PROCESS AND BIOGAS PLANT FOR PRODUCING BIOGAS FROM ORGANICALLY LOADED LIQUIDS

摘要

Process and biogas plant for producing biogas from organically loaded liquids, wherein a) the organically loaded liquids are aerated in a mixing vessel and subsequently transferred to a hydrolysis fixed-bed reactor, b) a hydrolysis is carried out in at least one hydrolysis fixed-bed reactor which contains random packings, the liquid is conducted repeatedly over the random packings by pumping off the liquid and feeding it back to the hydrolysis fixed-bed reactor via a recycle circuit, or pumping the liquid into further hydrolysis fixed-bed reactors, c) a substream of the organically loaded liquid is pumped from the recycle circuit into a methane fixed-bed reactor which contains random packings and fermented to form biogas.
