| 摘要 |
The invention relates to a method and a device for the treatment of organic residual products occurring, for example, in biogas systems, wherein a digestate develops from the organic residual products as an intermediate product during biogas regeneration in a fermenter, the digestate being subjected to a mechanical treatment comprising at least one thickening step. Subsequent to the mechanical treatment, a first part of the liquid digestate passes through a concentration process for the production of top dress, and a second part of the thickened digestate passes through a drying process for the production of bottom dress, wherein a mass flow of the top-dress concentrate is fed to the partial flow of the bottom-dress production such that the bottom dress is fortified with usable agents. Due to this fortification, the digestate can either be gasified for energy generation, or utilized as an organic agricultural fertilizer. |
