Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 1, 2, 3, a kind of water treatment system based on CEDI, comprises water inlet system, pollutant-removing system, cleaning system and pipeline; Described water inlet system is connected by pipeline with described pollutant-removing system; Described pollutant-removing system is connected with described cleaning system by pipeline; It is characterized in that: in described pollutant-removing system, be provided with two CEDI membrane stacks;
Preferably, described CEDI membrane stack is IP-LX membrane stack; Why adopt this IP-LX membrane stack, mainly because this membrane stack ripe water treatment technology---electrodialysis and ion-exchange combine by two kinds, the salt dissolved is removed under the condition of less energy-consumption, chemical regeneration is not needed in operational process, and its water outlet resistivity is taller compared with mixed bed water outlet, 10-18.2M Ω .CM can be reached, meet National Electrical level water I grade standard; If the size of running current and the size of chemical feeding quantity (sodium-chlor) only need be regulated when specific conductivity is higher; CEDI belongs to Environmentally-sound technology, and ion exchange resin does not need acid, alkali chemical regeneration, saves a large amount of acid, alkali and water for cleaning, greatly reduces labour intensity; The more important thing is that belong to the water treatment system of non-chemically formula, it is without the need to acid, the storage of alkali, process and the discharge without waste water without spent acid, waste lye discharge;
