The electromagnetic control valve on the desalted water inlet pipe 5 is opened and closed when the target liquid level is reached. This control is the second-stage dilution. If the added liquid level exceeds the high limit, that is, the electromagnetic control valve on the desalted water inlet pipe 5 is closed under the high-level liquid level, and the concentration at the current liquid level is calculated. After sufficient circulation of the circulation pipeline 6 and the circulation infusion pump 7, a part is discharged to the dilution transfer tank 3, and according to the concentration and the current liquid level at the current liquid level, it is calculated and further diluted to the target liquid level of the target concentration, and then discharged for use. Finally, the temporarily stored liquid in the dilution transfer tank 3 is returned, and according to the liquid level and the concentration, it is calculated and further diluted to the liquid level of the target concentration, and then discharged for use again.
