Abstract: PURPOSE: Provided is a bio-electric cell that organic material of wastewater is used as fuel and microorganisms of activated sludge is used as catalyst. Wastewater and activated sludge are filled around a cathode. At the cathode, microorganisms of wastewater or activated sludge are cultivated in an anaerobic condition, so only microorganisms, which use the cathode as electron acceptor, are cultivated selectively. Generally, microorganisms are covered with lipid film being nonconductive, so electron exchange is not occurred directly between microorganisms and electrode. Therefore, phosphate buffer solution is used as an electronic conductor in the bio-electric cell. Consequently, electrochemically activated microorganisms oxidize organic material of wastewater and electrons are produced by oxidation of organic material. The electrons are discharged to the exterior of cell of the microorganisms and are transferred to the cathode. Then, electric current is generated and wastewater is purified by oxidation of organic material. CONSTITUTION: The bio-electric cell is comprising by follow parts: graphite felts used as cathode and anode; a cation exchange resin to minimize resistance of the bio-electric cell; phosphate buffer solution for electronic conduction; an anode being aerobic condition; a cathode being anaerobic condition.
