Description
Technical field
The utility model relates to the tap water field of purification, refers in particular to a kind of tap water supply purification system that can obtain direct-drinking water.
Technical background
The quality of tap water quality is directly connected to the healthy of people, but, have bacterium, virus, pyrogen and " three cause thing (carcinogenic, teratogenesis, mutagenesis) " in the tap water supply system, form microorganism risk (generally being acute) and chemicals risk (generally being chronic) that drinking-water quality constitutes a threat to human body.
The microorganism risk is owing to cause a disease microbial in the tap water.That continues to use at present gives the water treatment idea, promptly adopts precipitation, filtration, disinfectant method, just can solve the pathogenic bacterium problem.Even more metropolitan length apart from water supply network, just can guarantee safety of drinking water as long as keep the certain chlorine residue of pipe network tip.But even find to keep certain chlorine residue, still detect tens kinds of bacteriums along with the progress of the reach of science and analytical technology nearly decades in the feedwater piping, except that minority iron bacteria and thiobacterium, mainly is to be the heterotrophic bacterium of nutraceutical matrix with the organism.Bacterium and intestinal bacteria detect examples that number increases than output water in the pipe network water report also the time.And the sterilization of tap water at present can not solve virus pollution, the pyrogen contamination of tap water supply system effectively.
The effective measure of avoiding the microorganism risk are not direct drinking public water supplies, but boiling tap water, but boil the chemicals risk that can't solve tap water.The HUMAN HEALTH utmost point to be had the micropollutant of threat enter drinking water resource by variety of way external except the organism of many synthetic such as Insecticides (tech) ﹠ Herbicides (tech), agricultural chemicals etc., finds that the disinfection byproduct (DBP) that chlorine disinfectant produces has bigger influence equally to HUMAN HEALTH the seventies.Increasing disinfection byproduct (DBP) such as haloform, halogen acetic acid, halo nitrile, halogenated aldehyde etc. are found in tap water.Wherein haloform and halogen acetic acid are that the intensive carinogenicity is arranged.
From above analysis as can be known, pollution of waterhead is affected the numerous urban water supply water quality of China.And along with growth in the living standard, the resident is to the drinking-water quality growing interest, thereby " supplying water in different qualities " notion has been proposed.So-called " supplying water in different qualities " is meant that establishing the pipe network supply in addition specializes in " pure water " of drinking (food) usefulness on a small quantity, and with Urban water supply as " general water ".The process system of popular supplying water in different qualities is an application foundation with the reverse osmosis membrane processing technology mainly at present.Water after the reverse-osmosis treated belongs to the pure water category, owing to do not have the indispensable micronutrient element of people in the water yet, as calcium, magnesium, iodine etc., the medical expert does not advocate people's long-term drinking pure water, distilled water, and all there is the limitation of self in present " supplying water in different qualities " mode of China at aspects such as facility investment, running cost, ton water cost, water quality, purposes.
Summary of the invention
The utility model is just in order to overcome above-mentioned deficiency, a kind of nano based high-quality water-supply purification system is provided, it is an application foundation with ultra-filtration membrane process and nano science, compare with traditional supplying water in different qualities purification techniques, have unique comprehensive advantage and effect at facility investment, the aspects such as security of making the water long-term drinking based on technology such as reverse osmosis, electrodialysis, nanofiltrations; Simultaneously,, make system can realize branch rate 50% or more easily, can be used as the ideal solution of tap water terminal purification because water producing cost, ton water cost are extremely low.
This programme is implemented like this: nano based high-quality water-supply purification system, comprise the ultra-filtration membrane filter element, it is characterized in that being provided with in the system functional filter element, the filtrate in the described functional filter element is that gac and sterilization property nano material are or/and the mixture of the plain inorganic particle of negative ion.The order of ultra-filtration membrane filter element and functional filter element can design arbitrarily in the native system, with the ultra-filtration membrane filter element formerly, functional filter element after design sequence be best.
