Problems solved by technology

[0003] The reverse osmosis membrane technology in the prior art cannot readjust the water quality of the produced water, that is, the concentrated water cannot be filtered and utilized again, resulting in waste of water resources, and when the pure water in the produced water of the system is mixed with When the ratio of concentrated water exceeds 3:1, the risk of reverse osmosis membrane operation will increase, the purification rate will decrease, and the water quality of the produced water will also deteriorate accordingly

Abstract

The invention relates to a double-tank reversed-electrode electrodialysis water purification system and a table-board type water purifier thereof. The double-tank reversed-electrode electrodialysis water purification system is used for purifying water and provided with an original water tank, a concentrated water tank, an EDR unit capable of changing electrodes, a first electromagnetic valve, a second electromagnetic valve, a third electromagnetic valve and a fourth electromagnetic valve. Pipelines of original water and concentrated water into the EDR unit are changed through the first electromagnetic valve and the second electromagnetic valve, and outflow pipelines of original water and concentrated water generated by the EDR unit are changed through the third electromagnetic valve and the fourth electromagnetic valve, so that the electrode reversing operation of the EDR unit is completed; the backflow of the concentrated water generated by the EDR unit can be achieved through a concentrated water pipeline of the system, so that the concentrated water is filtered again, and the pure waste ratio of produced water is improved; by utilizing the double-tank structure of the water purification system, the stability of the EDR reversed-electrode electrodialysis water purification system can be improved; and the scaling risk of the system can be reduced through the regular electrodereversing operation of the EDR reversed-electrode electrodialysis water purification system.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a double-box inverted electrode electrodialysis water purification system and a table-top water purifier. Background technique [0002] Most of the existing reverse osmosis water purifiers use a reverse osmosis filter element (commonly called an RO membrane filter element) for water purification operation, and the reverse osmosis filter element has a reverse osmosis membrane. When the raw water enters the reverse osmosis water purifier, a certain pressure is applied to the raw water to make the water molecules and ionic mineral elements in the raw water pass through the reverse osmosis membrane, and the macromolecular inorganic salts in the raw water include heavy metal ions, organic matter, bacteria and Viruses cannot pass through the reverse osmosis membrane with small membrane pores to achieve water purification. [0003] The reverse osmosis membrane technology in the...
