PROBLEM TO BE SOLVED: To resolve such a problem that a storage anaerobic fermentation tank is disposed side by side with a continuous anaerobic fermentation tank, therefore, pipes are required for transport of liquid slurry between a pump and the fermentation tanks, and consequently the construction cost and installation area increases when a digestion liquid storage tank is utilized as the storage anaerobic fermentation tank in an ordinary anaerobic fermentation fcility which is installed outdoors and is composed of the continuous anaerobic fermentation tank, its auxiliary facilities and the digestion liquid tank. SOLUTION: The composite anaerobic fermentation facility is constituted in such a manner that the continuous anaerobic fermentation tank is disposed in the storage anaerobic fermentation tank and an overflow system from the continuous anaerobic fermentation tank is used for the transport of liquid from the continuous anaerobic fermentation tank to the storage anaerobic fermentation tank.
