Anaerobic fermentation reactor with packing material

摘要

1. Process for the biological anaerobic treatment of liquid effluents containing concentrated organic pollutants, in which fermentation is carried out through an immersed bed with a low density lining, free or floating, characterized in that the elements of the lining have a proper density higher than that of the liquid, although at the most equal to 1.5, but a vacuum percentage of free passage rate higher than 90% and a specific useful surface greater than 100 m**2 /m**3 , so that they are caused to float by the fermentation sludges.
