| 摘要 |
The invention relates to a method for operating a biogas system (1) according to the principle of dry fermentation with a plurality of biogas fermenters (2a-2d) that are run in batch mode. At least one of the biogas fermenters (2a-2d) has just been loaded with fresh biomass and the other biogas fermenter or fermenters (2a-2d) are in the state of producing more highly concentrated biogas. The method provides for closure of the at least one biogas fermenter (2a-2d) loaded with fresh biomass and connection of the at least one biogas fermenter (2a-2d) loaded with fresh biomass to at least one of the other biogas fermenters (2a-2d) producing biogas. In addition, there is a return of the biogas mixture from the at least one freshly loaded biogas fermenter (2a-2d) to at least one of the other biogas fermenters (2a-2d) producing biogas. After expiration of a defined time duration, the return of the biogas mixture from the freshly loaded biogas fermenter (2a-2d) is stopped. The invention also relates to a biogas system (1) which is suitable for operation in accordance with the method of the invention. |
