Description
Technical field
The present invention relates to a kind of micro- discharge water purification machines, belong to drinking water terminal water treatment technical field.
Background technology
Currently, water environment is exacerbated, the safe and healthy Frequent Accidents of drinking water quality, seriously jeopardizes the existence of people.Water
The pollutant that pollution is mainly generated by mankind's activity causes, it includes industrial pollution source, agricultural pollution source and domestic pollution source
Three parts.Increasingly the water pollution aggravated, to the living safety of the mankind form significant threat, become human health, economy and
The major obstacles of social sustainable development.It is investigated according to authoritative institution of the world, every year the whole world caused by drinking unhygienic water at least
20000000 people are dead, and therefore, water pollution is referred to as " world's number one killer ".
Domestic and international most of waterworks are so far still using precipitating, filtering, the outmoded process of chlorination, by rivers
Water or underground water are simply processed into drinkable water.However, it spreads unchecked and pours in face of trade effluent, rural sewage and sanitary sewage wildness
Life water source, waterworks can't bear the heavy load helpless.Along with tap water from water factory through water transfer pipe network and high-rise water storage
Case reaches and pollution is added caused by drinking water terminal, and it is health that municipal tap water dare not have been said.Especially, tap water adds
Although chlorine can be killed effectively except germ, can also generate more halogenated hydrocarbon compound simultaneously, the contents of these chlorinated organics into
Increase again, be the significant source that the mankind is caused to suffer from various diseases.Even boiling tap water, above-mentioned residue still drive no
It goes, the carcinogenic substances such as nitrite and chloroform can also increased.Also that is, even if the safety coefficient of drinking water is also not high
's.
Existing purification of water quality product or drinking water related product, predominantly medium adsorb or will be in water using the filter membrane in various apertures
Nuisance intercepted the physics mode treatment process filtered out.Since activated carbon class sorbing material is easy to saturation failure, and
Various filter membranes are easy to be contaminated by bacterial again or organic matter obstruction or damaged, thus actual conditions be can not be such as Theoretical Design
It is desired to accomplish like that the sufficiently cleaned up of water pollutant.At the source water pollution of getting worse, existing physics mode
Science and engineering skill far can not ensure water quality reaching standard.But physics mode water treatment technology also has an advantage in that, will not exactly generate
Toxic byproduct.Therefore the water quality of traditional RO membrane reverse osmosis filter method production is the safest, but is exchanged for the generation that ensures safety
Valency is then up to the even more converse concentrated waters of 40%-70% and is wasted be discharged into sewer pipe, cause huge water resource and
Waste of energy, and the cost replaced after the blocking of RO films is very high.To reduce or even reach no effuent discharge, water resource is saved,
Various patented technologies are had been developed that so far.It is used or by the pollutant in concentrated water first through molecular sieve for example, converse concentrated water is stored it
It is reduced Deng filtering Posterior circle reuse or adjustment waste water ratio or by electrical control and cleans blowing time or direct through non-return valve
It returns and is diluted in tap water main line or with " the double water of double films " pattern, water quality based water utilization, etc..The common deficiency of these technologies, one
It is not consider from overall system design, only the single measure in part, often makes system overall work unbalance；The second is do not consider
From starting with into water condition for membrane component is improved, mitigate the live load of membrane component, it may be said that it is " palliative ", so so far
The product that yet there are no real utility goods comes out.
In comparison, it is a kind of excellent height although Water Treatment technique has cheap many advantages, such as being simple and efficient
Grade oxidation technology, but there are a series of problems in itself for electrochemical treatments, should not handle occasion list in civilian terminal Drinking Water
It solely uses, so far there is not yet in daily life water treatment field and closes extensive use.To find out its cause, one is Water Treatment technique
The enough reaction time is needed, and in daily life water occasion, only several seconds, pollutant exist water purifier from be switched on to being discharged
The residence time is too short in water purifier, has little time to complete related chemistry reaction treatment at all；The second is have can for Water Treatment technique
It can be with certain toxic side effect.For example, although chemical oxidation reaction technique can potent inactivation of bacterial, depth degradation organic matter,
Go water removal in various harmful substances, but all kinds of Strong oxdiative factors that chemical oxidization method is generated be substantially non-selectivity, can not
Control, if dealing with the novel substance not having in most probably generating source water improperly, jeopardize safe drinking water instead；Just because of this, in the people
Many daily life drink water purifyings handle occasion, the application of Water Treatment technique can be described as double cautious.
