Description
Technical field
This utility model relates to a kind of Portable drinking water treatment facilities, belongs to the water quality advanced processing technology field of Drinking Water.
Background technology
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 ".Currently, water environment is exacerbated, seriously threat to life continuity, especially when burst natural and man-made calamities more so.The most poor and backward area, drink to clean relieved water is the most luxurious for general public.If the common people can be made all can to drink clean relieved water with means simple, cheap, efficient, when for the most immeasurable beneficence！
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.
Since directly drinking public water supply is difficult to ensure that safety, water purifier are arisen at the historic moment, become common people's hard requirement.But, existing with city for tap water be source water purification of water quality product or drinking water related product, essentially medium absorption or use various bore filter film that water pollutant is intercepted the physical treatment technology 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 with medium absorption or use various bore filter film that water pollutant is intercepted the physics mode water treatment technology filtered the most far to can guarantee that water quality reaching standard.It addition, traditional RO membrane reverse osmosis filter method is very serious to the waste of water resource, often purifies 1 liter of pure water and be accomplished by discharging 3 liters of concentration waste water.But, physics mode water treatment technology also has its points of course: generally do not generate toxic byproduct.
Comparatively speaking, though Water Treatment technique has the plurality of advantages such as the most efficient, and it is unsuitable for civilian terminal Drinking Water field.Trace it to its cause, one is that Water Treatment technique needs enough response time, and in daily life water occasion, and water purifier is from start water inlet to water outlet only several seconds or even shorter, 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 generally with certain toxic and side effects.Such as, although chemical oxidation reaction 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, generating, if dealing with improperly, the novel substance even strong carcinogen not having in the water of source most probably, jeopardizing safe drinking water on the contrary.And reduction reaction controls the improper Similar Problems that also brings along, such as nitrate and may be converted into strong carcinogen nitrite；Just because of this, have no so far in the drinking-water terminal popularization and application of Drinking Water purified treatment field especially family.
Fortunately, in daily life, drinking water needs often has at times, the feature of interval.Such as, family's three meals water and bathing peak are concentrated mainly on time morning, noon and afternoon；Wash water is then by week/time calculating.Daily life is drunk water storage apparatus, logical refers to the drinking water terminal with storage tank (tank, container), such as: 1) pipeline water cleaning systems end wall on-hook, desk-top or vertical drinking；2) RO water purification machine water outlet pressure store bucket (case), and watered glass for drinking, kettle；3) elevated tank that public supply mains skyscraper top layer is installed, even urban residents' groundwater abstraction are to the water tank on roof.The common problem that at present such system exists is that in water, bacterial micro-organism exceeds standard in storage tank, has a strong impact on water quality even abnormal flavour smelly.The solution that there is no so far.
Meanwhile, it has been found that existing bottled water is widely used, when needing to access tap water after bottled water is opened relatively for a long time or bottled water finishes off, there is no existing equipment.Therefore, be badly in need of developing a kind of be convenient for carrying and disclosure satisfy that the drinking-water deep purifying requirement of municipal tap water terminal, with water bottle as reaction tank, source water is processed, Portable drinking water treatment facilities that every household is all afforded to use.
