Description
Technical field
The present invention relates to a kind of drinking pure closed cycle supply system and its control method, belong to purifying water process technology
Field.
Background technology
With the fast-developing and growth of China's economy, the various pollutants that all trades and professions are discharged, and automobile is wide
Exhaust emissions produced by general popularization, causes increasingly severe pollution effect to air, food, water needed for human life,
Can only move heaven and earth to tackle the harm produced by various pollutions for the people that survive.In face of the air of severe contamination, state
Family has caused great attention, in order to administer and improving the harm produced by air pollution, takes a series of behave and pays
Huge cost is gone out, has obtained progressively improving.For food be subject to agricultural chemicals, chemical fertilizer, chemical agent, heavy metal, antibiotic and
The harm of various hormone medicines and transgenosis, country similarly pays much attention to, reinforcing management of going into overdrive, and implements
A series of Supervision Measures, being among constantly improve.But the drinking water safety problem in actual life needed for people, mesh
Preceding country does not cause attention degree higher also, lacks specification, supervision and control, and the quality of drinking water exists many dangerous
Sexual factor, has triggered more social concerns and negative effect, therefore, for water safety, people have to take various sides
Formula, such as：Install household water filter, the water intaking of residence district automatically taking water machine, using bottled water or using the modes such as bottled water come
Ensure our daily water consumption safety, but these modes but also there are problems that various.
(1) household water filter is installed
The species of current household water filter has mainly divided into micro-filtration water purifier, ultra-filtration water purifier and anti-penetration water purifier,
Wherein, micro-filtration water purifier uses the water purifier of micro-filter technology, and typically at 1-0.1 microns, common various PP cottons filter filtering accuracy
Core, activated carbon cartridge, ceramic element etc. belong to micro-filtration category, and it mainly carries out simple thick mistake by way of absorption
Filter, the large granular impurity such as silt, iron rust in filter water can also remove chlorine residue, but the bacterium that can not be gone in water removal etc. is harmful
Material.Ultra-filtration water purifier using hyperfiltration technique water purifier, filtering accuracy can only filter the iron in water at 0.1-0.01 microns
The harmful substances such as rust, silt, suspension, colloid, bacterium, larger molecular organicses, and to the removal effect of small molecule organic pollution
Fruit substantially, does not reach the requirement of advanced treating.Anti-penetration water purifier is that domestic. applications are at most also most commonly seen, its construction
Mainly it is made up of three vertically-mounted filter sticks and a horizontally loaded type reverse osmosis unit, first is white PP cotton filter stick (mistakes
10 microns of precision is filtered, effect is：Sticky matter, floccule, particle and the impurity gone in water removal)；Second is dark brown filter stick
(effect is：Decolouring, taste removal, absorption microorganism)；3rd is that (1 micron of filtering accuracy, effect is white PP cottons filter stick：More
The particle and impurity further gone in water removal).Core component in water purifier is that (operating pressure is 3~5bar to reverse osmosis unit
Category low-pressure membrane), the aperture of film is 0.01-0.001 microns (only import reverse osmosis unit can be only achieved the precision), the aperture pair
The clearances such as the harmful components such as arsenic, lead, mercury, chromium, barium, plasma and halogenated hydrocarbons, agricultural chemicals, radioactive particle are up to more than 70%；
And the clearance of domestic reverse osmosis unit can only achieve more than 50%.Water purifier still has certain in initial installing and using
The removal of impurity and catharsis are removed, however it is necessary that being regularly replaced to filter stick and being maintained, use cost is higher, and uses
The impurity and microorganism being filtered in journey are remained among system, and the accumulation of impurity and microorganism causes a large amount of of bacterium
Grow, cause whole system to form bacteria breed station, but without any manually or automatically operating function pair in water purifier system
Three filter sticks carry out automation cleaning, exclude the impurity produced by filtering and microorganism；Also system is entered without any function
The processing method of row high-temp sterilizing and measure, these serious defects are present, and will necessarily cause various filter sticks and anti-
There is hidden trouble in the amount reproduction of the inside and outside bacterium of permeability apparatus, quality of pure water.
