Description
Technical field
The present invention relates to water treatment field, specifically a kind of electrically driven (operated) film desalination unit and use the water treatment method of this unit.
Background technology
Electrodialysis, is called for short ED method, is utilize anions and canons exchange membrane to be alternately arranged between positive and negative electrode, and is separated with special dividing plate, the desalination of composition desalination and concentrated two systems.After leading to people's salt solution to compartment, under DC electric field effect, positively charged ion moves to negative pole, and can only pass through cationic exchange membrane, and negatively charged ion moves to positive pole, and can only pass through anion-exchange membrane, and the salt solution in light room is desalinated, the salt solution in dense room is concentrated.But in operational process, because negative electrode and dense room are in alkalescence, the film of room, negative electrode pole and both sides, dense room easily occur scale formation, thus affects effluent quality, and shorten service life of equipment.Frequently pole-reversing electroosmosis (being called for short EDR) has been born subsequently, and its appearance is an important breakthrough of electrodialytic technique.It is by switching the switching in polarity of electrode and cooperation water route, the water drainage-supply system achieving light room and dense room is changed, equipment being called oneself and creates self-stip ability---dense room and negative electrode are becoming light room and anode extremely afterwards, acid-basicity becomes acidity from alkalescence, and the dirt tied is come off by pickling and to go out with current.So namely, ensure that the permanent stability of ion-exchange membrane, in turn ensure that the stable of effluent quality.
Current electrodialyzer main body is by locking frame, water dispensing board (battery lead plate of holding concurrently), porous plate and membrane stack composition.Locking frame is welded by square steel pipe or channel-section steel one class.Water dispensing board adopts pvc plate to make, play a part to guide dense, fresh water to pass in and out membrane stack, and battery lead plate is then used to fixed electorde, and generally these two kinds of plates can merge.Porous plate adopts pvc plate to make equally, plays protection membrane stack, enclosed electrode room.Membrane stack is generally according to pole film (anode membrane)---dividing plate---cavity block---dividing plate---anode membrane---dividing plate ... cavity block---dividing plate---pole film (anode membrane) arranges.
At present, prior art Problems existing is:
1. the control of falling pole of frequently pole-reversing electroosmosis is accurate not at present.
2. lack effective pressure protect measure, often occur the intermembranous damaged drainage because hypertonia causes.
3. existing electrodialyzer locking frame directly clamps the water dispensing board of pvc material, and intensity is low, easily occurs the problem of sheet material fatigue.
4. because water dispensing board and porous plate all adopt pvc plate to make, and pvc plate belongs to soft material, and the thickness of plate evenly differs, and plate face very easily occurs cut adding man-hour, if the cut of appearance is dealt with improperly, can breakseal face, and cause the seepage of pole water.
5. at present vertical electric dialysis, the Inlet and outlet water of electrode all adopts laterally leakes water, and vertical with its water (flow) direction in a device, be unfavorable on the one hand getting rid of the gas in electrode vessel, another aspect is unfavorable for that the time of falling pole goes out the dirty body come off in electrode vessel.
6. existing electrodialyzer membrane stack both sides film body is directly exposed, lacks and effectively protects.
7. lacking traffic protection measure, often there is the burning film phenomenon caused because blocking causes underfed in membrane stack.
8. existing frequently pole-reversing electroosmosis generally adopts the form of one-level one section, though control simple, floor space is large, and pipeline is complicated.