Working pressure in the native system in the ultra-filtration membrane filter element is about 0.1-0.5MPa, the micropore size of ultra-filtration membrane is asked 0.005-1um's, the water of crossing through uf processing, suspended substance, colloid and particulate a large amount of in the water have not only been removed, make water become as clear as crystal, and removed materials such as organism, bacterium, virus, pyrogen, but kept trace mineral element to the human body beneficial;
Sterilization nano material in the functional filter element filtrate can slowly be released in the water body, and with process that micro-germ in the water contacts in play the effect of killing pathogenic bacteria.Simultaneously owing to dissolved in micro-nano material in the water body, make make kept in the water be similar to " chlorine residue ", we are referred to as the antibiont of " surplus receiving ", the existence of " surplus receiving " can suppress growth and the breeding of pipeline disease caused by infectious water bacterium effectively.
For the gac internal medium: in traditional structure, when equipment was in static condition, gac inside was to help the breeding of microorganism and growth most.Now, because the adding of sterilization property nano material, and this material can be in the internal medium of gac " shuttling back and forth " and " dissociating " arbitrarily, so, even have the microorganism of trace to exist in the water, also will under the effect of nano material, effectively be killed and suppress.Like this, can give full play to gac and remove the function that chlorine residue, three in the water causes harmful materials such as thing, part heavy metal ion, keep in the water body trace mineral element simultaneously the human body beneficial.It is limpid, transparent, aseptic to make water, can meet or exceed the drinking-water level of developed country, can drink raw safely.
The volume proportion of gac and sterilization property nano material designs at 4-9 in the functional filter element filtrate: between 1, the nanometer amount is very few, does not have the effect of effectively killing and suppressing germ; The nanometer amount is excessive, will reduce the loadings of gac in filter bed, thereby shortens the operation replacement cycle of filtrate in the secondary filter element.This sterilization nano material itself is without any side effects to human body, can be some nano inorganic anti-biotic materials, as nano zine oxide, nanometer silver and their mixture etc. thereof, with the nano zine oxide is example, its antibiotic mechanism is: when nano zine oxide when contacting with bacterium, zine ion slowly releases, because zine ion has oxidation-reduction quality, and can with organism (thio group, carboxyl, hydroxyl) reaction, can combine with bacterial cell membrane and membranin, destroy its structure, enter the enzyme that destroys electron transfer system behind the cell and, reach the sterilization purpose in the DNA reaction.After kill bacteria, zine ion can come out from endocellular liberation, repeats said process, and this also is the antibiotic persistent reason of zinc oxide.Compare with general inorganic antibacterial material, its advantage is:
1: specific surface area is big, and anti-microbial activity is stronger.
2: the surface atom quantity of nanoparticle is greatly more than traditional particle, and surface atom possesses very high-energy owing to lacking contiguous ligating atom, can strengthen the avidity of zinc oxide and bacterium, improves germ-resistant efficient.
3: for zinc oxide, nano-scale particle can improve photocatalytic effect greatly, produces transition of electron under illumination condition, and with transmission ofenergy, produces electronics and hole at ion surface, when water in the environment contact with oxygen, and generation negative oxygen ion and OH
-Ion, negative oxygen ion have very strong sterilizing power, and OH
-Ion can react with most of organism, impels its decomposition, can strengthen sterilizing power.
The plain inorganic particulate material of negative ion in the functional filter element filtrate is a kind of inorganic particulate material that some rare ores (jewel, jade etc.) are formed, it except having anti-microbial effect, some function that water is made in can also guarantee to drink water preferably mouthfeel and adjusting.The volume ratio of the plain inorganic particle of gac in the functional filter element filtrate and negative ion in filter bed is roughly 5-9: 1.Because the microelectrode characteristic of this negative ion element, when this particle contacted with water body, moment will discharge, and electrolysis takes place water molecules on every side immediately, and water molecules will resolve into the hydrogen ion (H that has positive electricity
+) and have the hydroxyl (OH of negative electricity
-).And hydrogen ion just combines and neutralizes with the electronics (e) that the negative ion element is emitted at once.Become hydrogen.Remaining hydroxy (hydroxyl, OH
-) become hydroxyl ion (H with on every side water molecules
3O
2 -), be electronegative ion.Because the existence of this negative ion element can produce some direct effects to HUMAN HEALTH, for example:
1. the pH value of regulating water is tending towards 7.2-8.2, is weakly alkaline.And human body fluid constant acid base equilibrium is the essential condition that keeps the cell eubolism.Blood PH is constant in this scope of 7.38-7.44, and average out to 7.4 is weakly alkaline.
