Description
Technical field
The present invention relates to a kind of desk-top water dispenser of circulation formula, belong to tap water terminal water conditioning technical field.
Background technology
Currently, water surrounding exacerbated, drinking water quality hygienic safety accident takes place frequently, and seriously jeopardizes the existence of people. The pollutent that water pollutions is mainly produced by mankind's activity causes, and it comprises industrial pollution source, agricultural pollution source and domestic pollution source three major part. Increasingly the water pollutions aggravated, forms significant threat to the living safety of the mankind, becomes the major obstacles of human health, economy and social sustainable development. According to the investigation of authoritative institution of the world, at least causing global 200d 00,000 people dead because drinking unhygienic water every year, therefore, water pollutions is referred to as " world's number one killer ".
Domestic and international most of waterworks still adopts the outmoded processing method of precipitation, filtration, chlorination so far, and river or underground water are simply processed into drinkable water. But, to spread unchecked in the face of industrial sewage, rural sewage and sanitary sewage wildness and pour in life water source, waterworks can't bear the heavy load helpless. Adding the additional pollution that tap water brings through water transfer pipe network and high-rise water tank arrival tap water terminal from water factory, municipal tap water dare not say it is health. Especially, although tap water chlorination can effectively kill except germ, but also producing more halogenated hydrocarbon compound, the content of these chlorinated organics is multiplied, and is the significant source causing the mankind to suffer from various disease simultaneously. Even boiling tap water, what above-mentioned residue still drove does not go, and the carcinogens such as nitrite and trichloromethane also can be made to increase. That is, even if the safety coefficient of drinking water is also not high.
Existing purification of water quality product or product of paddling, be mainly medium absorption or adopt the filtering membrane in various aperture that the nuisance in water is tackled the physics mode treatment process of filtering. Owing to gac class sorbing material is easy to saturated inefficacy, and various filtering membrane is easy to be contaminated by bacterial or organism obstruction or damaged, and therefore practical situation to accomplish the abundant purification to water pollutant as desired by Design Theory. In the face of day by day serious source water pollutions, existing physics mode treatment process can not ensure water quality reaching standard far away. But physics mode water technology also has an advantage, toxic byproduct can not be generated exactly. Therefore the water quality that traditional RO membrane reverse osmosis filter method is produced is the safest, but the cost exchanged for for protecting safety is then be wasted up to the even more converse dense water of 40%-70% to enter sewer line, cause huge water resources and waste of energy, and the cost changed after the blocking of RO film is very high.For reducing and even reach no effuent discharge, saving water resource, develop various patented technology so far. Such as, converse dense water is stored it use, or the pollutent in dense water is first filtered Posterior circle reuse through molecular sieve etc., or adjustment waste water ratio, or reduce cleaning blowing time by electrical control, or directly return dilution in tap water supervisor road through reverse checkvalve, or with " the two water of two film " pattern, water quality based water utilization, etc. The common deficiency of these technology, one is do not consider from overall system design, and just the single measure in local, often makes system overall work unbalance; It two is all do not consider that the water inlet operating mode from improving membrane element is started with, and alleviates the working load of membrane element, it can be said that " curing the symptoms, not the disease ", comes out so yet there are no the product of real utility goods so far.
Comparatively speaking, although Water Treatment technique has the plurality of advantages such as cheapness is simply efficient, it it is a kind of excellent advanced oxidation processes, but there is a series of problem in electrochemical treatment itself, occasion should not be processed at civilian terminal Drinking Water to be used alone, there is not yet so far in daily life water treatment occasion widespread use. Tracing it to its cause, one is that Water Treatment technique needs the enough reaction times, and in daily life water occasion, water purifier is from start to the water outlet only several seconds, and pollutent residence time in water purifier is too short, has had little time related chemistry reaction treatment at all; It two is that Water Treatment technique is likely with certain toxic side effect. Such as, although chemical oxidation reaction technique can potent inactivation of bacterial, depth degradation organism, remove the various objectionable impuritiess in water, but all kinds of Strong oxdiative factors that chemical oxidization method generates are non-selectivity, uncontrollable substantially, if dealing with the novel substance producing in the water of source most probably not have improperly, jeopardize safe drinking water on the contrary; Just because of this, process occasion at common people's daily life drink water purifying, for the application of Water Treatment technique it may be said that be double cautious.
