Systems and methods for the co-treatment of solid organic waste and sewage

摘要

Solid organic waste is processed into a suitable feedstock that can be mixed with sewage for anaerobic digestion. The processing of the solid organic waste initially transforms the solid organic waste into a uniform biomass. The uniform biomass is then subjected to hydrolysis and volatile acid fermentation to dissolve the soluble compounds leaving a small residual solid component. The liquid in which the soluble compounds are dissolved is then mixed with sewage in an anaerobic digester to produce biogas including methane. The residual solid component can be composted.
