ANAEROBIC DIGESTOR REACTOR AND METHODS FOR THE TREATMENT OF AQUEOUS ORGANIC WASTE STREAMS

摘要

An anaerobic digester reactor for anaerobically digesting aqueous organic waste or by-product streams comprising soluble and insoluble solids comprising: an elongate reactor vessel having a feedstock inlet at one end and a digestate outlet at the opposite end and whose longitudinal axis is disposed, in use, generally horizontally; at least one baffle extending partially across the vessel intermediate its ends to define a weir for reaction mass flowing horizontally along the vessel thereby dividing the vessel into at least two reaction zones; and a recirculation system for extracting at least a portion of the reaction mass from the vessel and reintroducing at least a portion of the extracted reaction mass into the vessel. Also provided is method for anaerobically digesting aqueous organic waste or by-product streams.
