Description
Technical field
This utility model is related to the on-line checking of water quality and the early warning failure device of purifier.
Background technology
China's earth's surface drinking water source is mainly river, lake and reservoir.Many local earth's surface drinking water sources are long-term
For III ~ IV class water body, sometimes even do not reach IV class water quality.According to the water quality research to 46 main cities of China, China drinks
Fully up to expectations with water water quality condition difficulty, not up to standard situation, wherein Shanghai inspection often occur more particularly to organic index
Go out Organic substance kind more than 700, Tianjin detects Organic substance kind more than 200, even also there are 50 gas chromatographies the preferable Beijing of water quality.To the greatest extent
Pipe tradition drinking water treatment technology can ensure drinking water quality to a certain extent, but it can not remove water source effectively
Trace soluble organic pollution in water, and can produce during the Chlorination Process in traditional drinking water treatment technology again
Raw many halogenated organic matters.
Organic substance health risk assessment shows：Some toxic organicses have endocrine disrupting, carcinogenic, teratogenesis,
Mutagenic action although in general toxic organicses content is less in water body, but due to its have refractory organicses and
Biological easily accumulation property, Long Term Contact can threaten life and the health of people.
Traditional water purifier does not generally have and shows and change prompt facility based on the filter element/membrane lifetime of effluent quality, uses
Family cannot understand the service condition of filter element/film in time, causes the blocking of filter element/film or the decline of water quality or even secondary pollution.Closely
Ji Nianyou manufacturer proposes a kind of water purifier with filter element/film replacing prompt facility, all kinds of in the market organic for processing
Filter element/the membrane lifetime of thing mainly has three kinds of determination methods.The first sets use time, during the use that simply businessman directly gives
Between reference value often very limited, do not consider the water quality of practical situation and the real-time purifying water effect of water purifier, may go out
Existing water quality is exceeded but does not change filter element/film, or filter element/film does not also puncture just prompting and changes wasting situation.Its
Two is that the water yield processing is counted, with this estimated life, this kind of method still inadequate science, and still do not account for water quality
Actual state, with according to the time change filter element/film there is no essential distinction, equally not scientific and reasonable.Its three be by measure
Electrical conductivity etc. is assessing the dissolvability solid amount in water body（TDS）, or TDS in water, Ci Zhongfang is detected by TDS probe
Although method has accomplished real-time monitoring, selected index TDS refers to the total amount of whole solutes in water, including Organic substance and inorganic
The content of both things, in natural water body, content of organics is less, and this index of TDS can only be used as rough detection can not
The exceeded situation of Organic substance effectively in reflection water body.
The water quality online measuring technique method commonly used at present mainly has chemical method, chromatography, bioanalysises etc..Wherein chemical method
Simulation laboratory's manual analyses process, measurement is accurately, applied widely, but chemical method depends on chemical reaction, there is pre- place
Manage complexity, consume reagent, easily cause secondary pollution problems.Chromatography adopts chromatographic separation technology, and analysis precision is high, repeated
Good, can be used for micro or even organic micro-pollutant detection, but apparatus expensive, complex procedures, test period are long, particularly exist
It is difficult to play a role in the unstable water sample of complicated components, water quality.Bioanalysises are based on microbial reaction, immunological response, enzymatic
Reaction etc., has the advantages that low cost, high selectivity, broad covered area, but its detection process sensor is produced not with test substance
Reversible biochemical reaction, so that the sensitivity decrease of sensor, short life, needs to regularly replace, and bioanalysises exist
The danger of bacteria breed.Fluorescent spectrometry sends longer wavelength light using material after the irradiation of shorter-wavelength light（Fluorescence）'s
Phenomenon carries out elemental analysis, as new water quality detection means in recent years, has that sensitivity is high, selectivity is good, quick, institute
The advantages of need sample few.But there is scattered light interference problem so as to be difficult to be suitable for the complexity long continuous detecting of water quality.

Configure the organic mixed solution such as certain density humic acidss, fulvic acid, aminoacid in laboratory, and adopt in market
Purchase a Water warfare active carbon filter core, the method being provided using this utility model, carry out water quality in the downstream of Water warfare filter element
On-line testing, has directly tested launching light（Fluorescence）Intensity versus time curve is as shown in Figure 2.Can from figure
Arrive, in testing time 50h, filter element is normal operating conditions, and fluorescence intensity significant change, substantially remains in 450 left
Right.Testing time 50-60h fluorescence intensity begin with obvious rise it is believed that the clean-up effect of filter element not exclusively,
It declines to organic adsorption, and filter element starts to lose efficacy.After being about 110h between when tested, fluorescence intensity rises to
About maximum and tend towards stability, fluorescence intensity now is about 2100, the organic fluorescence with the raw water processing without filter element
, it is believed that now purifying filter element complete failure, that is, filter element is breakdown for similar intensity.Therefore, we can be by single
Piece machine sets a certain numerical value between normal work and between puncturing for the fluorescence intensity as early warning value（If fluorescence intensity is 1500）, reach
Then proceed by filter element to this value device and puncture early warning, point out to take the related measures such as replacing filter element.
