Description

A kind of sewage treatment Water Test Kits
Technical field
The invention belongs to water analysis technical field, in particular to a kind of sewage treatment Water Test Kits.
Background technique
Water analysis is also known as hydrochemical analyse.I.e. with the content of various chemical components in chemically and physically method measurement water； Theoretical foundation of the ultraviolet spectrophotometry for water quality detection is langbobier law, is indicated with formula A=KCL, wherein K table Show that absorption coefficient, C indicate the concentration of detected solution, L indicates light path；Benzene, toluene, phenols in water sample etc. are used as mainization Aerobic substance is learned, they have very strong spectral absorption in ultra-violet (UV) band；So ultraviolet absorptivity measurement is surveyed with parallel chemistry titration Amount can be applied in the detection of water-quality COD well；And the substance in various solution determines UV Absorption difference The Quantitative Monitoring analysis of material concentration in solution.
Industrial wastewater is after wastewater treatment, before draining into nature, needs to be monitored the water quality of discharge, in order to realize The continuous processing and discharge of sewage need continuously to monitor water quality；In the prior art, ultraviolet point for water analysis Light photometer needs acquisition sample and sample introduction manually, cannot continuously monitor to water quality.
Summary of the invention
The present invention for it is above-mentioned in the prior art the technical issues of, the water of a kind of automatic sampling, continuous monitoring water quality is provided Matter analyzer.
To solve the above problems, technical scheme is as follows:
A kind of sewage treatment Water Test Kits, including be protected from light shell, light source, monochromator, absorption cell, detector and read dress It sets, the detector, which can according to need, is arranged to purple quick photoelectric tube, red-sensitive cell, photomultiplier tube etc.；The reading dress It sets and can be set to be mounted on the digital display being protected from light on shell；The light source, monochromator, absorption cell and detector are arranged and keep away Light enclosure interior, the monochromator, absorption cell and detector are successively set on the output light path of light source, which is characterized in that institute Stating sewage treatment Water Test Kits further includes sample inlet pool, sample cell and sample-out pool；
The sample cell is placed in absorption cell, and upper and lower side has opening, and upper end opening is connected by sample feeding pipe with sample inlet pool, under End opening is connected by sample outlet pipe with sample-out pool, and the center line of sample feeding pipe, sample cell and sample outlet pipe vertical direction is straight in same On line；
Flow straightener is provided in the sample feeding pipe and sample outlet pipe；
A snorkel is connected between the sample inlet pool and sample-out pool；The junction of the snorkel and sample inlet pool and sample-out pool position In pond body top, liquid level above section；The effect of snorkel is that the pressure of sample inlet pool and sample-out pool is maintained to stablize, and guarantees detection liquid Flow into and out sample room to physical efficiency steady and smooth.
When detecting water quality, only the water sample to be measured of flowing need to be passed through sample inlet pool, water sample sample introduction to be measured is controlled by flow straightener Flow and stability, by sample cell, incident light is partially absorbed by monochromator through sample cell water sample to be measured, detector inspection Its light transmittance is surveyed, absorbance is read by read-out device；Water sample to be measured falls naturally under the effect of gravity, and flowing velocity is uneven Even, water flow disorder can make detection signal noise big, it is difficult to it detects, it is straight in same by the center line that vertical direction is arranged Sample feeding pipe, sample cell and sample outlet pipe and the flow straightener being arranged on sample feeding pipe and sample outlet pipe on line, guarantee water sample to be measured uniformly, Absorption cell is steadily flowed through, detection noise is reduced.
As an improvement of the present invention, the sample feeding pipe of the sewage treatment Water Test Kits and sample outlet pipe and it is protected from light shell The setting of body intersection is protected from light circle, avoids intersection light leakage, has an impact to the absorption peak and absorbance of testing result.
As an improvement of the present invention, dress is rinsed in the sample inlet pool top setting of the sewage treatment Water Test Kits It sets, the flusher includes outer tube and syringe, and the outer tube is connected with sample inlet pool, and the syringe is arranged in outer tube In, elastic seal ring is set between syringe and outer tube, and syringe can move up and down in outer tube, when sewage treatment water quality point After analyzer terminates detection, in order to keep the cleaning of sample cell, prolong the service life, the flusher can be used, sample cell is carried out It rinses, syringe moves down, biggish can be rinsed to sample cell using the syringe needle spray pressure of syringe；It is described Syringe and sample cell histogram to center line on same straight line, can be close to sample as long as syringe needle long enough in this way Pond carries out short distance flushing to it, and cleaning effect is more preferable.
As an improvement of the present invention, the sample inlet pool top of the sewage treatment Water Test Kits passes through water inlet Pipe is connected with treatment tank drainpipe, can continuously monitor to the water that will be discharged in this way, avoid pollution environment；It can The position in sample inlet pool close to bottom of pond is arranged in the bottom end of water inlet pipe, after the water sample depth of sample inlet pool accumulation there was not water inlet pipe Start to monitor again, be more advantageous to the stability and uniformity of sample introduction, reduces detection noise.
As an improvement of the present invention, current stabilization liquid is filled in the sample-out pool of sewage treatment Water Test Kits Body, sample outlet pipe lower end are located under the current stabilization liquid levels, and the current stabilization liquid selective is close with prepare liquid ionic strength, viscosity Liquid, can keep in this way water sample flow out sample outlet pipe when stability, reduce detection noise.
Compared with the existing technology, advantages of the present invention is as follows,
Sewage treatment of the invention with Water Test Kits by the way that the sample inlet pool and the sample-out pool that are connected with sample cell is arranged, it can be achieved that The automatic monitor for continuously of sewage treatment outlet water quality, without hand sampling；Sample inlet pool, sample-out pool and flow straightener and current stabilization liquid Setting be conducive to the steady flow of sample, reduce detection noise, the sensitivity of detection be provided；Sewage treatment water analysis Flusher is arranged simultaneously in instrument, can keep the cleaning of sample cell, avoids having an impact subsequent detection, extends making for sample cell Use the service life.