However, in the unprecedented serious pollution of water environment, conventional physical water purifier today unable to do what one wishes, examine closely again
The possibility that concern Water Treatment is applied in Drinking Water purified treatment, innovative development one kind can efficiently remove dirty in water
Object non-toxic by-products, highly safe chemical oxidation method for purifying water and device again are contaminated, by physical absorption-filtration treatment technique
It is combined with electrochemical treatments technique, displays one's respective advantages, learn from other's strong points to offset one's weaknesses, it is ensured that people's life drinking water quality safety has very
Important realistic meaning.
Although presently commercially available electrolytic ion water dispenser water treatment system substantially can be considered physical absorption-filtration treatment work
Skill is combined with electrochemical treatments technique, but its system structure is the preposition processing of physical absorption-membrane filtration and electrolysis water unit
The combination of postposition.Regrettably, for purification of water quality, this " putting the cart before the horse " frame mode does not overcome simple physical to inhale
The deficiency of attached-membrane filtration processing capacity, such as is commonly used for the activated carbon of pre-treatment, and porosity high-specific surface area nonpolarity is inhaled
Attached characteristic has preferable deodorization, decoloration, removal chlorine residue, filtering suspended matter and filters out the organic matter that molecular weight is more than 3000
Effect.However, the protection to filter membrane is inadequate, the absorption of some organic matters cannot decompose on filter membrane causes film to fail, activity
Charcoal saturation failure or even becomes the hotbed of bacteria breed so as to further block filter membrane, etc. easily by germ contamination.Before
It handles unqualified so that reverse osmosis membrane or ultrafiltration membrane are stained significantly and broken invalid.Postposition electrochemical treatments technique also can band
Carry out many new problems, such as cathodic reduction can generate nitrite, heavy metal ion and cannot filter out and lead to heavy metals exceeding standard
Deng it is not up to standard to eventually lead to water purifier.
Invention content
The invention solves technical problems to be：There is provided that a kind of wastewater discharge is few, water purification index is good, reliable operation and use
The water purification machine of long lifespan.
In order to solve the above-mentioned technical problem, technical solution proposed by the present invention is：A kind of micro- discharge water purification machine, including electrolysis
Unit, reverse osmosis membrane processing unit and finished product water tank；The electrolysis cells include at least a pair of of anodic-cathodic, are negative and positive electricity
Pole power supply electrolysis power and source water tank, between pairs of negative electrode and positive electrode be equipped with water penetration diaphragm, the water penetration every
Film is water penetration diaphragm made of non-conductive material；The source water tank is equipped with the first water inlet and the first water outlet, described
Water penetration diaphragm separates positive electrode and the source water tank, and the negative electrode is located in the water tank of source；Be equipped in the source water tank into
The porosity sorbing material of block, first water outlet are arranged on porosity sorbing material；The reverse osmosis membrane processing unit
It is exported equipped with the second water inlet, pure water outlet and concentrated water, first water outlet is connected with the second water inlet, the reverse osmosis membrane
The pure water outlet of processing unit is connected with finished product water tank, and the concentrated water outlet of the reverse osmosis membrane processing unit is connected with source water tank；
When in use, the negative electrode is in direct contact with the water in the source water tank, and the positive electrode only passes through saturating with the source water tank
The infiltration water contact of aqueous diaphragm exudation.
It should be noted that the object that the present invention is handled, which is city, supplies tap water, as described in the background art, present water is dirty
Getting worse is contaminated, city has become a kind of micro-polluted water for tap water（Special contamination water in other words）, pollution sources include ring
It pollutes in border（Such as pesticide residue）, the pollution that generates of chlorination and pipeline secondary pollution etc..
