摘要

Process for the production of process water methane and biogenic material The present invention relates to a process for the production of process water methane and biogenic material, such as occurs in the production of sugar and ethanol. a mixing / preliminary vessel (2) is supplied with process water and biomass, as well as optionally wash water and / or fresh water and / or substrate water, under slurry production, the slurry is adjusted to an appropriate ph value and temperature, the slurry thus adjusted is transferred to at least one bioreactor (8, 10), which has anaerobic methane bacteria and is left there for biogas production, the biogas developed in this way is extracted, and the biologically degraded liquid is discharged as well as a biogas unit (1) into it, with at least one mixing or preliminary container (2) for paste having a heat exchange system (7), and at least me- a biogas reactor (8, 10) disposed downstream with biogas producing bacteria, as well as the use of the biogas unit (1), for biogas production and accumulation of process and discharge water and by-products of sugar and ethanol.
