Abstract
The utility model provides a special water pollutant measuring instrument, including a colorimetric cylinder, a lightening barrel and a photometric barrel. The content of pollutants is correspondingly detected through measuring the absorbance of slaking water sample. As the special colorimetric cylinder can be directly applied in the slaking reaction of water sample, the operational process is greatly simplified; as both light-emitting components and photometric components are semi-conductive components, the measuring instrument has the advantages of simple structure, convenient operation, high measuring precision, strong stability and being difficult to have faults. The utility model can be used for measuring and detecting the chemical oxygen demand and ammonia nitrogen in waste water or other water.
Description
Technical field
The utility model relates to a kind of water polluant survey meter, and particularly a kind of method of utilizing the measuring samples absorbance is measured the measuring instrument of contamination index such as contained chemical oxygen demand (COD) and ammonia nitrogen in the waste water.
Background technology
Present measurement to water contamination indexs such as chemical oxygen demand (COD), be earlier water sample to be cleared up, measure its particular chemical constituent concentration by titrimetry then, or by its absorbance under specific wavelength of common photometer measurement, extrapolate chemical oxygen demand (COD) etc. according to chemical concentrations or absorbance then, do not have special-purpose surveying instrument.The defective that adopts titrimetry to measure is to need manually-operated, complicated operating process, speed is slow, personal error is big, the defective that adopts common photometer measurement is that the water sample after needing to clear up is poured in the instrument, operate loaded down with trivial details, instrument and easily corroded by soup, and used instrument itself also exists shortcoming such as failure rate height, precision are low, optical stability difference.
The utility model content
The purpose of this utility model is exactly in order to overcome the defective of above-mentioned prior art, provide a kind of simple in structure, easy to operate, measuring accuracy is high, stability is strong, the special measurement instrument that is difficult for breaking down.
The utility model is achieved in that the water contamination meter comprises color comparison tube, lightening tube and light detecting tube, the color comparison tube bottom places between lightening tube and the light detecting tube, constitute a light path with lightening tube and light detecting tube, (or end) is equipped with light-emitting component in the lightening tube, and (or end) is equipped with photometry element in the light detecting tube.During use, the light that light-emitting component sends penetrates by lightening tube, is absorbed by the water sample in the color comparison tube when passing color comparison tube, remainder enters light detecting tube and is measured by photometry element, strong according to the photometry of photometry element institute, can draw the absorbance of water sample, and draw the concentration of the water sample pollutant of surveying thus.
The beneficial effects of the utility model show as by measuring absorbance measurement water contamination index, do not need to carry out titration, avoided all defect that the manual titration brought, color comparison tube on the measuring instrument can be taken out, can before clearing up, detected water sample directly water sample be injected the color comparison tube of measuring instrument, simplified operating process, avoided because of operating the soup corrosion that inconvenience causes, simultaneously because instrument adopts semiconductor light-emitting elements and photometry element, simplify the structure, improve the light stability and the reliability of instrument, improved precision, reduced failure rate.
