NOVELTY - A waste treatment type electricity generation system has a methane fermentation tank (2), a dehydration unit (3), a drying unit (4) and a gasifier (5) which forms a heating gas (24). Methane (18) formed by the tank and heating gas formed by the gasifier are used as the fuel for a fuel cell. The high temperature water vapor produced by an electrical power generating device (1) is introduced to the gasifier.    USE - In hotel, departmental store, city refuse type organic waste ejection enterprise (all claimed), flats and factory.    ADVANTAGE - The waste treatment type electricity generation system is compact, saves space and reduces scrap amount of resources. Since methane and heating gas which are formed from the organic substance are used as fuel, the system has improved energy efficiency and saves resources. Environmental pollution by toxic substances, and reclaimed ground problems are eliminated. Energy recycling is possible.    DETAILED DESCRIPTION - A waste treatment type electricity generation system has a methane fermentation tank (2) which carries out anaerobic fermentation of the organic waste (17), a dehydration unit (3) to dehydrate the digested sludge, a drying unit (4) to adjust the water content of the dehydrated sludge, and a gasifier (5) which forms a low molecule dry sludge with high temperature water vapor (12), and also a heating gas (24). Methane (18) formed by the tank and heating gas formed by the gasifier are used as the fuel for a fuel cell. The high temperature water vapor produced by an electrical power generating device (1) is introduced to the gasifier. The electrical power generating device has a fuel cell which carries out the electrical generation of the valuable material collected from the organic waste of the sludge.