2. antibacterial bacteriostatic, mould fungus inhibition: the negative ion element has permanent self power generation polarity, and in the electric field that this permanent electrode produced, bacterium and mould will be killed under little galvanic action or suppress its breeding.Antibacterial bacteriostatic rate＞97%.
3. increase oxygen in water: permanent electrode has reduced aerobic substance in the water, and the perviousness of water strengthens in addition, surface energy descends, and interfacial activity improves, make oxygen soluble in water in.
4. far infrared radiation rate:＞0.91 (2-18um wavelength region).Absorption of human body far infrared rays optimal wavelength is 9.6um, and the plain radiation infrared wavelength of negative ion is 2-18um, and the radiation power emission density is 0.04w/cm
2, than human body absorption radiosity 0.03w/cm
2Slightly high, so plain radiating far infrared rays of negative ion and human body are coordinated fine, can all be absorbed by human body.
Skin temperature is raise, and volume of blood flow increases 2-3 doubly, and the energy of far infrared rays is absorbed by the body water sub-resonance again, produces the angle vibration, can stimulate circulation, and strengthens metabolism.
5. molecule group diminishes: owing to the far infrared rays effect, cut off the chain of bound water molecule, become several by tens.The activity and the seepage force of this water are stronger, can promote the blood circulation of human body, strengthen the immunizing power that human body is resisted various diseases.
In order further to prevent the germ inlet, native system has been set up disinfection unit after above-mentioned filter element, be generally uv sterilisation, and it comprises independently uv steriliser and the water tank of being with ultraviolet lamp.The effect of this one-level is: even the trace that comes out in the secondary filter element leaked bacterium, also will be killed completely under the irradiation of ultraviolet lamp.Ultraviolet lamp is the premium properties of pathogenic microbe killing efficiently, simultaneously water body is not produced any side effect.
Be equipped with the variable frequency water supply control unit in the purification system described in the utility model, main effect is the resident who guarantees to feed to constant voltage water each floor.
Be provided with the microcirculation pipeline in the purification system described in the utility model, described microcirculation pipe connection building body and water tank.Its effect is: even pipeline water is in static condition (all users not the state during water), system will regularly make ducted water carry out reflux cycle, can effectively guarantee the breeding of water trace microorganism when leaving standstill like this.
Through above treatment system, make water remove clearly, transparent, aseptic, kept original trace mineral in the water body simultaneously to the human body beneficial, can reach real ideal direct-drinking water effect, native system is compared with " the 1-2% different water supply system " carried out at present, and it has following characteristics:
1. in the unitized construction of gac and ultra-filtration technique, compare, adjusted the handling procedure of the two, promptly ultrafiltration has been placed on before the gac with traditional processing mode.The partial organic substances of gac in can planar water, chlorination " three cause thing ", and the deleterious heavy metal element of part etc., in order to bring into play this usefulness of gac fully, prolong the replacement cycle of carbon leaching material to greatest extent, thereby must get rid of in advance contain in the water body, stop up suspended substance that activated carbon capillary sharply descends adsorptive value, colloid, bacterium, virus etc. easily, and ultra-filtration membrane has good removal effect to these materials.
2. in process for purifying water, introduce sterilization property nano material.Based on the sterilizing activity of some nano material with to the having no side effect of human body, can fully guarantee the breeding of microorganism in water body, in the gac filter bed.
3. the secondary filter element has been introduced " negative ion " crude granule material simultaneously.The mouthfeel of drinking-water can be suitably regulated in its application, and the fine setting effect favourable to some index of water body.
4. handle the same water yield, the investment of this equipment is below 30% of legacy equipment investment.
5. the ton water cost of the utility model processing is extremely low, can realize 50% above safety of drinking water under the situation that does not influence resident's moon water rate substantially easily.This point is that the present supplying water in different qualities equipment based on reverse osmosis is incomparable.
6. from making the character of water, the water of making of this purification system is more to meet healthy direct-drinking water.Because it has kept in the water body trace mineral element to the human body beneficial simultaneously.
