Description

Capacitive deionization device

Technical Field

The invention relates to a water treatment device, in particular to a water treatment device for electric desalting.

Background

At present, the mineralization degree of river water is directly improved by high-salinity wastewater in industrial wastewater and urban sewage, and more serious pollution is brought to soil, surface water and underground water, so that the ecological environment is endangered. The high salinity wastewater has high content of soluble substances and great treatment difficulty. The desalination process applied at home at present mainly comprises the following steps: chemical desalination (ion exchange), membrane separation techniques (electrodialysis and reverse osmosis), and thermal desalination (distillation).

The electro-adsorption desalination technology is a novel water treatment technology which is started in the last 90 th century, and the electro-adsorption desalination technology utilizes the charged characteristic of the surface of an electrified electrode to carry out electrostatic adsorption on ions in water so as to realize the aim of desalination. Because the technology adopts a brand-new water treatment concept, the technology has unique advantages in the aspects of treatment efficiency, adaptability, energy consumption, operation and maintenance, environmental friendliness and the like, and has good application and development prospects.

Most of salts in water treatment exist in an ionic state, and the basic idea of the electro-adsorption desalination technology is to force ions to move to electrodes with opposite charges by applying an external voltage to form an electrostatic field, so that the ions are enriched in double electric layers, the concentration of a solution body is greatly reduced, and the desalination of wastewater is realized.

The technology has good application and development prospect, and is expected to be widely applied to the aspect of recycling low-pollution-concentration high-salinity wastewater. Because an external power supply is needed, the sealing design of the external power line is complex and water leakage is easily caused, and improvement is needed.
