Bioreactor and its use, process for the preparation of an organic nutrient solution, organic nutrient solution, substrate material and its use for the cultivation of plants

摘要

The invention relates to a bioreactor (1, 2, 3) and its use for the conversion of organic residues and / or waste into an organic nutrient solution with a proportion of at least 10% plant-available mineralized nitrogen based on the total nitrogen content of the nutrient solution, with a reaction vessel ( 5), wherein the reaction vessel (5) has a feed line (6), via which a suspension (4) in the reaction vessel (5) can be introduced, and wherein the reaction vessel (5) has a discharge line (7), via which the suspension (4) from the reaction vessel (5) can be derived, and with a ventilation device (8) for venting the suspension (4) and / or within the reaction container (5) arranged support member (10), wherein the carrier element (10) at least one inner and an outer settlement surface (11) on which ammonifying and / or nitrifying bacteria ansied in a biofilm (12) can.
