Description
Technical field
The present invention relates to a kind of water quality monitoring instrument, more particularly to a kind of integrated recombiner.
Background technology
Chemical oxygen consumption (COC) (abbreviation COD) is the overall target of water quality organic contamination, is most important in water quality routine monitoring
One of project.China's national standard (GB 17378.4-2007) regulation is using potassium permanganate as oxidant oxygen in the basic conditions
Change seawater sample, chemical oxygen consumption (COC) is calculated by the consumption of oxidant potassium permanganate.
Standard conditions are complicated, time-consuming, laborious.Therefore, COD analysis methods that are easy, fast and automatically changing and instrument are explored
The effort target of device is always environmental monitoring work person.Since the eighties in last century her Vinh Long history of Japanese scholars first will flowing note
Penetrate analytical technology to be introduced into COD on-line determinations, develop automation COD analytical instrument.Subsequent other scholars have been developed different
Flow injection COD mensurations are studied, and after last century the nineties, various countries have developed various COD online analyzers in succession, its
Middle recombiner plays a key effect as the important component of COD online analyzer in COD measure.
But seawater sample is different from fresh water, because seawater contains substantial amounts of calcium, magnesium ion, hydrogen-oxygen is generated in the basic conditions
Change calcium and magnesium hydroxide white colloidal insoluble matter, and because Flow Injection Analysis process is carried out in the thin pipe of closing, it is this
White colloidal insoluble matter easily blocking pipeline, and COD determines and uses optical detection technique, this white colloidal insoluble matter,
Influence light detection.Common solution is to be dissolved calcium hydroxide and magnesium hydroxide white colloidal insoluble matter with hydrochloric acid, then is gone
Light is detected.So due to adding the hydrochloric acid of certain volume, necessarily increase total volume of reaction solution, so that diluting reaction knot
Really, larger evaluated error is caused.
The sea water COD analyzer designed before National Ocean Technology Center is exactly double current-carrying double injection flow passage structures (see figure
4)。
Main road is alkali road, quantitative using rotation sampling valve, is respectively tried water sample and potassium permanganate with two rotation sampling valves
Sodium Hydroxide Alkaline main road is injected in agent.Bypass (sour road) design be in order to dissolve alkaline sedimentation, but its negative effect can also make it is anti-
Answer solution to dilute, cause sensitivity decrease.Double injection is designed as water sample and reagent difference sample injection, and water sample and reagent are in pipeline
In lean on diffusion contact, water sample and reagent contact are few, and chemically reacting, insufficient (what the top of Fig. 4 represented is water sample and reagent in pipe
Distribution scenario in road).It is possible when this design is exceedingly fast for reaction speed or sample concentration is very high, and COD is surveyed
Surely it is the slower redox reaction of reaction speed, it is not high so as to also result in sensitivity.
Generally existing drawbacks described above during present sea water COD is determined, therefore how to solve drawbacks described above, as now urgently
Technical problem to be solved.
