To provide a drain cleaning device for increasing electric conductivity of drain to facilitate a flow of an electric current in the case that the electric conductivity of drain is low, and enhancing oil/water separation performance of the drain.
This drain cleaning device is provided with an electrolytic separation tank having at least a pair of electrodes in the inside and separating the drain turbid with oil and water to the oil and water, a sub-tank for storing the drain, and a piping part for connecting these. This device is provided with a heating means for heating at least any drain liquid among the drain liquids in the insides of the electrolytic separation tank, the sub-tank or the piping from the sub-tank to the electrolytic separation tank.
