Description

Technical Field

[0001] The utility model relates to the technical field of electrochemistry, in particular to an electrochemical water treatment device. Background Art

[0002] Existing water treatment equipment needs to reduce the alkalinity of the water body by adding acid. Specifically, acid is generated at the anode and scale is formed at the cathode, thereby reducing the HP value of the system water. The scale on the cathode surface needs to be removed. The existing method is to clean it manually, but the efficiency is very low. Another common method is the polarity reversal method, which reverses the original positive and negative poles, but polarity reversal will reduce the life of the electrode and the efficiency is also relatively low.

[0003] In addition, existing water treatment equipment simply adds acid or produces acid at the anode, which will accelerate the consumption of consumables and increase the treatment cost. In view of the above-mentioned situations, we have proposed an electrochemical water treatment equipment. Utility Model Content
