Abstract:
A self-forming dynamic membrane was introduced into anaerobic wastewater treatment for low strength municipal wastewater treatment. The feasibility and stability of the anaerobic self-forming dynamic membrane bioreactor (ASFDMBR) were investigated. The metabolic and interception ability and components of the selfforming dynamic membrane (SFDM) were also studied. The results showed that the ASFDMBR had good COD removal efficiency as high as 89.5%. SFDM had considerable metabolic ability with a COD removal efficiency of 7%, as well as good interception capacity. Sludge with a particle size range of 32μm~62μm was the major part of the SFDM. FTIR revealed that protein, polysaccharide and humic acid were the components of the SFDM.
