Abstract

The utility model discloses a novel ultrapure water treating device, which comprises a pre-treating device, an active carbon filter, a 5 mum filter, a primary reverse osmosis device, a 1 mum filter, a secondary reverse osmosis device, a pure water pump, a TOC sterilizing box, a 0.1 mum filter, a UV sterilizer and a sterile water tank, all of which are sequentially connected. The whole device adopts automatic control taking a PLC as a control centre and is also provided with a set of manual control device; the mechanical equipment is effectively combined and utilized, and water quality processing is quick and effective; the novel ultrapure water treating device takes the PLC as the control centre, so the automatic control is realized, the stable production of the water quality is guaranteed and the influence of manual operation is reduced; manual control increases the stability of the device; a cleaning device and the treating device are closed devices and cleaning water is recycled, so the waste of a water resource is reduced and the water resource is saved; and because an EDI film stack is adopted, ion exchange is more thorough and ultrapure water with higher quality can be obtained.

Description

Novel ultrapure water treatment unit

Technical field

The utility model relates to a kind of water treatment device, relates in particular to a kind of ultrapure water treatment unit.

Background technology

Ultrapure water was for both almost completely to remove the conducting medium in the water, again with in the water not dissociative colloidalmaterial, gas and organism all be removed to the very water of low degree, its resistivity is greater than 18M Ω * cm, or near 18.3M Ω * cm ultimate value.Ultrapure water machine adopts pre-treatment, reverse osmosis technology, ultrapureization processing and back level to handle four big steps, cascade filtration, high-performance ion-exchange unit, ultra filtration filter, ultraviolet lamp, remove multiple treatment process such as TOC device, resistivity can reach 18.25M Ω * cm, and product is widely used in key industrys such as colleges and universities, scientific research, pharmaceutical factory, electric power, electronics, medical treatment, disease control, ring prison, technical supervising.The technology of traditional ultrapure water treatment unit is as follows: pretreatment unit-reverse osmosis unit-intermediate water tank-thick mixed bed-smart mixed bed-pure water case-pure water pump-ultraviolet sterilizer-polishing mixes bed-accurate filter-water object, this treatment unit usually adopts manually or semiautomatic controls, device is unstable, and do not have washing unit in the treating processes, water resource waste is serious.

The utility model content

The purpose of this utility model just is to provide a kind of novel ultrapure water treatment unit that addresses the above problem.

To achieve these goals, the technical solution adopted in the utility model is such: treatment unit comprises pretreatment unit, activated charcoal filter, 5 μ m strainers, the first-stage reverse osmosis device, 1 μ m strainer, the two-pass reverse osmosis device, pure water pump, the TOC sterilization box, 0.1 μ m strainer, UV sterilizer and abacterial water tank, they connect successively, it is the automatic control of control center that whole device adopts with PLC, the filtrate of pretreatment unit is fiber and quartz sand, pure water pump is the core original paper with EDI membrane stack (being the filling bed electrodialyzer membrane stack), between 5 μ m strainers and 1 μ m strainer, be provided with automatic flushing device, comprise and clean water tank and flushing water pump, described automatic flushing device and treatment unit form the loop line, also be provided with a cover manual control device, first-stage reverse osmosis device water outlet also is equipped with a pH value detector.

Compared with prior art, advantage of the present utility model is: effectively combination utilizes mechanical means, water quality treatment rapidly and efficiently; With PLC is control center, reality automatization control, guaranteed the stably manufactured of water quality and reduced to think the influence of operation; Also design simultaneously manually control of a cover, increased the stability of device; Increased automatic flushing device, washing unit is to be the device of a closure with treatment unit simultaneously, the water quality recycle of cleaning, reduce the waste of water resources, saved water resources, adopted the EDI membrane stack, ion-exchange is more thorough, can obtain higher-quality ultrapure water.

The utility model is described in further detail below in conjunction with accompanying drawing.

Description of drawings

Fig. 1 is a structured flowchart of the present utility model.

Embodiment

Referring to Fig. 1, after device started, pending former water entered pretreatment unit, and the fiber of the inside and quartz sand can be removed macrobead suspended substance in the water, thereby reduced the SDI value of water, removed look, flavor, chlorine residue and organism, removed iron, manganese in the water;

Water is through arriving activated charcoal filter after the more medium filter, can adsorb the chlorine residue that to remove in the prime filtration by activated charcoal filter and be subjected to its oxidative degradation to prevent a back level reverse osmosis membrane, also adsorb simultaneously from prime and leak the pollutants such as small organic molecule of coming, peculiar smell, colloid and pigment, heavy metal ion, COD (chemical oxygen demand (COD)) etc. in the water are had more significantly adsorb the removal effect.Can further reduce SDI (pollution index) value of feed water by reverse osmosis, guarantee SDI＜5, TOC (total organic carbon)＜2.0ppm;

Water by 5 μ m strainers, filters 5 μ m above particulate and bacterium through behind the activated charcoal filter, and entering one-level then is reverse osmosis unit, and reverse osmosis unit makes the solvent (being often referred to water) in the solution pass through the reverse osmosis membrane separation water outlet with enough pressure; At first-stage reverse osmosis device water outlet a pH value detector is installed, is detected the pH value size, if PH is higher than set(ting)value, the PH adder adds medicament in trend water, reduce pH value, close when being reduced to preset value PH adder, pH value is in the position of a running balance;

Water is through 1 μ m strainer then, filter 1 μ m above particulate and bacterium, arrive the two-pass reverse osmosis device again, arrive pure water pump through two-pass reverse osmosis device treated water, pure water pump is the core original paper with EDI membrane stack (being the filling bed electrodialyzer membrane stack), finishes the ion exchange treatment program;

Water enters the TOC sterilization box then, the TOC sterilization box not only can be used for sterilization and also can be used to fall TOC (total organic carbon) content and remove ozone, then by 0.1 μ m strainer, filter 0.1 μ m above particulate and bacterium, bacterium that the water quality of passing through is contained and particulate have reached the requirement of pure water, again by the UV sterilizer, the UV bacterium device that disappears utilizes the ultra-violet sterilization mode, sterilizing power with 1600 times of solar rays, and have the energy that is equivalent to 3600 degree heats, so can kill pathogen enterobacteria, the life bacterium of classes such as pyococcus, acarid, virus or the like.

Through sterilization later water quality, the electric conductivity detector of flowing through, the resistivity that detects water quality is greater than 18M Ω * cm, or near 18.3M Ω * cm ultimate value, the abacterial water tank of flowing through then.
