摘要：
Water softening device (1) includes water softening tank (3), neutralization tank (4), and electrolytic tank (9). Electrolytic tank (9) generates acidic electrolytic water for regenerating weakly acidic cation exchange resin (7) and alkaline electrolytic water for regenerating weakly basic anion exchange resin (8). Then, water softening device (1) includes an acidic electrolytic water circulation flow path that circulates the acidic electrolytic water through electrolytic tank (9), first discharge port (13), water softening tank (3), and first water intake port (12) in the stated order, and an alkaline electrolytic water circulation flow path that circulates the alkaline electrolytic water through electrolytic tank (9), second discharge port (17), neutralization tank (4), and second water intake port (16) in the stated order.
