PURPOSE: To suppress the contamination of the titled cntinuous fermentation system with various germs, and to enable the continuous operation stably for a long period, by accumulating and discharging the produced and precipitated floc from the reaction tank through the part placed in the tank.
CONSTITUTION: A precipitate accumulation part 3 composed of inclined plates is attached to the bottom of the reactor (the sign 1 is the feeding port of the raw material and 5 is exhaust port of the produced gas) containing a number of vertical membranes 2 of immobilized microorganisms. The precipitating suspensoid (floc) produced in the tank is accumulated in the part 3, and the fermentation is continued while discharging the accumulated floc through the discharging line 4.