The working mechanism and advantageous effect of the invention described above are specifically presented below：
Using water penetration diaphragm as boundary, pairs of negative electrode and positive electrode set up separately in water penetration heretofore described source water tank
Diaphragm both sides, the negative electrode is in the water tank of source, and the positive electrode is outside the water tank of source.Certainly, as source water tank is internally provided with cavity,
Water penetration diaphragm is arranged on cavity housing, then the positive electrode being arranged in cavity, which is considered as, to be arranged on outside the water tank of source.
Heretofore described positive electrode is only contacted with penetrating through the infiltration water of water penetration diaphragm in the water tank of source（Positive electrode is not
It is in direct contact with the water of source water tank）, anode direct oxidation reaction is transferred to outside the water tank of source and is carried out, reaction product of anode is in container
Drain outside, pollution water quality in container will not be returned again to.Meanwhile such as chlorine residue, various harmful anions of the negative pollutant in water
Deng, acted on by positive electricity pole tension, can also out of container in water through water penetration diaphragm, it is outer with infiltration water row to move to source water tank
Go out.
Therefore, the various zwitterions in the water of source during cell reaction, pass through permeable out of source water tank when in use
Property diaphragm, move to and exhaust outside the water tank of source.And the zwitterion in water is the TDS for forming water（That is dissolvability solid amount）Master
Factor is wanted, under electrolysis, the zwitterion in water is mainly arranged through the interelectrode water penetration diaphragm of yin, yang with efflux wastewater
Go out, in this way, the TDS of source Water in Water Tanks is just reduced, do not have so as to maintain the TDS of water in system compared to city for water supply water
There is notable raising.By taking DaLian, China area as an example, city is 100 ~ 150mg/L for the TDS of tap water, and concentrates efflux wastewater
TDS is up to 14000mg/L.
The structure of water penetration diaphragm shows as the water passage region of countless permeable micropores on microcosmic in the present invention, due to
Water penetration diaphragm is made of non-conductive material, thus voltage drop is generated in the water passage of permeable micropore, i.e., when electrolysis electricity
The decomposition voltage in source is applied to external electrode（Positive electrode）With interior electrode（Negative electrode）Afterwards, following voltage landing relationship is formed：Thoroughly
The outer positive electrode of aqueous diaphragm（+）The voltage drop U1 of moisture film → water penetration diaphragm direct impedance between → positive electrode and water penetration diaphragm
The voltage drop U3 of the anti-generation of water resistance between negative electrode in pressure drop U2 → water penetration diaphragm and source water tank of generation.
And positive electrode is only contacted with the infiltration water of water penetration diaphragm, i.e. positive electrode is close to water penetration diaphragm, such water electrolysis
When liberation of hydrogen, oxygen evolution reaction generation gas easily enter in the water passage of permeable micropore and in the water in water passage
Bubble is generated, bubble is easy to crush so as to generate in the narrow environment in the water passage of the permeable micropore of water penetration diaphragm
Localized hyperthermia's high pressure, and then efficient water body plasma discharge is inspired with minimum voltage, in water penetration diaphragm and water penetration
The plasma of hydroxyl free base class transient state oxidation factor is generated in the water of diaphragm neighboring area（Plasma be with solid-state, liquid,
Gaseous state is in the 4th state of substance of same level, and low temperature plasma is rich in electronics, ion, free radical and excited state molecule, electricity
Son has very high reactivity with ion, and the chemical reaction being difficult under usual conditions or speed is difficult can be made to become very
Rapidly, it is discharged by water body and generates plasma group, the degradation efficiency of pollutant in water body can be greatly improved）, the hydroxyl free
The oxidisability of base transient state oxidation factor is extremely strong（More than ozone）, while existence time in water is again extremely short, therefore can produce
Rapidly to Organic substance in water after life（Such as bacterium）Pollutants is waited to be formed after extremely strong degradation and itself rapid oxidation directly also
Originally it was water, and did not stayed any toxic side effect.
