The invention can automatically dilute the high-concentration water sample with high efficiency, can be integrated with a microprocessor in the industrial production, sets time, regularly extracts, and saves the trouble of manual operation.
Description
Technical field
The present invention relates to a kind of waste water detection method, especially relate to a kind of method that is applicable to dynamic flow diluting high-concentration solution to be measured in the technical analysis field.
Background technology
At present, in the technical analysis field, to the analysis of liquid, the analysis like water quality accounts for quite great proportion.And the analysis to the high concentration water sample of water-quality guideline is particularly important in water analysis.But because the limitation of cost and technology; Can't directly measure the high concentration water sample of water-quality guideline at present; To analyze the high concentration water sample of water-quality guideline; At first to the high concentration water sample of water-quality guideline be diluted, make the high concentration water sample be converted into the low concentration water sample, carry out analysis to measure then.And be exactly that to make the volume of the mixed solution that obtains solution at last be the multiple of quantitative high concentration water sample volume through in quantitative high concentration water sample, adding distilled water to the principle of high concentration water sample dilution, up to reach can directly measure till.
Promptly to make the volume of the mixed solution that obtains solution at last be the multiple of quantitative high concentration water sample volume through in quantitative high concentration water sample, adding distilled water in traditional general manually-operated of the dilution process to the high concentration water sample; Through stirring or rocking it is stirred mixed solution then; Leave standstill; The last high concentration water sample of getting again after the quantitative dilution directly measures analysis result, and whole dilution is loaded down with trivial details consuming time, waste reagent.
Utility model patent ZL200920123627.0 has announced a kind of optics quantitative sampling device that is used for quantitative adjustable quantitative volume; Comprise that at least one holds the container of solution to be measured, light source, optical inductor and in container, pump the sampling pump of liquid; Support, last lower lock block.This device is used for liquid is carried out quantitatively, and is not used in the dilution to liquid.
Summary of the invention
The technical matters that the present invention will solve has provided a kind of suitable industrialization use, weak point consuming time, and no reagent waste, dilution is accurate, the dilution process of the high concentration solution to be measured of good reproducibility.
For solving the problems of the technologies described above the cooperation of the present invention, adopt following method dynamic flow diluting high-concentration solution to be measured through the optics proportioning device: at first, the amount of the amount of the highly concentrated solution that setting will be extracted on the optics proportioning device and the dilution that will add; Then,, in the optics proportioning device, extract highly concentrated solution, when highly concentrated solution reaches the amount that a last step sets, close this passage through being arranged on a passage of the hyperchannel piece under the optics proportioning device; Next step through being arranged on another passage of the hyperchannel piece under the optics proportioning device, extracts dilution in the optics proportioning device again, during the amount that above dilution reaches, sets, closes this passage; At last, leave standstill the optics proportioning device after 1-2 minute, the liquid in this optics proportioning device is exactly to accomplish the solution that can directly measure after the dilution.
The present invention also comprises a kind of optics proportioning device that is used for dynamic flow diluting high-concentration solution to be measured; Said optics proportioning device comprises that at least one holds the container of solution to be measured; Optical sensor and in container, pump the sampling pump of liquid; The chamber wall of said container is transparent, and said container is with at least one annulation outward, and the light source that can place optical sensor and the hole of optical inductor are arranged on the said annulation.
Further, described container is a glass material, is shaped as cylindrical.
Further, said annulation is that plastic material is processed, and screw hole is arranged above, and this annulation is fixed on the container through screw.
Owing to adopted above-mentioned method and apparatus, in the process that extracts dilution, high concentration water sample and distilled water carry out mixing of dynamic flow; Mixeding liquid volume is little, so very fast mixed liquor reaches even admixture after leaving standstill a period of time a little, with carrying out response measurement in the mixed solution injecting reactor after the dilution; Whole process weak point consuming time; No reagent waste, dilution is accurate, good reproducibility.Realize robotization high-efficiency agent for dilution high concentration water sample.In commercial production, can combine with microprocessor, setting-up time, timing extraction has saved manually-operated loaded down with trivial details.
