Description

technical field [0001] The invention belongs to the technical field of electrochemical water treatment, and relates to a high-efficiency electrode for treating industrial circulating cooling water and a preparation method thereof. Background technique [0002] The circulating water system is one of the indispensable energy media for the production of metallurgy, energy and chemical enterprises. With the increase of the concentration ratio of circulating cooling water, the phenomenon of microbial reproduction, fouling and corrosion will appear in the system. In order to prevent the water quality from deteriorating indefinitely, on the one hand, part of the concentrated water must be discharged to supplement the clean water, and on the other hand, sterilization, anti-scaling and anti-corrosion treatment must be carried out. At present, the chemical agent method is generally used to control the quality of circulating cooling water. This method has problems such as high chemica...