In the use of the present invention, source water carries out electrochemical treatments, inactivation of bacterial, depth degradation through the electrolysis cells first
The major pollutants such as the organic matter in the water of removal source, the porosity sorbing material further carry out the water after electrochemical treatments
Coarse filtration is handled, and most filters out residual harmful substance in water through the further physics interception of the reverse osmosis membrane processing unit afterwards, and
Also filter out in the electrolysis cells course of work there may be cause Biological indicators be deteriorated secondary substance, i.e., the present invention use
The combination of " preposition electrochemical treatments and physical absorption-membrane filtration postpositive disposal ", so as to overcome in background technology, " physics is inhaled
The various defects of the combination of the preposition processing of attached-membrane filtration and electrolysis water unit postpositive disposal "（For example mention in the prior art
The easy broken invalid of filter membrane, heavy metals exceeding standard etc.）, obtain required pure water.Anti-seepage membrane processing unit is pure in the present invention
Physical treatment mode, it is ensured that the tight security of effluent quality especially Biological indicators, and the pollutant in source water of the present invention
Basic handling is clean before reverse osmosis membrane processing unit is entered, therefore the live load of reverse osmosis membrane processing unit is significantly
Mitigate, correspondingly, the service life of reverse osmosis membrane processing unit greatly prolongs.
Existing reverse osmosis membrane determines that must have concentrated water discharge could work normally, and product water by its working mechanism
3 are generally with the ratio of concentrated water:7 or so.But the concentrated water side water outlet of reverse osmosis membrane processing unit is not directly discarded in the present invention,
But it flows back into the water tank of source and makees after-treatment with recycling.For entire water purification machine, what real outer waste discharge was abandoned is only
The minute quantity sewage discharged on the outside of from source water tank.The model machine of the present invention in several typical urbans of China, is provided from respectively with working as districts and cities
Water is source water, makees for a long time, a large amount of post-installation review experimental datas show ensureing the reliable and stable work of system and water outlet water
Under the premise of matter purification safety index, it can control and realize that the ratio of product pure water and efflux wastewater is better than 8:2.With DaLian, China
For area（City supplies the TDS of tap water in 100 ~ 150mg/L）, practical product pure water and waste water ratio are more than 9:1.Therefore,
Wastewater discharge in the present invention is few, and water outlet efficiency greatly improves.
In addition especially, it should be noted that, the product water slant acidity of traditional reverse osmosis purified water system, and the present invention benefit
In the introducing of electrolysis cells, product water tends to alkalescent, and oxidation-reduction potential is relatively low（Less than zero millivolt）, it is good for health to support
It is raw.
Preferably, the pore size of the permeable micropore of the water penetration diaphragm and shape are essentially identical.
In the present invention, if the aperture of the permeable micropore of water penetration diaphragm is excessive（I.e. water passage is excessive）It is equivalent to covert
Increase electrode diameter（Electrode curvature radius）Discharge in water starting excitation voltage is caused to increase, and become generation bubble volume
Reduce the catalytic specific surface area of gas-liquid two-phase greatly.The aperture of permeable micropore is too small（I.e. water passage is too small）, electricity can be made
Solution aerogenesis cannot be introduced into the permeable aperture of micropore（Also bubble can not be just generated in water passage）, so as to make plasma discharge without
Method is normally carried out.Therefore, by the repetition test of inventor, the aperture of the permeable micropore of the water penetration diaphragm is less than 2 millimeters
And more than 1 nanometer, difference is less than 20% to the aperture size of the permeable micropore of the water penetration diaphragm each other between each other.
Preferably, the water penetration diaphragm is hydrophilic water penetration diaphragm.Hydrophilic film surface can form hydrogen bond with water
Ordered structure can improve fenestra water-filling wet face state, and the plasma discharge process in film that is conducive to persistently carries out.
