Description
Technical field
The present invention relates to the monitoring water quality on line in end water purification field and ultraviolet-sterilization technologies, and in particular to one kind is based on deep
The end water purification component and its fluorescence signal calibration side that there is water quality monitoring with sterilize dual function of ultraviolet LED solid state light emitter
Method.
Background technology
Dissolved organic matter (DOM) in the presence of natural water, main includes high molecular weight protein class, intermediate molecular weight
Humic acid, fulvic acid and other small-molecule substances, the presence of DOM seriously affect coagulation, membrane filtration, advanced oxidation and ion and hand over
The treatment effect with techniques such as absorption is changed, and influences the micropollutants in heavy metal, medicine, personal care articles etc. in water process work
Conversion in skill, in addition, DOM is the important presoma of disinfection by-products generation during chlorination.Therefore, DOM becomes each
The emphasis of class municipal water supply treatment process and end water purification technology removes object.
There are larger differences for dissolved organic matter content in the drinking water resource of various regions；Dissolubility in ChangJiang River drinking water source
Organic carbon (DOC) is usually less than 2mg/L, and North Jiangsu Area drinking water resource is often in 5mg/L or so or even individual drinking water sources
Ground DOC is up to 9mg/L.Coagulation-precipitation-filtering-sterilization process that drinking water plant generally uses at present, mainly to therein big
The realization of molecular weight protein substance effectively removes, and then not satisfactory to intermediate molecular weight humus material removal rate, is disappearing
In malicious technique, Continuous sterilization Disinfection Effect is mainly kept in the form of adding Active Chlorine (liquid chlorine or sodium hypochlorite).However by
In the presence of remaining DOM, chlorination is more, then can generate more disinfection by-products；And chlorination is insufficient, then bactericidal effect is poor,
It is easy to form the diauxic growth of pathogen during pipeline water delivery.
End water purification technology becomes the active demand of drinking water safety guarantee.In recent years, Chinese end water purification industry development
It is very rapid, form a series of water purifier brands.The water purification mode that current end purifier mainly uses includes：(1)
PP cottons are filtered, it is therefore intended that removal turbidity and particulate matter；(2) activated carbon filters, it is therefore intended that absorbed portion organic matter and a huge sum of money
Belong to；(3) membrane material filters, preliminary removal smaller particulate matter and turbidity, including pathogen, and to subsequent nano-filtration film or reverse osmosis
Film plays a protective role, and NF membrane or reverse osmosis membrane then effectively remove most of dissolved organic matter and heavy metal realization.
End water purification market segment competition, increase end water purification product additional function, be conducive to improve brand value and
Added value of product.Wherein monitoring water quality on line and end ultraviolet-sterilization functional unit become end purifier leading manufacturer
The focus of attention.
Current water purifier mainly uses the metrics evaluation water quality monitoring of total dissolved solid (TDS) as a result, however harmful
Heavy metal due to concentration it is relatively low, be generally difficult to be reflected by TDS indexs.Therefore, the on-line monitoring of DOM can be used as end net
The important evaluation index of water water quality.On the one hand, the heavy metal ion in water is dissolved property organic matter especially humus group mostly
Divide and is complexed；On the other hand, how much DOM concentration can reflect the concentration level of disinfection by-products in tap water；In addition, dissolving
Property organic matter and medical nursing product and disinfection by-products present in toxic pollutant etc. during activated carbon filtering and membrane filtration
There are similar removal behaviors.Therefore, by monitoring the removal degree of dissolved organic matter, it can theoretically reflect a huge sum of money simultaneously
Belong to, the removal level of toxic micropollutants present in medical nursing product and disinfection by-products.Water purification product in end supervises water quality
The requirement of survey technology is that needs are small, energy consumption cost is low, pollution-free and sensitive quick.
For end ultraviolet-sterilization, the potential microbial contamination of water purifier pipeline and water tank institute can be prevented, as last
Ensure process.The mode mainly taken at present is according to user's different quality, water demand setting bypass or water tank.Through inspection
Rope, the prior art have issued for relevant technical solution, and such as Chinese Patent Application No. CN201510129157.9, publication date is
2015.06.17 application case discloses a kind of tap and purifier, and this application is using ultraviolet lamp as ultraviolet source
Ultraviolet sterilization apparatus carries out sterilizing, however is pointed out that in ultraviolet lamp and contains mercury vapour, if in water purification product
Middle extensive application, recycling disposal is improper will to cause very important problem of environmental pollution.It comes into force within 16th in August in 2017《It closes
In the Minamata pact of mercury》It is also proposed that claimed below：Contracting party including China rises in the year two thousand twenty, forbids producing and import and export
Mercurous product.
Light emitting diode (LED) has many advantages, such as that monochromaticjty is good, small, low energy consumption and long lifespan, and its emission wavelength
Deep ultraviolet band (wavelength is less than 300nm) is extended to by visible light wave range, the development of deep ultraviolet band LED in recent years is dashed forward
It is broken, have commercialization mass production ability.Such as Chinese Patent Application No. CN201410502662.9, publication date is
2014.12.10 application case discloses a kind of using LED light emitting diodes as the Ultraluminescence dual signal water monitoring device of light source
And its application process, Chinese Patent Application No. CN201510738667.6, publication date are that the application case of 2017.10.17 discloses
It is a kind of to be all made of by the three signal water quality sensor of Ultraluminescence and application, above-mentioned two application case of light source of single UV-LED
Using ultraviolet LED as light source, using in light path relative position photodiode detect ultraviolet light absorption angle value, and using with it is ultraviolet
The bandpass filter and photodiode of LED light path upright position detect two kinds of fluorescence signals of protide and Humus.It is above-mentioned
Application case can ensure the water quality monitoring in water treatment procedure, using LED module carry out sterilizing, however its there is also certain
Defect：1) its monitoring water quality on line module and ultraviolet-sterilization function module are all made of sonde-type design or flow cell design, such
Design is larger for the difficulty being integrated into water purifier pipeline mainly for water treatment plant or the on-line monitoring of water environment；2) single
A LED light source need to use collector lens to collapse light emitting anger, be encapsulated with TO39, required of high cost, and LED light source irradiation range compared with
Small, Disinfection Effect is poor；3) since fluorescence signal is nondimensional free unit, calibration is not carried out to it and is difficult to ensure detection knot
The accuracy of fruit.
Defect based on the prior art, there is an urgent need for developing, a kind of cost suitable for end purifier is low, integrated level is high, water
The end water purification component of quality detection and good sterilization effect.
