Description
Technical field：
The invention belongs to photoelectric sensing technical field of measuring equipment, are related to a kind of photoelectric sensing measuring device, using optical filtering
The bandpass filter of different wave length, is placed in the different transparent windows of optical filtering rim of wheel circumference by the structure of wheel and Wavelength tunable light source
In, the function of selection wavelength is realized using the rotation of filter wheel.
Background technology：
With the propulsion of global industry process, the living standard of the mankind is higher and higher, but the environmental problem occurred is further
Seriously, environmental pollution is just drastically influencing the living environment of the mankind and animals and plants.Water quality monitoring is monitoring and measures dirty in water body
Type, the concentration and variation tendency of each pollutant of object are contaminated, the range of the process of evaluating water quality situation, water quality monitoring is very wide
It is general, including be not contaminated and contaminated natural water (river, river, lake, sea and underground water) and various industrial water drainages etc..
The main monitoring project of water quality can be divided into two major classes：One kind be reflect water quality condition overall target, as temperature, coloration, turbidity,
PH value, conductivity, suspended matter, dissolved oxygen, COD and biochemical oxygen demand (BOD) etc.；Another kind of is some noxious materials, as phenol,
Cyanogen, arsenic, lead, chromium, cadmium, mercury and organic agricultural chemicals etc..For the situation of objective appraisal rivers and ocean water quality, above-mentioned monitoring project is removed
Outside, the measurement of progress flow velocity and flow is needed sometimes.Currently, China's water environment water quality monitoring technology achieves the hair of fast speed
Exhibition, water quality monitoring technology mainly based on physics and chemistry monitoring technology, including chemical method, electrochemical process, atomic absorption spectrophotometry,
Ion selective electrode method, the chromatography of ions, gas chromatography, plasma emission spectroscopy (ICP-AES) method etc..Wherein, ion
Selecting electrode method (qualitative, quantitative), chemical method (gravimetric method, volumetric precipitation method and spectrophotometry), at home and abroad water quality routine is supervised
It is generally used in survey.Biological monitoring in recent years, remote sensing monitoring technology have been also applied in water quality monitoring.
Traditional physics and chemistry monitoring：In surface water quality monitoring, since monitoring instrument is fairly simple, physical monitoring achievement data
It is often easier to obtain, common physical index monitoring instrument has the transmissometer for measuring water turbidity, measures the filter used in coloration
Light photometer measures conductivity conductivity meter etc., and also multi-functional water quality monitor realizes while measuring multinomial physics
The effect of index.The monitoring of chemical index is the emphasis of earth's surface water monitoring, as country is to the weight of toxic organic compound pollution monitoring
Depending on, instrument cause and research and development in terms of achieve certain progress, some monitoring stations have had been introduced by large and medium-sized laboratory prison
Instrument is surveyed, it can heavy metals and halogen, ammonium nitrogen, nitrite nitrogen, cyanide, the phenol such as field monitoring Zn, Fe, Pb, Cd, Hg, Mn
The substances such as class, anionic detergent and Se.
Biological monitoring：Biological monitoring is one of water environment pollution monitoring method, it is to utilize bion, population or group
Reaction caused by environmental pollution variation illustrates the pollution situation of environment, has sensibility, enriching, chronicity and comprehensive
The features such as.The Bio-monitoring method applied in actual monitoring at present mainly refers to including biotic index method, specific diversity
Number method, microbial community monitoring method, biological toxicity test, biological residual hazard measure, ecology manages malicious method etc., the water being related to
Raw biology covers unicellular alga, protist, benthon, fish and amphibian animal.
Remote sensing monitoring technology：Inland Water Remote Sensing Techniques in Determining Water Quality is the spectrum based on experience, statistical analysis or water quality parameter
Characteristic, selection remote sensing wave band data and ground actual measurement water quality parameter data carry out mathematical analysis, establish water quality parameter inversion algorithm
It realizes.Remote Sensing Techniques in Determining Water Quality method can reflect distribution situation and variation of the water quality on room and time, find some often
The pollution sources and pollutant that rule method is difficult to disclose migrate feature, and with monitoring range is wide, speed is fast, at low cost and be convenient for
The advantage of long-term dynamics monitoring.
Permanganimetric method (potassium permanganate titration) is the oxygen using potassium permanganate as titrant
Change reductometry, in strongly acidic solution, potassium permanganate is strong oxidizer, and solution acidity should be controlled is in 1-2mol/L
Preferably, acidity is too high, and potassium permanganate is easy to decompose；Acidity is too low, and reaction speed is slow, and will produce manganese dioxide precipitate.It adjusts molten
Liquid acidity often uses sulfuric acid.Because nitric acid has oxidisability, should not use.And hydrochloric acid has reproducibility, understands by potassium permanganate oxidation,
It is also not suitable for using.
The principle of potassium dichromate method is the reproducibility object in a certain amount of potassium dichromate oxidation water sample in strongly acidic solution
Matter, excessive potassium bichromate make indicator, with l ferrous ammonium sulfate solution residual titration with ferroin.It is calculated in water sample also according to dosage
The oxygen of immunogenic substance consumption.Acid potassium dichromate oxidation is very strong, and oxidable major part organic matter is added silver sulfate and makees catalyst
When, linear aliphatic compound can be aoxidized completely, and aromatic series organic matter is not easy to be aoxidized, and pyridine is not oxidized, volatilization
Property the organic matters such as linear aliphatic compound, benzene be present in vapor phase, cannot be contacted with oxidant liquid, aoxidize unobvious.Chlorine
Ion can be aoxidized by bichromate, and can be acted on silver sulfate and be generated precipitation.
In the above detection method, permanganimetric method and potassium dichromate method are common water quality detection means, permanganimetric method
Lighter water sample is polluted suitable for measuring, but is easy to be interfered by chlorion；Potassium dichromate method is suitable for measuring seriously polluted
Water sample, but be affected by external environment；That there is minutes is long, complicated for operation for both of which, real-time is poor
The shortcomings that.In recent years, since near-infrared and ultraviolet spectroscopy can analyze detection material composition in real time, (absorption of ultraviolet spectra is brighter
It is aobvious), the detecting system based on spectroscopic methodology, which is just increasingly being, to be widely applied.201610872807.3 disclosure of Chinese patent