But, in today that the unprecedented severe contamination of water surrounding, conventional physical water purifier are unable to do what one wishes, again the possibility that Water Treatment is applied is paid close attention in close examination in Drinking Water purifying treatment, it is ensured that people's life drinking water quality safety, is of great practical significance.
Summary of the invention
The present invention wants the technical solution problem to be: provide a kind of desk-top water dispenser that can not produce toxic byproduct and reliable operation long service life reducing bacterium in water hardness, degraded Organic substance in water, Inactivation in Water while.

The preferred micro-filtrate membrane filtration unit of membrane filter unit described in the present invention, ultrafiltration membrance filter unit or nanofiltration membrane unit.
The working mechanism of the present invention and the useful effect brought are presented below.
Described water capacity device of crossing is taking first, second water-permeable barrier film as boundary: described first electrode pair divides and is located at the first water-permeable barrier film both sides, and the negative electrode of described first electrode pair is crossing in water capacity device, and its positive electrode is being crossed outside water capacity device; Described 2nd electrode pair divides and is located at the 2nd water-permeable barrier film both sides, and the positive electrode of described 2nd electrode pair is crossing in water capacity device, and its negative electrode is being crossed outside water capacity device. Certainly, as cross water internal tank be provided with cavity, first or the 2nd water-permeable barrier film be arranged on cavity housing, then the negative electrode of the 2nd electrode pair or the positive electrode of the first electrode pair that are arranged in cavity are considered as being arranged on outside water capacity device.
First for the first electrode pair, the positive electrode of the first electrode pair only contacts (positive electrode does not directly contact with the water crossing water capacity device) with the infiltration water penetrating through the first water-permeable barrier film in water capacity device excessively, anode direct oxidation is reacted outside water capacity device has been in transfer and carries out, reaction product of anode is drained outside container, unlikely returns container internal contamination water quality again. Meanwhile, negative pollutent such as chlorine residue, the various harmful anions etc. in water, by anode voltage effect, it is also possible to through the first water-permeable barrier film water in container, and migration is discharged with infiltration water outside being water capacity device.
In the present invention, the structure of the first water-permeable barrier film shows as the water passage area excessively of countless permeable micropore on microcosmic, owing to the first water-permeable barrier film is that non-conductive material is made, thus volts lost is produced crossing in water passage of permeable micropore, namely when the electrolysis voltage of electrolysis power applies after outer electrode (positive electrode) and interior electrode (negative electrode), form following voltage-drop relation: the outer positive electrode of the first water-permeable barrier film (+) volts lost U3 that between pressure drop U2 → the first water-permeable barrier film that between → positive electrode and the first water-permeable barrier film, volts lost U1 → self impedance of water-permeable barrier film of water film produces and the negative electrode crossed in water capacity device, water impedance produces.
And the positive electrode of the first electrode pair only infiltration water with the first water-permeable barrier film contact, the positive electrode of the first electrode pair presses close to the first water-permeable barrier film, liberation of hydrogen during such water electrolysis, the gas that oxygen evolution reaction generates is easy to enter crossing in water passage and generating bubble in the water crossed in water passage of permeable micropore, in the narrow and small environment crossed in water passage of the permeable micropore of the first water-permeable barrier film, bubble is easy to fragmentation thus produces localized hyperthermia's high pressure, and then inspire the electric discharge of efficient water body plasma with minimum voltage, in the first water-permeable barrier film and the first water-permeable barrier film neighboring area water generates the plasma body of hydroxyl radical free radical class transient state oxidation factor (plasma body is with solid-state, liquid, gaseous state is in material the 4th state of same level, low-temperature plasma is rich in electronics, ion, free radical and excited state molecule, electronics and ion have very high reactive behavior, the chemical reaction being difficult under can making usual conditions carry out or speed is difficult to becomes very rapid, plasma group is generated by water body electric discharge, can greatly improve the degradation efficiency of pollutent in water body), the oxidisability of this hydroxyl radical free radical transient state oxidation factor extremely strong (exceeding ozone), lifetime in water is extremely short again simultaneously, therefore rapidly the pollutents such as Organic substance in water (such as bacterium) can be formed extremely strong Degradation after generation and directly be reduced to water after self rapid oxidation, do not stay any toxic side effect.
