Description
Technical field
The present invention relates to performance testing device, especially COD of sewage ultraviolet spectra absorption detecting platform.
Background technology
Life and the production activity of the mankind all be unable to do without water, the water taken from nature is contaminated owing to having infiltrated various pollutant, change the physics that natural water is original, chemical or biological composition and character, even lose use value, then outer row is discarded, this water going out of use outer row is referred to as sewage. and sewage is originated by it, sanitary sewage and the big class of trade effluent two can be divided into, in general, the index of inspection sewage has following: COD, BOD, colourity, float, heavy metal etc..
Sewage physics parameter test method the most all uses sensor on-line testing, but owing to sewage contains the highest stickup liquid, have on sensor and be stained with mucus, make sensor lose sensitivity, optic test can be at a high speed, detect in real time the developing direction of sewage discharge performance test.
Currently without sewage performance parameter is carried out optic test tester and method of testing.
Therefore design COD of sewage ultraviolet spectra absorbs testboard, and for grasping its performance parameter, raising cesspool clean-up effect has important meaning.
Summary of the invention
It is an object of the invention to provide a kind of COD of sewage ultraviolet spectra absorption detecting platform, can real-time, efficient detection wastewater parameters.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of COD of sewage ultraviolet spectra absorption detecting platform, including the soil pipe being arranged on the right side of cesspool, the right side of soil pipe is connected with the water inlet of ultraviolet spectra absorption detecting device frame, consolidates with outlet pipe on the right side of ultraviolet spectra absorption detecting device frame；In described ultraviolet spectra absorption detecting device frame successively from one to being arranged with xenon flash light source, grating splitting system, transparent sensing chamber, lens, photoelectric sensor, the output signal of photoelectric sensor passes through filter amplifier, microprocessor, the output signal of described processor is sent to control module, control module controls xenon flash light source, grating splitting system and photoelectric sensor, and the signal of control module delivers to computer.
Described emitter pulse xenon source and grating splitting system, transparent sensing chamber, lens, photoelectric sensor straight line each other are installed, and photoelectric sensor is arranged in the focus of lens.
The exhaust gas channel of described soil pipe composition is mutually perpendicular to arrange with detection light path xenon flash light source, transparent sensing chamber, lens, photoelectric sensor.
The step motor drive that described grating splitting system (13) is controlled by computer (1) rotates, produce monochromatic light, described transparent sensing chamber (10) is circular configuration, and diameter is more than soil pipe (3) and outlet pipe (11) diameter.
Compared with prior art, the invention has the beneficial effects as follows: owing to using technique scheme, can detect the COD parameter of sewage, therefore the present invention reaches the purpose of test sewage performance parameter comprehensive, quick, accurate, and then improves motor vehicle emission performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
In order to make technical scheme become apparent from, below in conjunction with accompanying drawing 1, the present invention is described in detail.It should be appreciated that the detailed description of the invention described in this specification is only used to explain the present invention, it is not intended to limit protection scope of the present invention.
The invention discloses a kind of COD of sewage ultraviolet spectra absorption detecting platform, including the soil pipe 3 being arranged on the right side of cesspool 2, the right side of soil pipe 3 is connected with the water inlet of ultraviolet spectra absorption detecting device frame 4, consolidates with outlet pipe 11 on the right side of ultraviolet spectra absorption detecting device frame 4；In described ultraviolet spectra absorption detecting device frame 3 successively from one to being arranged with xenon flash light source 5, grating splitting system 13, transparent sensing chamber 10, lens 6, photoelectric sensor 7, the output signal of photoelectric sensor 7 passes through filter amplifier 8, microprocessor 9, the output signal of described processor 9 is sent to control module 12, control module 12 controls xenon flash light source 5, grating splitting system 13 and photoelectric sensor 7, and the signal of control module 12 delivers to computer 1.
Described emitter pulse xenon source 5 is installed with photoelectric sensor 7 straight line, and photoelectric sensor 7 is arranged in the focus of lens 6.
The exhaust gas channel of described soil pipe 3 composition is mutually perpendicular to arrange with detection light path xenon flash light source 5, transparent sensing chamber 10, lens 6, photoelectric sensor 7.
The step motor drive that described grating splitting system 13 is controlled by computer 1 rotates, and produces monochromatic light, and described transparent sensing chamber 10 is circular configuration, and diameter is more than soil pipe 3 and outlet pipe 11 diameter.
The work process of the present invention is: control module 12 is controlled by upper PCs 1, by the soil pipe 3 after cesspool 2, sewage is accessed in ultraviolet spectra absorption detecting device, measure in sewage content in COD, data are uploaded to computer 1, and the principle of ultraviolet spectra absorption detecting COD of sewage is langbobier law: COD COD in water body has the strongest spectral absorption in ultra-violet (UV) band.
Ultraviolet COD spectral absorption detection device work process is: absorb xenon flash light source 5 as emitter using ultraviolet spectra, photoelectric sensor 7 is as receptor, the light that ultraviolet spectra absorption xenon flash light source 5 sends is irradiated to transparent sensing chamber 10, when there being sewage to pass through transparent sensing chamber 10, the intensity of light will change, light is received by photoelectric sensor 7 after lens 6, produce the electric impulse signal that the size with COD is ratio, by filter amplifier 8, microprocessor 9 sampling processing, delivers to signal in computer 1.
Preferably, the present invention uses correlation type detection mode, and emitter is installed with the mutual correlation of receptor, and the luminous energy making emitter send enters receptor.When there being detection object to enter between emitter and receptor, measured object will shield lights and cause the light quantity entering receptor to reduce, just can detect the content of measured object according to the change of receptor light quantity.The impact that particulate matter is detected by the factors such as the method stability is high, response fast, the color of object, gloss is smaller.
