Industrial circulating water treatment device

The invention discloses an industrial circulating water treatment device. The industrial circulating water treatment device comprises a first shell, wherein a reaction chamber capable of being communicated with industrial circulating water is arranged in the first shell; a cathode plate; an anode plate; wherein the cathode plate and the anode plate are both arranged in the reaction chamber, and the cathode plate and the anode plate can be conducted with a cathode and an anode of the direct-current power supply respectively, so that an electrolytic reaction occurs between the cathode plate and the anode plate. When the cathode plate and the anode plate are respectively conducted with the cathode and the anode of the direct-current power supply, electrolytic reaction occurs between the cathode plate and the anode plate, so that the scaling phenomenon is reduced, the pipeline blockage phenomenon of the heat exchanger is reduced, the normal production is ensured while the heat exchange efficiency of the heat exch