(2) residence district automatically taking water machine
The widely available automatically taking water machine of swiping the card for using in residence district, its construction and principle and the complete phase of household water filter
Together, specifications and models and aquifer yield are simply different from, the problems of and hidden danger it is identical.
(3) bottled water
Bottled water is all mostly the water prepared by a little more compact simplified first-stage reverse osmosis devices, uses high pressure counter-infiltration
Device, the water quality of institute's output will produce water quality far above household water filter and residence district automatically taking water machine.But these are small-sized
Simple first-stage reverse osmosis device lacks supervision and control, there is more disadvantage there is presently no unified standard, market confusion
End：The materials such as part 1. used in water generator, instrument and meter, valve and pipeline do not reach foodstuff sanitation-stage requirement, pure
Water purification is vulnerable to pollution；2. the storage of pure water is all the static storage in container or bucket, easy breed bacteria；3. pure water
Storage container and bucket are all mostly plastic containers, and mostly regenerated plastics are made, and are easily caused harmful substance and are released to pure water
In；4. the filtration system and reverse osmosis unit in water generator do not have any mode and measure to carry out high-temp sterilizing, easily
Cause a large amount of breed bacterias of system；Whether 5. purified water bucket is all that circulation is used in turn, every time by strict before filling
Cleaning, disinfect, people cannot understand and confirm, this is also the presence of larger hidden danger to water quality；6. bottled water
Quality additionally depend on the length of filling environment, the length of filling rear storage time, and user's use time, to pure water
Quality can produce more uncertain factor.
Meanwhile, there is no any label to indicate production unit, date of manufacture, the date of production, quality guarantee period on most buckets
Limit, quality standard, production licence, hygiene permits etc. are identified, because these more small-sized simple first-stage reverse osmosis devices are general
Store-through is poor in technical matters backwardness, working condition, without health security measure at all so that the quality of bottled water cannot be guaranteed.
It is that water fakement phenomena also occurs to make people more inapprehensible, and some retailers are driven by interests, production it is so-called pure
Water, in order to not have incrustation scale after allowing people to view to be boiled water with kettle, production process is using the calcium and magnesium softened in resin adsorption water
Ion is good with the quality for proving its water so as to reach the purpose of the boiled rear non-scaling of water；In order to allow people to feel bottled water
It is in good taste, employ in process of production activated carbon decolourized, taste removal, so as to allow people to feel the in good taste of water, this
So-called device for producing pure water is planted, water is squeezed into plastic holding device using a water pump simply and is passed through in activated carbon container i.e.
Calcium ions and magnesium ions suction-operated and decolouring, the effect of taste removal are completed, such production technology does not produce any waste water, simply pays
The point electricity charge and the cost of labour, can not be to the harmful substance in water body (such as：Arsenic, fluorine, lead, barium, aluminium, mercury, chromium plasma with
And halogenated hydrocarbons, agricultural chemicals, heavy metal, antibiotic, radioactive particle etc.) produce any removal effect.
(4) bottled water
Bottled water is typically all to be produced by relatively large enterprise, and usual people contribute to outdoor and travelling drink mostly
With, due to being related to the factors such as cost, it is rare to be cooked as family using bottled water, made tea etc. with water, though and bottled water
So there is certain quality assurance, but still storage condition and shelf life long water produced hidden danger of quality can be subject to.
By to above-mentioned four kinds analyzing as can be seen that the water that various modes are obtained all can various degrees with water
Insecurity and uncertain hidden danger of quality, if having ignored the quality of water, harm of its hidden danger to people is difficult to expect.
The etiologic origin of the mankind is all mostly closely bound up with water, because water has too many insecurity factor, once drink or
Person has drunk the water dealt with improperly for a long time, will trigger various infectiousness, epidemic disease, or even have more fearful disease
Become.Therefore, people must pay much attention to source and the quality of water.
