Description
Technical field
The utility model relates to a kind of EDI ultrapure water treatment facility.
Background technology
In the field such as biology, medicine, electronics, plating, in production, a lot of waste water can be produced.Its water quality is different because of production technique, containing metal ion with the existence of positively charged ion form and containing cyanogen, containing acid, containing alkali etc.Current water treatment method is RO reverse osmosis membrane treatment method, its principle uses high-pressure hydraulic pump, former water is added to+-20 kilograms of pressure, make former water penetrate under the effect of the pressure aperture only have the reverse osmosis membrane of 0.0001 micron, chemical example and bacterium, fungi, virosome not by, though non-water is discharged, volume is only allowed to be less than the water molecules of 0.0001 micron and to pass through.Water treatment method more advanced is at present by after water pretreatment, then adopts secondary RO system to process, but ion remaval is not thorough, and the water quality of process still can not reach ultrapure water standard, can not return and produce recycling, cause the waste at water source.
At water-treatment technology field, general employing second level reverse osmosis apparatus and EDI device in ultrapure water treatment facility, from pretreated water through second level reverse osmosis apparatus process, reverse osmosis produced water enters the process of EDI device, can obtain ultrapure water.The water of EDI water tank can because stopping property be poor, carbonic acid gas in air enters EDI water tank and causes deteriorating water quality, namely its resistivity declines rapidly, facts have proved, the ultrapure water of 18M more than Ω .cm expose in atmosphere after 1 minute water quality will drop to 10-15M Ω .cm, 2M Ω about .cm will be dropped to after 3 minutes.Therefore must reduce the chance that ultrapure water contacts with air, prevent ultrapure water container from being polluted by Carbon Dioxide in Air especially.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simplicity of design, water quality treatment capable of circulation and can produces the CDI ultrapure water treatment facility of high-quality ultrapure water.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of EDI ultrapure water treatment facility, comprise just pure water tank, filtration unit, EDI device and ultrapure water tank, described just pure water tank, filtration unit, EDI device are connected successively with ultrapure water tank, described filtration unit comprises activated carbon filtration film, microfiltration membrane and ultra-filtration membrane, described activated carbon filtration film, microfiltration membrane are connected successively with ultra-filtration membrane, described ultrapure water tank is communicated with U-shaped pipe, described U-shaped pipe is connected with and adds alkali mouth, described ultrapure water box top is provided with reflux, and described reflux is connected with first pure water tank.
As preferably, described just pure water tank and and filtration unit between be provided with topping-up pump.
As preferably, between described filtration unit and EDI device, be provided with measuring apparatus.
As preferably, between described filtration unit and EDI device, be provided with variable valve.
As preferably, described U-shaped pipe is connected with relief outlet, and described relief outlet is connected with control valve.
The beneficial effects of the utility model are: this EDI ultrapure water treatment facility simplicity of design, is separated dense water and fresh water by being provided with three layer filtration device, denseer water and fresh water are passed into EDI device carry out cation and anion exchange, can isolate ultrapure water to a greater extent; Be provided with the U-shaped pipe adding alkali in ultrapure water tank, can prevent entering of Carbon Dioxide in Air from affecting water quality; When ultrapure water tank soon completely time, reflux start ultrapure water is led to back at the beginning of pure water tank, realize the effect of circular treatment water quality.
