NOVELTY - Electrochemical appliance comprises a cathode (1), an anode (5), a guide wire (4), a resistor (3), and a stirring shaft (2). The stirring shaft has a spiral blade (8), a supporting rod (7), a sludge scraping plate (6), and a bracket (9). The cathode inside the water phase, the anode inside the sediment, and the resistor are connected in series through the guide wires, forming a loop. The resistor is arranged between the cathode and the anode. One end of the sediment is provided with a spiral blade that is around the stirring shaft.    USE - Electrochemical appliance used for deposited microorganism (claimed).    ADVANTAGE - The sediment contacted with electrode can be replaced by rotating the stirring shaft when the appliance has been used for a period of time, so that the efficiency of the appliance can be improved; and the repairing effect to the sediment can be increased. The appliance can obviously improve the mass transfer for organism inside the sediment of anode region. It has simple structure, less maintenance and building, and good economic benefit.    DETAILED DESCRIPTION - An electrochemical appliance comprises a cathode (1), an anode (5), a guide wire (4), a resistor (3), and a stirring shaft (2). The stirring shaft has a spiral blade (8), a supporting rod (7), and a sludge scraping plate (6). The cathode inside the water phase, the anode inside the sediment, and the resistor are connected in series through the guide wires, forming into a loop. The resistor is arranged between the cathode and the anode. The stirring shaft vertically crosses through the water phase and the sediment. One end of the sediment is provided with a spiral blade that is around the stirring shaft. The space unoccupied by the spiral blade is vertically provided with at least two supporting rods. The other end of the supporting rod is connected with the sludge scraping plate, so that the plate is axially parallel with the stirring shaft. The stirring shaft is located at the central position of the entire device by crossing through the cathode through the end located inside the water phase.
