Problems solved by technology

[0003] After industrial wastewater is treated, it is necessary to monitor the quality of the discharged water before it is discharged into the natural world. In order to realize the continuous treatment and discharge of sewage, it is necessary to continuously monitor the water quality; in the prior art, the ultraviolet spectrophotometer used for water quality analysis The meter needs to manually collect samples and inject samples, and cannot continuously monitor water quality

Embodiment 1

[0021] See figure 1 , A sewage treatment water quality analyzer, comprising a light-proof housing 1, a light source 2, a monochromator 3, an absorption cell 4, a detector 5 and a readout device 6. The detector 5 can be set as a purple sensitive Photoelectric tube, red-sensitive photoelectric tube, photomultiplier tube, etc.; the readout device 6 can be set as a digital display mounted on the light-proof housing 1; the light source 2, the monochromator 3, the absorption cell 4 and the detector 5 is installed inside the light-proof housing 1, the monochromator 3, the absorption cell 4, and the detector 5 are sequentially arranged on the output light path of the light source 2, characterized in that the sewage treatment water quality analyzer also includes a sample injection Pool 7, sample pool 8 and sample out pool 9;

[0022] The sample cell 8 is placed in the absorption cell 4, with openings at the upper and lower ends, the upper opening is connected to the sampling cell 7 throu...

Embodiment 2

[0026] See figure 1 , As an improvement of the present invention, the sampling pipe 18 and the sampling pipe 19 of the sewage treatment water quality analyzer and the light-proof shell

[0027] 1 Set an aperture 14 at the intersection to avoid light leakage at the intersection, which will affect the absorption peak and absorbance of the detection result.

[0028] The rest of the structure and advantages are exactly the same as the first embodiment.

Embodiment 3

[0030] See figure 1 As an improvement of the present invention, a flushing device is provided at the top of the sampling pool 7 of the water quality analyzer for sewage treatment. The flushing device includes an outer tube 11 and a syringe 12, and the outer tube 11 is connected to the sampling pool 7 The syringe 12 is set in the outer tube

[0031] In 11, an elastic sealing ring is arranged between the syringe 12 and the outer tube 11. The syringe 12 can move up and down in the outer tube 11. When the sewage treatment water quality analyzer finishes the test, in order to keep the sample pool 8 clean and prolong the service life, The sample pool 8 is rinsed by using the flushing device, the syringe 12 moves downwards, and the needle of the syringe 12 is used to spray a higher pressure to rinse the sample pool 8; the center line of the syringe 12 and the sample pool 8 in a straight direction In the same straight line, as long as the needle is long enough, it can approach the sampl...

Abstract

The invention belongs to the technical field of water quality analysis, and specifically relates to a water quality analyzer for sewage treatment. The water quality analyzer comprises a light-shadingshell, a light source, a monochromator, an absorption cell, a detector, a readout device, a sample injection cell, a sample cell and a sample discharge cell; by setting the sample injection cell and the sample discharge cell communicating with the sample cell, the continuous automatic monitoring of the water quality of a sewage treatment outlet can be realized, and manual injection is not needed;the setting of the sample injection cell, the sample discharge cell, a flow stabilizer and steady flow liquid is beneficial to the stable flow of a sample, the detection noise is reduced, and the detection sensitivity is improved; and the water quality analyzer for the sewage treatment is provided with a flushing device at the same time, so that the cleaning of the sample cell can be kept, the influence on the subsequent detection is avoided, and the service life of the sample cell is prolonged.

Description

Technical field [0001] The invention belongs to the technical field of water quality analysis, and particularly relates to a sewage treatment water quality analyzer. Background technique [0002] Water quality analysis is also called water chemical analysis. That is, chemical and physical methods are used to determine the content of various chemical components in water; the theoretical basis for UV spectrophotometry for water quality detection is Lambert Beer’s law, expressed by the formula A=KCL, where K represents the absorption coefficient and C represents the measured The concentration of the solution, L represents the optical path; benzene, toluene, phenols, etc. in the water sample are the main chemical aerobic substances, and they have strong spectral absorption in the ultraviolet region; therefore, the ultraviolet absorbance measurement and parallel chemical titration measurement are both It can be well applied in the detection of water quality COD; and the substances in...
