Abstract
A disposal apparatus according to a first aspect comprises an evaporation pipe communicating with a container for discharging vapor evaporated from raw sewage therein. A catalyst box accommodates a catalyst and communicates with the evaporation pipe. An ejector connects to the catalyst box for drawing air therefrom. A hot-air blower connects upstream to the catalyst box for heating flowing air, and an air supply unit supplies air to the ejector and the hot-air blower. A bypass pipe communicates between the ejector and the container. The disposal apparatus according to a second aspect comprises a heat-resistant airtight container for raw sewage, and an induction heating device disposed under the container. The heating device has a coil for generating a high-frequency electromagnetic wave to heat the container by induction. A rotatable stirrer and heat-holding balls are contained in the container. A stool communicates with the container through a valve mechanism.
