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...
