Examining system.
Background technology
Water is Source of life, and water is the base of dream.Although water resource belongs to renewable resource, but be not inexhaustible use
It is inexhaustible.However, recent decades, China is with the system such as sharply increase developed rapidly with population of industrialization, urbanization
Row factor, cause China's water pollution situation startling.According to statistics, in domestic 1200 monitored a plurality of rivers, 850 a plurality of incidents
It is stained significantly, fishes and shrimps disappearance；In state's control emphasis lake, water quality accounts for 39.3% for pollution level, a large amount of natural lakes disappear or
Large area is reduced；Marine pollution also allows of no optimist.
At present, China's water-quality COD, BOD, TOC detection be mainly by artificial collection water sample, using laboratory chemical analysis as
Main Means, because chemical method resolution sample needs the regular hour, and contain the weight such as silver ion, chromium ion in digestion agent
Metal, secondary pollution, detection cycle length, and complex operation are caused frequently, it is necessary to the experimenter of specialty.Laboratory chemical
Analysis method is offline inspection, can not promptly and accurately reflect water pollution situation, lose validity, can not meet to examine water quality
Survey the online, requirement of real-time.Most of water-quality CODs that China uses at present, BOD, TOC detecting instrument, also substantially belong to
In chemical analysis, cycle length, fault rate are high, costly, can not adapt to modernize environment measuring technical requirements.
The content of the invention

Both sides, the ultraviolet-visible light that light source is sent through optical fiber transmit to incidence probe be irradiated to detection water tank in, water sample to it is ultraviolet-
Visible ray produce absorption, the ultraviolet-visible light after absorption be radiated at outgoing probe on, outgoing probe by after absorption it is ultraviolet-can
See that light is transmitted through the fiber to spectrometer, spectrometer converts optical signals to digital spectrum signal and transmitted to signal processor, letter
Number processor carries out wavelet decomposition to receiving spectral signal, selects optimal wavelet function, it is determined that optimal Decomposition order, is utilized
Mallat algorithms decompose to signal；Each layer of high-frequency wavelet coefficient carries out threshold process after decomposition, selects appropriate threshold,
Threshold value quantizing is carried out to wavelet coefficient；Wavelet coefficient after being quantified according to value reconstructs to obtain the spectral signal after noise reduction process, on
Position machine is compared by the spectral signal after noise reduction process with standard spectrum, calculates the data of COB, BOD, TOC in water sample,
And by concentration data storage in memory.
Preferably, when COB, BOD, TOC data exceed setting value in the water sample, host computer sends startup to alarm
Signal.
Preferably, the wavelength for the ultraviolet-visible light that the light source is sent is 195-1000nm.
Compared with prior art, beneficial effects of the present invention：
The present invention realizes the detection of COB, BOD, TOC data in water sample by non-contacting mode, has multiple functional, detection essence
The advantages of degree is high, testing cost is low, non-secondary pollution.
