Description
Technical field
The utility model relates to the water pollution detection range, especially a kind of real-time detection chemical oxygen demand of water body instrument.
Background technology
COD in the water quality (chemical oxygen demand (COD)) is one of monitoring index of water pollution, at present both at home and abroad hand-held, portable Water Test Kits are in detecting water quality during COD (chemical oxygen demand (COD)) pollution factor, all need add reagent, and under 145--165 ℃ of temperature, heat 30? 20 minutes, be cooled to room temperature after clearing up, carry out photometric measurement.Analyzing data just can obtain later at 2 hours.Both expended time in, to analyzing the active demand of data, caused secondary environmental pollution because of adding chemical reagent again in the time of can not adapting to generation environmental protection emergent accident.
The utility model content
The purpose of this utility model provide a kind of simple in structure, detect rapidly, need not add chemical reagent, real-time detection chemical oxygen demand of water body instrument that accuracy of detection is high.
Real-time detection chemical oxygen demand of water body instrument of the present utility model is achieved by following technical proposals.Detect the chemical oxygen demand of water body instrument in real time, comprise ultraviolet source 1, quartz colorimetric utensil 3, ultraviolet source 1 irradiation quartz colorimetric utensil 3, contain sewage to be detected in the quartz colorimetric utensil 3, also comprise selectivity lens 4, spectro-grating 6, reference photoelectric sensor 5, ccd array photoelectric commutator 7, computing machine 9 is connected with ccd array photoelectric commutator 7 with reference photoelectric sensor 5 by telecommunication cable 8, the ultraviolet light that described selectivity lens 4 will be injected in the light source partly projects spectro-grating 6, and natural light is projected reference photoelectric sensor 5 after refraction.As a kind of improvement, can comprise that also the ultraviolet light that ultraviolet source 1 is sent between ultraviolet source 1 and quartz colorimetric utensil 3 is focused into the optical path adjustment device 2 of source of parallel light, this optical path adjustment device 2 is made up of lens that are arranged in order and slit plate.Described ultraviolet source 1 can adopt stroboscopic light source.
Real-time detection chemical oxygen demand of water body instrument of the present utility model compared with prior art has following good effect:
Detection chemical oxygen demand of water body apparatus structure is simple in real time, accuracy of detection is high, need not add the chemistry examination, and environment is not caused secondary pollution, detects rapidly, can tackle the environmental protection emergent accident that happens suddenly to analyzing the active demand of data.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 detects chemical oxygen demand of water body apparatus structure figure in real time.
All can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
Detect the chemical oxygen demand of water body instrument in real time, the ultraviolet light that comprises stroboscopic ultraviolet source 1, ultraviolet source 1 is sent is focused into the optical path adjustment device 2 of source of parallel light, this optical path adjustment device 2 is made up of lens that are arranged in order and slit plate, through adjusted rayed quartz colorimetric utensil 3, contain sewage to be detected in the quartz colorimetric utensil 3, through behind the sewage to be measured, respective change all takes place in the wavelength components of natural light and ultraviolet light.The light that should see through sewage is by selectivity lens 4, and selectivity lens 4 partly project spectro-grating 6 with ultraviolet light, and natural light is projected reference photoelectric sensor 5 after refraction.Spectro-grating 6 separates according to wavelength the ultraviolet light part that receives in the space, generate a series of ultraviolet beams that wavelength is arranged of pressing, the beam split back reflection is to ccd array photoelectric commutator 7, and the ultraviolet conversion of signals that is separated into different wave length that this ccd array photoelectric commutator 7 will receive is to be transferred to computing machine 9 behind the electric signal.5 pairs of sewage to be measured of reference photoelectric sensor carry out turbidity and detect, and are transferred to computing machine 9 after the natural light that receives partly is converted to electric signal, and these turbidity data are revised the ultraviolet light photo signal data that ccd array photoelectric commutator 7 obtains; Computing machine 9 is handled by two groups of electrical signal datas that will receive, and according to the light intensity of each wavelength of revised ultraviolet, comparison chemical oxygen demand of water body model obtains chemical oxygen demand of water body COD value.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
