Description
Technical field
The present invention relates to a kind of water dispenser and method for disinfection thereof with sterilizing function.
Background technology
As everyone knows, the air that the negative pressure that produces after the bottled water water outlet on the water dispenser will lean on non-sterile to handle replenishes, and entrained air bacterium and dust enters water dispenser, causes " secondary pollution ", also can in water dispenser, form the clammy bacterial film of one deck simultaneously, jeopardize safe drinking water.Discover that the bacterium in the water dispenser mainly contains Acinetobacter baumannii, clostridium, coliform, mould, yeast, Pseudomonas aeruginosa etc., must kill for this reason, prevent the growth of pipeline and tank bacterium the bacterium that grows in the pipeline of water dispenser and the tank.
Generally one of purpose of carrying out water treatment is the pathogenic bacterium of killing in the water, and makes the bacteria content standard up to specification in the water.Water treatment method commonly used is chlorine disinfectant, disinfection by ultraviolet light and ozonization.
Chlorine disinfectant is mainly used in the tap water sterilization.
The principle of disinfection by ultraviolet light be the pathogenic micro-organism absorbing wavelength behind the ultraviolet energy between 200nm～275nm, its genetic material (nucleic acid) is undergone mutation and is caused no longer fissiparity of cell, reaches the purpose of disinfection.But one of its shortcoming is that ultraviolet ray is difficult to reach ideal effect because of the penetrativity in water is limited; The 2nd,, uv sterilisation can not be kept sterilisation effect as chlorine disinfection method.And what generally adopt in bottled water and the water dispenser is uv sterilisation.
The principle of ozonization is that redox reaction takes place in water ozone, produce extremely strong antozone (O) and the hydroxyl (OH) of oxidation capacity, organic substance, bacterium and microorganism in the moment water of decomposition, have the oxidation sterilizing ability stronger than chlorine disinfection method, but the improper bromate that might produce carcinogenic danger of ozonation process brings hidden danger to water safety.Also often adopt ozonization in bottled water and the water dispenser.
Another purpose of water treatment is the objectionable impurities of removing in the water, and what it adopted is electrochemical water treating method.Electrochemical water treating method is based on electrochemical ultimate principle, utilize electrode reaction and correlated process thereof, by direct and indirect comprehensive actions such as redox, pollutions such as organism, heavy metal, nitrate, colloid and particle, bacterium, colourity, stink in the water all there is good removal effect.Sewage work often adopts this method to dispose of sewage.Electrochemical sterilization is the oxidizing substance (H that utilizes electrolytic process to produce
2O
2, O
3Hydroxyl radical free radical etc.) to the lethal effect of bacterium, the electrical breakdown effect of electric field cell membrane, electric osmose and electrophoretic action, the adsorption and oxidation performance of electrode pair cell and effect of electric current pair cell or the like comprehensive action of pair cell metabolic function, reach potent germ-resistant purpose jointly.Especially electrochemical lasting bactericidal potency shows than ozone and the stronger sterilizing ability of ultraviolet ray.Another advantage that electrochemical sterilization contrasts other method for disinfection is nontoxic pair of effect, can not cause secondary pollution.