2nd electrode pair and the first electrode pair are similar, but the direction of voltage-drop is contrary. Therefore same, in the present invention, the negative electrode of the 2nd electrode pair contacts with the infiltration water of the 2nd water-permeable barrier film and can be used for ensureing that the electrolytic reaction of the 2nd electrode pair normally carries out, it is possible to produce great amount of hydroxy group radical type transient state oxidation factor.
Simultaneously, under the effect of the 2nd electrode pair, cross the lasting precipitations such as metallic cation such as the calcium ions and magnesium ions in the endogenous water of water capacity device, iron manganese, discharge through the 2nd water-permeable barrier film, making water hardness in water capacity device continue decline, in the water of source, harmful heavy metal etc. are progressively removed; And based on crossing the direct oxidation effect of the anode of the 2nd electrode pair in water capacity device, the microorganism in the water of source is inactivated, and organism is degraded.
In addition, the negative electrode of the first electrode pair and the positive electrode equivalence of the 2nd electrode pair form the 3rd group of electrode pair (without barrier film between yin, yang electrode), the microorganism in the water of source are inactivated under its electric field action, it is possible to the better cleaning action playing electrochemistry.
The present invention is in use, first source water carry out electrochemical treatment through described electrolysis cells, the oxymuriate of calcium ions and magnesium ions in the water of source, iron manganese and strong oxidizing property, hypochlorite are discharged water capacity device from crossing, and by hydroxyl radical free radical class transient state oxidation factor, source water is carried out sterilization and organic matter degradation, (toxic byproduct is only a small amount of H then to tackle residual harmful substance in filtering water through the further physics of described membrane filter unit2O2And O3, H2O2And O3Half life of decomposition be generally no more than half an hour, not only the filter assemblies of rear end or absorbent module can not be produced detrimentally affect, and filter assembly or absorbent module can be carried out sterilization and disinfection), thus obtain purifying waste water of the degree of depth. The present invention adopts the combination of " preposition electrochemical treatment and membrane filtration postpositive disposal ", thus overcome the various defects (the easy broken invalid of the filtering membrane mentioned in such as prior art, heavy metals exceeding standard etc.) of the combination of " physical adsorption-membrane filtration pre-process and electrolysis water unit postpositive disposal " in background technology, obtain required pure water.
The present invention is provided with topping-up pump between described first water outlet and the 2nd water-in, it is provided with T-valve between described topping-up pump and the 2nd water-in, the entrance of described T-valve is connected with supercharging pump outlet, first outlet of described T-valve is connected with the 2nd water-in, 2nd outlet of described T-valve is connected with the 3rd water-in, and the 3rd water outlet is connected with the first water-in. Like this, described T-valve just has two states, it is the first state and the two-state that supercharging pump outlet is connected with the 2nd water-in that supercharging pump outlet is connected with the 3rd water-in respectively, when T-valve is in two-state, so that it may to obtain healthy tap water; When T-valve is in the first state, the current in water tank can be made to move up, constantly pass through from crossing water capacity device, thus realize cyclic electrolysis, various zwitterions in water are in electrolytic reaction process, from crossing through first, second water-permeable barrier film in water capacity device, migration is drained outside being water capacity device, and the water quality in water tank is constantly purified.
