The invention relates to the production of biogas by means of multi-stage fermentation in a mono-tank. The device for biogas production by means of multi-stage fermentation in a single tank according to the invention is characterised in that the inside of the tank is provided with additional partitions, which are arranged in such a manner that the total volume of the tank is divided into at least two or more partial volumes, and partitioned tank sections are thus present, in which the various fermentation stages occur and which can be controlled according to the actual reaction progression. The device optionally has an ultrasonic module for treating a recirculated material from an advanced fermentation stage or from the device according to the invention. |
