Abstract

PURPOSE: To compact the titled device and to reduce the running cost by holding the inside of the vacuum drier at the specified temp. and introducing anaerobic bacteria thereinto.
CONSTITUTION: Night soil is collected in a storage tank 1 and anaerobic bacteria are introduced thereinto and stirred. Night soil is fed to a vacuum drier 3 by a transfer pump 2. Solenoid valves 15, 16 are actuated and controlled so that the inside of the vacuum drier 3 is held at 50W70°C. Gaseous methane produced by the fermentation of night soil is passed through a desulfurizer 11 and stored in a gas holder 10. When water content of night soil incorporated in the vacuum drier 3 reaches 30W40%, degree of vacuum is reduced and night soil is allowed to fall to a two-step drier 4. Herein it is reheated by the exhaust B of a boiler and steam A and furthermore water content is reduced and thereby the burden of sewage treatment can be reduced.
