Problems solved by technology
[0003] However, due to the working mechanism of the resin, in order to obtain better effluent water quality, the resin enters the regeneration and replacement process before being fully utilized in the ion exchange process. The recovery rate is low, and a large amount of acid and alkali solution and regeneration solution are consumed.
At the same time, because the regeneration and replacement control points are not well grasped, it often occurs that the resin regeneration is not complete or a large amount of acid-base waste liquid is discharged.

The present invention discloses a water purification system and a method for controlling the regeneration replacement treatment of ion floating beds of the water purification system. The water purification system comprises a plurality of cationic floating beds, a plurality of anionic floating beds, a plurality of water outlet tanks, a cationic bed regeneration / replacement water tank, an anionic bed regeneration / replacement water tank and a regeneration waste liquid collection water tank, each cationic floating bed is provided with a first-stage water inlet, a first-stage water outlet, a cationic bed regeneration replacement water inlet and a cationic bed regeneration replacement water outlet, each anionic floating bed is provided with a second-stage water inlet, a second-stage water outlet, an anionic bed regeneration replacement water inlet and an anionic bed regeneration replacement water outlet, the water purification system further comprises a first PH value meter, and the first PH value meter is arranged on the communication pipe for connecting the second-stage water outlet of one of the anionic floating beds and the water outlet tank, wherein whether the anionic floating bed is regenerated is determined according to the value of the first PH value meter during the operating process of the anionic floating bed.
Description
technical field [0001] The invention relates to the technical field of water purification, in particular to a water purification system and a method for controlling the regeneration and replacement treatment of an ion floating bed. Background technique [0002] At present, the commonly used advanced treatment processes for water purification include membrane method and ion exchange method. Membrane method is widely used for its advantages of stable operation, but the cost of reverse osmosis membrane is high, the one-time investment is large, and the chemical cleaning agent is expensive. Desalination treatment of water by anion and cation exchange method, the effluent quality is higher than that of membrane treatment, and the resin is cheaper, so ion exchange method is often used in the preparation of soft water. [0003] However, due to the working mechanism of the resin, in order to obtain better effluent quality, the resin has not been fully utilized in the ion exchange p...
