Description

technical field [0001] The invention relates to water quality ammonia nitrogen content detection technology in the field of industrial technology, in particular to an ammonia nitrogen image detection device. Background technique [0002] With the development of society and the prosperity of economy, computer technology has been more and more widely used. One of the key indicators for evaluating water pollution status is to detect the ammonia nitrogen content of water quality. Nitrogen is one of the main nutrients for water eutrophication, and the ammonia nitrogen content reflects the degree of water eutrophication. Commonly used automatic online detection technologies for ammonia nitrogen are sensor detection method based on electrochemical effect and spectrophotometric method based on Nessler reaction. The sensor detection method is based on electrochemical reaction. The disadvantage is that the pollutants in the water sample will adhere to the surface of the sensor, causi...

AI Technical Summary

Problems solved by technology

The sensor detection method is based on electrochemical reaction. The disadvantage is that the pollutants in the water sample will adhere to the surface of the sensor, causing the pollution of the sensor. After each detection, the sensor must be cleaned, which is not suitable for long-term online automatic detection.

Nessler's spectrophotometry is based on Nessler's reaction. Nessler's reagent reacts with ammonia nitrogen in the water sample to generate a brown-red compound, which can be used to calculate the content of ammonia nitrogen by detecting its absorbance. The automatic ammonia nitrogen detection device has complex structure, high cost and high failure rate
