Description
Technical field
This utility model relates to a kind of circulating desk type water dispenser, belongs to drinking water terminal water treatment technical field.
Background technology
Currently, water environment is exacerbated, drinking water quality safe and sanitary Frequent Accidents, the most seriously jeopardizes the existence of people.Water pollutes the pollutant mainly produced by mankind's activity to be caused, and it includes industrial pollution source, agricultural pollution source and domestic pollution source three parts.Increasingly the water aggravated pollutes, and the living safety of the mankind is constituted significant threat, becomes the major obstacles of human health, economy and social sustainable development.Investigating according to authoritative institution of the world, annual at least cause global 200d 00,000 people dead because drinking unhygienic water, therefore, water pollution is referred to as " world's number one killer ".
Domestic and international most of waterworks the most still uses the outmoded process of precipitation, filtration, chlorination, and river or subsoil water are simply processed into drinkable water.But, in the face of trade effluent, rural sewage and sanitary sewage wildness are spread unchecked and poured in life water source, waterworks can't bear the heavy load helpless.Adding tap water and arrive, through water transfer pipe network and high-rise storage tank, the additional pollution that drinking water terminal is brought from water factory, municipal tap water dare not say it is health.Especially, although tap water chlorination can effectively kill except pathogenic bacteria, but also can produce 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 goes, and the carcinogens such as nitrite and chloroform also can be made to increase.That is, even if the safety coefficient of drinking water is also the highest.
Existing purification of water quality product or drinking water related product, predominantly medium adsorb or use the filter membrane in various aperture that the nuisance in water is intercepted the physics mode process technique filtered.Owing to activated carbon class adsorbing material is easy to saturated inefficacy, and various filter membrane is easy to be contaminated by bacterial or Organic substance blocks or damaged, and therefore practical situation is can not accomplish water pollutant as desired by Design Theory sufficiently cleaned up.In the face of the most serious source water pollutes, existing physics mode processes technique and the most far from can guarantee that water quality reaching standard.But physics mode water treatment technology also has an advantage in that, it is simply that toxic byproduct will not be generated.The water quality that the most traditional RO membrane reverse osmosis filter method produces is the safest, but then it is up to the most more converse dense water of 40%-70% by exchanged for the cost that ensures safety be wasted and enter sewer pipe, cause huge water resource and waste of energy, and the cost changed after the blocking of RO film is the highest.For reducing or even reaching no effuent discharge, saving water resource, have been developed that various patented technology so far.Such as, converse dense water is stored it use, or the pollutant in dense water are first filtered Posterior circle reuse through molecular sieve etc., or adjust waste water ratio, or reduce cleaning blowing time by electrical control, or dilute in non-return valve is directly returned from water main line, or with " the double water of double films " pattern, water quality based water utilization, etc..The common deficiency of these technology, one is not consider from overall system design, and simply the single measure in local, often makes system overall work unbalance；It two is all not consider that the water inlet operating mode from improving membrane component is started with, and alleviates the workload of membrane component, it may be said that be " curing the symptoms, not the disease ", so the product that yet there are no real utility goods so far comes out.
Comparatively speaking, although Water Treatment technique has the plurality of advantages such as the most efficient, it it is a kind of excellent advanced oxidation processes, but itself there is series of problems in electrochemical treatments, occasion should not be processed at civilian terminal Drinking Water to be used alone, there is not yet so far and close extensively application at daily life Large Water Treatment Field.Tracing it to its cause, one is that Water Treatment technique needs the enough response time, and in daily life water occasion, water purifier is from start to the water outlet only several seconds, and pollutant time of staying in water purifier is the shortest, has had little time related chemistry reaction treatment at all；It two is that Water Treatment technique is likely with certain toxic and side effects.Such as, although chemical oxidation reaction technique can potent inactivation of bacterial, depth degradation Organic substance, remove the various harmful substances in water, but all kinds of Strong oxdiative factors that chemical oxidization method is generated are substantially non-selectivity, uncontrollable, producing, if dealing with improperly, the novel substance not having in the water of source most probably, jeopardizing safe drinking water on the contrary；Just because of this, processing occasion at common people's daily life drink water purifying, the application for Water Treatment technique can be described as double cautious.
But, in today that the unprecedented severe contamination of water environment, conventional physical water purifier are the most unable to do what one wishes, again the probability that Water Treatment is applied is paid close attention in close examination in Drinking Water purified treatment, it is ensured that people's life drinking water quality safety, is of great practical significance.
