Description
Technical field
The present invention relates to store the fresh-keeping method and apparatus of tap water in the water tank, relate in particular to and store the fresh-keeping method and apparatus of tap water in the water tank before tap water is produced the back dispensing.
Background technology
The Along with people's growth in the living standard is more and more paid close attention to the health problem of Drinking Water, to the also progressively lifting of requirement of Drinking Water.Present stage, a lot of areas utilized reuse technology, through handle one slightly pollutant effluents obtain Drinking Water.Drinking Water is stored in after producing in the water tank, delivers to as tap water and respectively uses water spot.Tap water stops because of long-term in storage process, easy breed bacteria, and rich oxygen level is lower, does not satisfy the health standards of tap water.
Summary of the invention
The objective of the invention is to provides a kind of fresh-keeping method and apparatus of tap water in the water tank of storing to deficiency of the prior art.This method and apparatus can solve the long time stored breed bacteria of tap water, and the problem of water quality variation continues sterilization to tap water, for people improve health, stable tap water.
In order to solve the problems of the technologies described above, the present invention is able to solve through following technical proposals:
Store the fresh-keeping method of tap water in the water tank, may further comprise the steps successively:
A. tap water is extracted out from store water tank;
B. pump into jet mixer again, simultaneously through ozonizer to the jet mixer delivery of ozone, the sterilization that carries out disinfection of ozone and tap water thorough mixing;
C. the water outlet of jet mixer is removed granule foreign and bacterium corpse through graded filter;
D. the water outlet of the graded filter ultraviolet sterilizer of flowing through, ultraviolet ray is carried out sterilization to tap water, and the unreacted portion ozone that will be dissolved in the water is transformed into oxygen, and all the other ozone resolve into oxygen in time gradually, increase water oxygen level;
E. the effluent recycling of ultraviolet sterilizer is to storing water tank.
Tap water is extracted out flow through successively outside jet mixer, graded filter, ultraviolet sterilizer from water tank.Ozone and ultraviolet being used in combination; Can be effectively to the water of storing in the water tank carry out disinfection, sterilization; And the corpse through impurity in the graded filter filtering water and bacterium; Simultaneously be transformed into oxygen by the ultraviolet ray unreacted portion ozone that will be dissolved in the water, all the other ozone resolve into oxygen in time gradually, increase the oxygen level in the water.
Among the step a, tap water is extracted out from store water tank, germicidal treatment again carries out disinfection.Disinfection sterilizing device is located at outside the water tank, can not reduce the water space of water tank, the disadvantageous effect of also having avoided the disinfection sterilizing device running to bring to tap water, the water that can also guarantee each corner in the bulky storage water tank sterilization that can both be sterilized.
Among the step b, under the effect of high velocity jet, make in the jet mixer air cavity and form negative pressure, suck ozone, high velocity jet is ground into tiny bubble to ozone gas again, makes itself and water fully contact mixing and carries out disinfection.After ozonize, sterilization, sterilize, go flavor, prevent the generation of carcinogenic substance trichloromethane, increase water oxygen level, be desirable purified tap water.
Among the step c, graded filter can be removed granule foreign and bacterium corpse.
In the steps d, ultraviolet sterilizer carries out sterilization to tap water on the one hand, and the unreacted portion ozone that will be dissolved in the water on the other hand is transformed into oxygen, and all the other ozone resolve into oxygen in time gradually, increases the oxygen level in the water.Water behind ozonization can not be drunk immediately, and existing terms of settlement is placed for some time exactly and treated just can drink after it decomposes.The present invention destroys the part residual ozone through ultraviolet ray can make tap water output more flexible.
Among the step e, the water after the ultraviolet sterilizer sterilization is back to be stored in the water tank, plays the effect of circulation sterilization fresh-keeping like this, for the user provides healthy, fresh tap water.
As preferably, at the water low peak period, step a-e is carried out in circulation.At the water low peak period, the water above-mentioned steps that can repeatedly circulate in the water tank.Repeatedly circulation can make water quality improve, and total number of bacterial colony reduces, and water oxygen level increases.Water just often, water can in time be extracted out in the water tank, can repeatedly circulate.
As preferably, the dosage of ozone is 0.2-0.4mg/L.The dosage of ozone confirms according to discharge and condition of water quality, water quality better then the ozone dosage can reduce, the relatively poor then ozone of water quality dosage strengthens in right amount, it is better to remain on 0.2-0.4mg/L.For example, discharge is 10m
3/ hour, when water quality was better, the addition of ozone was 0.2mg/L; Discharge is 10m
3/ hour, when water quality was relatively poor, the addition of ozone was 0.4mg/L.Judgement about above-mentioned water quality good job: specific conductivity should be less than 50 μ s/cm in the general provision direct-drinking water; A conductivity table can be installed before ozonizer; If specific conductivity thinks then that at 0-10 μ s/cm water quality is fine,, specific conductivity needs water quality inferiority to improve if then thinking at 10-50 μ s/cm.
As preferably, the filtering accuracy of said graded filter is not less than 0.22 μ m.The filtering accuracy of graded filter can effectively be removed granule foreign and bacterium corpse during greater than 0.22 μ m.
As preferably, said ultraviolet wavelength is 254nm.Selecting wavelength is the uv lamp of 254nm, can efficient sterilizing, can the unreacted ozone of part in the water be transformed into oxygen again.
Store the fresh-keeping device of tap water in the water tank; Comprise being arranged at and store the outside circulation line of water tank; Said circulation line is provided with from feed-water end to water side successively: water circulating pump, jet mixer, graded filter and ultraviolet sterilizer, said jet mixer links to each other with ozonizer.
According to technical scheme of the present invention; Ozone and ultraviolet being used in combination; Can be effectively to the water of storing in the water tank carry out disinfection, sterilization, and the corpse through impurity in the graded filter filtering water and bacterium is transformed into oxygen by the ultraviolet ray unreacted portion ozone that will be dissolved in the water simultaneously; All the other ozone resolve into oxygen in time gradually, increase the oxygen level in the water.For the user provides healthy, fresh tap water.
