Method and apparatus for mixing of fluid biomass in a bioreactor, especially in the presence of mesophilic and/or thermophilic micro-organisms obtaining the methane gas simultaneously

摘要

The manner according to the invention consists in: the mixing occurs in two successive phases: the rising phase - during which the biomass is led to the upper tank (1) through the ascent pipe (2) into the upper tank (1) and the recirculation phase during which the biomass swelled before is introduced into the upper part of the bioreactor (5). The apparatus according to the invention has the upper tank (1), inside which the upper ending of the ascent pipe (2) is placed and out of which at least one recirculating pipe (3) closed return is led out.