In addition, since water penetration diaphragm obtains the clamping protection of paired electrode, experiment proves that the water penetration diaphragm is using
It will not be scrapped in the process because of premature failures such as damaged or obstructions, remain reliable and stable working condition；Even if water penetration every
It is also scum loosely, therefore suitably switched in electrolytic process and be applied to water penetration diaphragm that film and electrode surface, which occasionally have fouling,
The decomposition voltage polarity of the paired electrode of both sides, it is possible to easily remove anions and canons precipitate in electrode and water penetration
The deposition fouling of membrane surface.
Being further improved for above-mentioned technical proposal be：The outside of the source water tank is equipped with the housing of encirclement source water tank lower part,
The enclosure space for surrounding positive electrode is formed between the housing, source water tank and water penetration diaphragm, the top of the housing, which is equipped with, opens
Mouthful, described be open forms the first water inlet of the source water tank；The bottom of the housing is equipped with the first sewage draining exit.
In this way, enclosure space is injected, and by being set under tap water pressure for water supply water from the first water inlet by city
Water penetration diaphragm between housing and source water tank enters source water tank.Various pollutants in the water of source are obstructed by water penetration diaphragm to be filtered
Until after source water tank fills water, open the first sewage draining exit and keep appropriate aperture, and start electrolytic process.In the water tank of source in water
Ion（Both include original ion being dissolved in the water of source, also include the ion product to water electrolysis）Selectively from water penetration
It is appeared on the inside of diaphragm and enters enclosure space on the outside of film, and be discharged with the infiltration of water penetration diaphragm, the first blowdown from bottom
Mouth discharge, so as to which the water quality in the water tank of source be made to be continuously available purification.
Preferably, the electrolysis power is that the direct current pulse power source of high level narrow spaces or forward voltage level are more than reversely
The component pulse-changing power of voltage level.Electrolytic efficiency can be improved in this way.
Being further improved for above-mentioned technical proposal be：It is equipped with and protects between first water outlet and reverse osmosis membrane processing unit
Pacify filter, the filter core of the cartridge filter is worked with cross-current flow；The cartridge filter is equipped with third water inlet, second
Water outlet and waste, the third water inlet are connected with the first water outlet, and second water outlet and the second water inlet connect
Logical, the waste is connected with source water tank；It is useless that first is serially connected between the waste of the cartridge filter and source water tank
Water ratio, first waste water ratio are formed in parallel by the first solenoid valve and first throttle valve.The filter core of cartridge filter in the present invention
It is preferred that ultrafiltration membrane or microfiltration membranes substitute the microstraining core that tradition uses, rear class reverse osmosis membrane processing unit can not only be formed in this way
More preferable protection, and avoid the frequent replacement of filter core.Actual test proves that apparatus of the present invention are after specified total water production is reached
The filter core of cartridge filter is not decreased obviously still in kilter, water-flowing amount.The waste of the cartridge filter with
The first waste water ratio is serially connected between the water tank of source, the solenoid valve of the first waste water ratio can be made to open so as to right before actually water processed in this way
The filter core of cartridge filter is also rinsed, and can greatly prolong the working life of the filter core of cartridge filter.
Being further improved for above-mentioned technical proposal be：Between the concentrated water outlet of the reverse osmosis membrane processing unit and source water tank
The second waste water ratio is serially connected with, second waste water ratio is formed in parallel by second solenoid valve and second throttle.By opening second
The solenoid valve of waste water ratio can utilize the water purification of cartridge filter to export（That is the water outlet of the second water outlet）To reverse osmosis membrane processing
The reverse osmosis membrane surface of unit is rinsed, and removing is attached to film surface deposit.
In order to improve at least two pairs of the electrolytic efficiency in apparatus of the present invention, the pairs of negative electrode and positive electrode, institute
It states between the negative electrode that porosity sorbing material is filled in the water tank of source.
Porous adsorbing material mainly plays suction-operated in the present invention, since porous adsorbing material is protected by electrolysis cells
Shield has certain self-cleaning palingenesis；Especially activated carbon filled layer or multilayer activated carbon are preferably used in porous adsorbing material
In the case of fiber superposition block, influenced by electrolytic flocculation and the hardened situation of fouling is alleviated significantly, only need to periodically take out cleaning, you can
