摘要

The invention relates to a ternary sewage treatment method integrating microbial fuel cells with anaerobic acidification and forward osmosis membrane, and belongs to the technical field of sewage treatment. The method of the invention comprises the following steps:;Sewage is driven into the anaerobic acidification device for mixture with the NaOH solution. The mixed liquid enters into the MFC for converting the enriched organics to bioelectricity and then flows back to the anaerobic acidification device. A part of the mixed liquid passes through the MF membrane module to form effluent and enters into the sedimentation basin for phosphate removal and finally passes through activated carbon adsorption column, another part passes through the FO membrane module to form effluent and obtain high quality recycled water after the RO membrane processing. The method is a new coupled model of FO membrane and MFC and it provide a ternary combined technique integrating MFCs with anaerobic acidification and FO membrane. The change and accumulation of sewage to organic acids are achieved under anaerobic acid production and FO retention, the electricity generation performance of MFC is improved, and the reuse of reclaimed water is realized by separating of FO and RO membranes. Finally, the wastewater reuse and electricity generation are realized synchronously.
