Description
Technical field
The present invention relates to a kind of circulating desk type water dispensers, 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 forms significant threat to the living safety of the mankind, 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 precipitation, 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.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
Cleaning blowing time or direct through non-return valve is reduced Deng filtering Posterior circle reuse or adjustment waste water ratio or by electrical control
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, simply local single measure, 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 electrochemical treatments should not handle occasion list in itself there are a series of problems 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, from start, to water outlet, only several seconds, pollutant exist water purifier
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, can be described as the application of Water Treatment technique 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, it is ensured that people's life drinking water quality safety has
Highly important realistic meaning.
The content of the invention

The working mechanism of the present invention and the advantageous effect brought are presented below：
Using water penetration membrane as boundary, paired negative electrode and positive electrode set up separately in water penetration membrane two water container of crossing
Side, the negative electrode are being crossed in water container, and the positive electrode is being crossed outside water container.Certainly, cavity is internally provided with as crossed water container,
Water penetration membrane is arranged on cavity housing, then the positive electrode being arranged in cavity, which is considered as, to be arranged on outside water container.
Heretofore described positive electrode is only contacted with crossing in water container by the infiltration water of water penetration membrane（For positive electrode not
Water with crossing water container contacts directly）, anode direct oxidation reaction was transferred to outside water container and was carried out, reaction product of anode exists
Container is drained outside, will not return again to pollution water quality in container.Meanwhile such as chlorine residue, various harmful the moon of the negative pollutant in water
Ion etc. is acted on by positive electricity pole tension, can also out of container in water through water penetration membrane, it is outer with oozing to move to water container
Permeable discharge.
Therefore, the various zwitterions in the water of source are during cell reaction when in use, from crossing in water container through saturating
Aqueous membrane was moved to and exhausted outside water container.And the zwitterion in water is the TDS for forming water（That is dissolvability solid amount）
Principal element, under electrolysis, zwitterion in water is mainly through the interelectrode water penetration membrane of yin, yang with outer waste discharge
Water is discharged, in this way, the TDS for crossing water in water container is just reduced.
The structure of water penetration membrane shows as the water passage region of countless permeable micropores on microcosmic in the present invention, due to
Water penetration membrane 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 relation is formed：Thoroughly
The outer positive electrode of aqueous membrane（+）The voltage drop U1 of moisture film → water penetration membrane direct impedance between → positive electrode and water penetration membrane
Pressure drop U2 → water penetration membrane of generation and the voltage drop U3 for crossing the anti-generation of water resistance between the negative electrode in water container.

In by the way that so as to fulfill cyclic electrolysis, the various zwitterions in water are during cell reaction, from crossing in water container through saturating
Aqueous membrane moved to and was exhausted outside water container, the water quality in water tank is made constantly to be purified.
In the use of the present invention, source water carries out electrochemical treatments, inactivation of bacterial, depth degradation through the electrolysis cells first
Then the major pollutants such as the organic matter in the water of removal source are filtered out in water through the further physics interception of the membrane filter unit and remained
Harmful substance, and also filter out in the electrolysis cells course of work there may be cause Biological indicators be deteriorated secondary substance,
