Water treatment device and water treatment system

Abstract

The invention discloses a water treatment device and a water treatment system. The water treatment device comprises a plurality of sets of water treatment rooms which are sequentially arranged from left to right, an electrode plate is arranged on each of the inner sides of the left side wall and the right side wall of each water treatment room; two filter membranes are arranged between the two electrode plates in each water treatment room; a partition is arranged between the two filter membranes in each water treatment room, as well as between the adjacent filter membranes and electrode plates; the adjacent electrode plates and filter membranes in each water treatment room and the partitions between the electrode plates and the filter membranes form a concentrated water room; the two filter membranes in each water treatment room and the partition between the two filter membranes form a fresh water room. The water treatment system comprises a primary water treatment device, a water desalination system and a water concentration system. The water treatment device and the water treatment system have the advantages of being resistant to high temperature, acid and alkali and organic solvents, are low in price and greatly reduce the water treatment cost.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a water treatment device and a water treatment system. Background technique [0002] Current water treatment devices mainly use methods such as reverse osmosis, electrodialysis, and electrosorption to separate water and salt. Among them, the treatment methods of reverse osmosis and electrodialysis do not have the effect of high temperature resistance and acid and alkali corrosion resistance, and there is a limit to the concentration of free chlorine. However, only when the salt concentration is very low can the electrosorption meet the water requirements of the electrosorption equipment, and the highest conductivity cannot exceed 5000us / cm. Among the three treatment methods of reverse osmosis, electrodialysis and electroadsorption, only electrodialysis equipment can desalinate and concentrate concentrated water. With the strengthening of environmental protection awarene...

AI Technical Summary

Problems solved by technology

However, the application in the treatment of sewage with high temperature, high acid-base salt concentration and high organic solvent concentration in petrochemical enterprises is almost zero.

The reason is that the production cost of high-end ion-exchange membranes resistant to high temperature, acid and alkali, and organic matter is very high, which makes high-end ion-exchange membranes very expensive and has not been widely used.
