After being electrified, a strong alkaline environment is formed in the cathode area to generate OH - , and OH - The HCO3 -Convert to CO3 2- Under the action of the micro-vortex flow field, Ca 2+ CaCO3 is generated near the cathode and deposited on the surface of the cathode; a strong acid environment is formed in the anode area and Cl - is converted into Cl2, which is further converted into HClO to play a sterilization role, while consuming CO3 2- Further reduces the carbonate hardness of circulating water, and the water produced by the hardness removal module is acidic with a pH of 6-7.

[0046] The present application adopts low-voltage micro-current reverse-pole descaling, and during the reverse-pole process, the electrode is flushed by using a circulating flushing water pump to improve the descaling efficiency.