In the present invention, membrane filter unit is pure physical treatment mode, ensure that the tight security of effluent quality especially Biological indicators, and the pollutent in the water of source of the present invention before entering membrane filter unit, base conditioning is clean, therefore the working load of membrane filter unit alleviates greatly, correspondingly, the work-ing life of membrane filter unit extends greatly, reaches the effect (water quality of purifying waste water of long service life and generation is good) taken stopgap measures and effect a permanent cure.
Owing to first, second water-permeable barrier film obtains the clamping protection of paired electrode in the present invention, test proves, first, second water-permeable barrier film in use can not be scrapped because of premature failure such as damaged or obstructions, remains reliable and stable working order; Even if occasionally having fouling to be also scum loosely at first, second water-permeable barrier film and electrode surface, electrolytic process is suitably switched the electrolysis voltage polarity of the paired electrode being applied to first, second water-permeable barrier film both sides, so that it may to remove anions and canons precipitate easily in the deposition fouling of electrode and water-permeable membrane surface.
The present invention is when implementing; according to actual needs the polarity of two electrode pairs regularly can also be swung to; now voltage range can not also be identical; thus make first, second water-permeable barrier film replace degradation of organic substances, discharge harmful heavy metal ions; or discharge residual chlorine residue, various harmful anions etc., so not only can improve the quality purified waste water further, give full play to the cleaning action of electrochemistry; and first, second water-permeable barrier film can be protected, extend its work-ing life.
In order to improve the medium ionic discharge characteristic of film further, it is possible to make described first water-permeable barrier film and the 2nd water-permeable barrier film all adopt hydrophilic barrier film. Hydrophilic film surface energy and water form hydrogen bond ordered structure, it is possible to improve film hole water-filling wet face state, be conducive to the medium ionic discharge process of film to continue to carry out.
Preferably, the aperture size of the permeable micropore of described first water-permeable barrier film is substantially identical, and the aperture size of the permeable micropore of described 2nd water-permeable barrier film is also substantially identical.
In the present invention, if the permeable aperture of first, second water-permeable barrier film excessive (namely microporous space is excessive) equivalence causes the initial exciting voltage of discharge in water to increase in a disguised form increasing electrode diameter (electrode curvature radius), and generation bubble volume is made to become the specific surface area reducing greatly gas-liquid two-phase contact reacts. And the permeable aperture of first, second water-permeable barrier film if excessively little (namely microporous space is excessively little), can make electrolysis produce gas cannot occur or gas producing efficiency extremely low, little the point discharge of numerous small curvature radius electrode in each micropore in barrier film can be caused to a certain extent normally to carry out. Therefore, through the repetition test of contriver, it is determined that the permeable pore diameter range of first, second water-permeable barrier film is less than or equal to 2 millimeters and be more than or equal to 1 nanometer.
The shape uniformity of membrane micropore and the homogeneity of pore size are very big on the impact of film medium ionic discharge. In order to better more generation hydroxyl radical free radical plasma group, it is preferable that, in use, each permeable micropore of described first water-permeable barrier film and the 2nd water-permeable barrier film all forms plasma electric discharge. Like this when using electric discharge, direction of an electric field between anodic-cathodic can through the plasma group of each permeable micropore, all mistake in water passage that plasma electric discharge is directed to water-permeable barrier film carries out, thus the electric discharge of water body plasma can be inspired with minimum voltage, water generates the transient state oxidation factor having sterilizing ability in a large number, can greatly improve the degradation efficiency of pollutent in water body, better carry out sterilization and disinfection etc.
Better wetting ability can be made it have by barrier film is carried out modification, and the aperture size of micropore is even, concrete modified technique can adopt known physics or chemical process technology, such as film hole regularization shaping, optically catalytic TiO 2, extremely narrow high-voltage pulse to film pre-treatment, etc.Its meaning is not only the raising of efficiency, also effectively prevent the deterioration easily causing biological index because current density is excessive.
