close to a lower surface of the evaporation container and generates a high-frequency electromagnetic wave which is supplied to the evaporation container.
