NOVELTY - Synchronized purification of sewage and power generation comprises filling tanks with conductive filler, filling with non-conductive filler, planting wetland plants, burying collectors, connecting wires, sealing, connecting wires to conductive filler, inoculating activated sludge, domesticating, pumping wastewater, treating, and driving load. Synchronized purification of sewage and power generation device includes artificial wetland downstream tank (1), upstream tank (2), downstream tank conductive filler layer (anode region) (7) and upstream tank conductive filler layer (cathode region) (13).    USE - Method for synchronized purifying sewage and generating power (claimed).    ADVANTAGE - The method is simple and easy.    DETAILED DESCRIPTION - Synchronized purification of sewage and power generation comprises filling tanks with conductive filler, filling with non-conductive filler, planting wetland plants, burying collectors, connecting wires, sealing, connecting wires to conductive filler, inoculating activated sludge, domesticating for 10-14 days, pumping wastewater, treating, and driving load. Synchronized purification of sewage and power generation device includes artificial wetland downstream tank (1), upstream tank (2), downstream tank conductive filler layer (anode region) (7), upstream tank conductive filler layer (cathode region) (13), wetland plants, wetland plant root system (10), anode current collector, lead, cathode collector electrode, sealing cover, sealing plug and load. Upstream and downstream tanks are filled with conductive material to heights of 18-22 cm and 28-32 cm, respectively. Upstream and downstream tanks are filled with non-conductive material to heights of 8-12 cm and 13-17 cm, respectively. Wetland plant is Lythrum salicaria, wild rice, Canna, Acorus calamus, Spartina, Arundinella hirta, bulrush, ditch reed, elephant grass, silver grass and/or cattail.
