Abstract

The invention discloses an electro-adsorption desalting system, a regeneration system and a corresponding method and relates to the field of water treatment, in order to solve the problems of the present technology that the treating efficiency is lower and an electro-adsorption module is required to tolerate higher water pressure. The electro-adsorption desalting system comprises a raw water tank, a lifting pump, at least two-level serial electro-adsorption modules and a water generating tank which are serially connected in turn, wherein a middle water generating tank and a middle lifting pump in serial connection are also arranged between the at least two-level serial electro-adsorption modules. The regeneration system for the electro-adsorption modules comprises a raw water tank, a lifting pump, at least two-level serial electro-adsorption modules and a sewage tank in serial connection, wherein a middle water tank and a middle lifting pump in serial connection are arranged between the at least two-level serial electro-adsorption modules. In an electro-adsorption desalting technology, the demand on the pressure resistance of the electro-adsorption modules is not increased and the use ratio of the electro-adsorption modules is increased. In an electro-adsorption module regeneration technology, the demand on the pressure resistance of the electro-adsorption modules is not increased and the water yield is higher.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to an electric adsorption desalination system and method, and an electric adsorption module regeneration system and method. Background technique [0002] As a desalination technology with strong adaptability, simple maintenance, convenient operation and good treatment effect, Electrosorption Technology (Electrosorption Technology, EST) has gradually become the field of water treatment technology in recent years due to its good environmental protection and energy saving characteristics. a major research hotspot. Practical engineering applications show that the existing electro-adsorption desalination system is difficult to give full play to its advantages in the field of high brine treatment, which also limits the promotion and application of electro-adsorption technology to a certain extent. [0003] For general water quality, that is, when the salt content is not too high, the exist...
