Abstract

The invention discloses a high-salinity water body desalting system based on an electro-adsorption technology. The system comprises a pretreatment tank, an adsorption tank communicated with the pretreatment tank through a pipeline, a first pump arranged on a communication pipeline of the pretreatment tank and the adsorption tank, an electric adsorption assembly arranged in the adsorption tank, a water outlet tank communicated with the adsorption tank through a pipeline, a monitoring assembly for monitoring TDS and conductivity in the water outlet tank, a short-circuit circuit electrically connected with the electric adsorption assembly and enabling the electric adsorption assembly to be short-circuited, a control switch controling the short-circuit circuit to be connected or disconnected, a control unit controling the control switch to act according to the monitoring result of the monitoring assembly, and a cleaning system communicated with the adsorption tank for cleaning the adsorption tank. The control unit is electrically connected with the first pump. The system has the advantages of low energy consumption, high desalting rate, no need of using a high-valence membrane, simplicity in maintenance, no secondary pollution and the like.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a high-salt water desalination system based on electric adsorption technology. Background technique [0002] The distribution of global freshwater resources is uneven, and serious water pollution in recent years has led to water shortages and water security issues in various countries in various degrees. Among them, the discharge of high-salt sewage poses a huge threat to the health of humans and animals. The current main desalination technologies include: ion exchange technology, electrodialysis, RO reverse osmosis and electro-adsorption. Ion exchange technology can efficiently treat 1000-20000mg / L TDS high-salt wastewater, but ion exchange resins have strong specificity, and it is difficult to efficiently treat sewage with complex components, and the cost is relatively high. The price of resin reaches tens of thousands of yuan per ton. Electrodialysis can e...
