Abstract
The invention provides an electro-adsorption desalination technical method for continuous desalination work and an implementation device.The technical method and device can be used for seawater desalination or heavy metal treatment.Specifically, technical characteristics of electrodialysis multi-cavity and membrane capacitance deionized application ion-exchange membrane are combined.According to the technical method, by means of cooperative operation of the ion-exchange membrane and electrode material electro-adsorption, water in cavities is purified or condensed independently, and continuous desalination on the basis of a single desalination module is achieved.Produced desalted water and enriched saline water can be collected at the same time.Besides, on the basis of the work principle of the method, the device can further improve desalination handling capacity on the basis of electro-adsorption saturation of electrode materials.
Description
technical field [0001] The invention relates to an electro-adsorption desalination technology method capable of continuous desalination work and a realization device, belonging to the technical field of water treatment desalination. Background technique [0002] Capacitive deionization technology is a water treatment desalination technology based on the theory of electric double layer capacitance. Compared with other desalination technologies, such as reverse osmosis, membrane distillation, electrodialysis, ion exchange, multi-stage flash evaporation, etc., it has the comparative advantages of low energy consumption, no secondary pollution, and long material cycle life. The classic device model consists of a pair of parallel plate electrodes to form the main part, plus water flow guides, water flow drive devices and external power supplies. The electrode is composed of a current collector, an electrode material, a diaphragm, and an outer frame. After a low voltage is appli...
