Abstract: The invention relates to a system for reducing the hardness of a water body. According to the system, the acidic water body near a filter element anode is continuously extracted in the electrolytic process, the effect of acid-alkali separation can be achieved without internally disposing an ion exchange membrane, acid-alkali mixing generated by electrodes slows down, the alkaline atmosphere of a cathode chamber is kept, and a good environment is provided for generation of calcium carbonate seed crystals; and meanwhile, the acidic water body extracted near the anode of an electrochemical electrolysis unit can be used for regenerating ion exchange resin in an ion exchange column, so that resources are fully utilized.
