<p>In this process for biochemical substance conversion, in particular for treatment of waste water or sludge, the substrate for a digestion process is fed to a treatment stage. This treatment stage has at least two reactors and a substrate return line, and the substrate is subjected to an elevated temperature. For specific substrate stabilisation in each of the two reactors, the substrate in the first reactor is treated at about 45 DEG C to 65 DEG C, preferably about 55 DEG C. In the second reactor the substrate is treated at about 35 DEG C. Moreover, the substrate can be fed back from each of the reactors through assigned individual return lines in individual substrate part quantities so that a separate treatment variation can be carried out.</p> |
