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

[0020] see figure 1 , a water quality analyzer, including a light-proof housing 1, a light source 2, a monochromator 3, an absorption pool 4, a detector 5 and a readout device 6, and the detector 5 can be set as a purple-sensitive photocell, Red sensitive photocell, photomultiplier tube etc.; Described readout device 6 can be set to the digital display that is installed on the light-proof housing 1; Described light source 2, monochromator 3, absorption pool 4 and detector 5 are arranged with 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, and it is characterized in that the water quality analyzer also includes a sample pool 7 and a sample pool 8 and sample cell 9;

[0021] Described sample cell 8 is placed in the absorption cell 4, and upper and lower ends all have opening, and upper end opening links to each other with sample pool 7 through sampling tube ...

Embodiment 2

[0025] see figure 1 , as an improvement of the present invention, the intersection of the sample inlet tube 18 and the sample outlet tube 19 of the water quality analyzer and the light-proof housing 1 is provided with a light-proof ring 14 to avoid light leakage at the intersection, and the absorption peak and absorbance of the test results make an impact.

[0026] The rest of the structures and advantages are exactly the same as in Embodiment 1.

Embodiment 3

[0028] 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, and the flushing device includes an outer tube 11 and a syringe 12, and the outer tube 11 communicates with the sampling pool 7, so that The syringe 12 is arranged in the outer tube 11, and 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. After the water quality analyzer finishes testing, in order to keep the sample pool 8 clean and extend the use service life, the flushing device can be used to flush the sample pool 8, the syringe 12 moves downwards, and the needle of the syringe 12 is used to spray the higher pressure to flush the sample pool 8; the syringe 12 is in the same direction as the sample pool 8 The central line of the needle is on the same straight line, so as long as the needle is long enough, it can approach the samp...

Abstract

The invention belongs to the technical field of water-quality analysis and particularly relates to a water-quality analyzer. The water-quality analyzer comprises a light shading shell, a light source, a monochromator, an absorbing tank, a detector, a readout device, a sample injection tank, a sample tank and a sample discharging tank. The water-quality analyzer has the advantages that by arrangement of the sample injection tank and the sample discharging tank communicated with the sample tank, continuous and automatic monitoring for the water quality of a discharging port for sewage treatment and manual sample injection is not needed; the arrangement of the sample injection tank, the sample discharging tank, a flow stabilizer and flow-stabilizing liquid is beneficial to stable flowing of samples, reduction of detection noise and improvement of detection sensitivity; and simultaneously, due to arrangement of a cleaning device, the cleanness of the sample tank can be maintained, the influence on the following detection can be avoided and the service life of the sample tank can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of water quality analysis, in particular to a water quality analyzer. Background technique [0002] Water quality analysis is also called water chemical analysis. That is to use chemical and physical methods to determine the content of various chemical components in water; the theoretical basis for ultraviolet spectrophotometry in water quality detection is Lambert-Beer's law, which is 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 oxygen-demanding substances, and they have strong spectral absorption in the ultraviolet region; therefore, both ultraviolet absorbance measurement and parallel chemical titration measurement It can be well used in the detection of water quality COD; and the substances in various s...
