Abstract: 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.

Abstract: This invention describes a high-power, high-energy oxidant (catholyte) chemistry based on dichromate (CrVI as Cr2O72−) for use with a variety of fuels (anolytes) in redox flow batteries (RFBs, also known as reversible fuel cells), which reversibly store electricity as chemical energy. The reduction (discharge) of Cr2O72− to Cr3+ is natively irreversible at all investigated solid-state electrocatalysts, which has historically limited the employment of Cr2O72− to primary (non-rechargeable) cells, such as Grenet cells. The described invention overcomes this limitation by using a reversible redox couple, hereafter electron mediator, to heterogeneously donate electrons to the cathode electrocatalyst and homogeneously accept electrons from Cr3+ to regenerate Cr2O72−. RFBs employing this energy- and power-dense chemistry are suitable for low-cost energy storage applications, ranging from grid-level storage of renewable electricity to consumer electronics.
