Abstract

The invention discloses an online digestion and luminosity detection device for water quality. The online digestion and luminosity detection device comprises a condensation and digestion integrated device, a heating system and a detection system, wherein the upper part of the condensation and digestion integrated device has an integrated design with a spiral condensation tube and a digestion cup; a three-way two-position electromagnetic valve is connected with the part below a digestion device; a luminosity detection device is vertically arranged in a black aluminum shell, and comprises a colorimetric pot, a light source, a light guide bar and a photoelectric conversion device; the colorimetric pot has an integrated sintered design, and is arranged vertically; and an overflow opening is formed in the side of the colorimetric pot. The online digestion and luminosity detection device for the water quality has a simple structure and a rational design, is low in cost and high in measurement precision, and can be applied to online water quality detectors based on a spectrophotometry.

Description

technical field [0001] The invention relates to environmental water body monitoring equipment, in particular to a device for digestion and photometric detection of water body pollutants. Background technique [0002] Industrial wastewater and domestic sewage are discharged into rivers, lakes and reservoirs, and the pollution of water bodies in the environment is more serious. On-line monitoring can continuously measure and evaluate water quality when needed. The development of new on-line monitoring instruments is very important. difficult. Water quality analysis is mainly based on the basic principles of analytical chemistry to quantitatively analyze the components to be measured in water. In water quality analysis, absorbance photometry is generally used to measure water quality components. The basic principle and practical application of absorbance photometry is an analytical method based on the selective absorption of light by substances. The most widely used instrumen...
