Discrete three-dimensional fluorescence/visible light absorption spectrum detection device for judging water quality pollution

Abstract

The invention discloses a discrete three-dimensional fluorescence / visible light absorption spectrum detection device for discriminating water quality pollution, which integrates a water path, a circuit and a light path, adopts a small spectrometer and a prism light splitting module, and is low in cost and convenient to carry and maintain; a discrete three-dimensional fluorescence spectrum and an absorption spectrum can be obtained at the same time in one-time on-site detection, and a characteristic peak is enhanced by utilizing the relevance of light absorption and fluorescence mechanisms. After circulating sampling is set, uninterrupted in-situ continuous measurement can be achieved, obtained spectral data cover water quality abnormal information and pollution type information at different times, and the data obtained through the device can be used for rapidly judging whether pollution exists or not and the pollution type. Through a side cloud cooperation mode, detected bottom layer data does not need to be uploaded to a cloud end for analysis, computing resources can be shared by a plurality of detection devices, the network flow of water quality analysis is saved, and the processing speed and the operation efficiency are improved.

Description

technical field [0001] The invention belongs to the field of fluorescence / visible light absorption spectrum detection, in particular to a discrete three-dimensional fluorescence / visible light absorption spectrum detection device for judging water quality pollution. Background technique [0002] The core content of water quality monitoring is to use online or offline technical means to monitor the water body condition for a long time, store relevant historical data of water quality, analyze and study the change law of water quality, and provide relevant departments with corresponding scientific knowledge when responding to water quality emergency disasters and developing and utilizing water resources. decision basis etc. There are two methods of data acquisition for water quality monitoring: offline means and online means, including environmental quality monitoring and pollution source supervision and monitoring types.

AI Technical Summary

Problems solved by technology

[0004] 1) The means of obtaining water quality information are mainly fixed automatic monitoring stations and laboratory analysis. The detection period is long and the detection methods are complicated. It can only control the overall macroscopic indicators of river water quality, and the monitoring of dynamic water quality conditions is insufficient.

[0005] 2) The level of intelligence is not high, focusing on data monitoring and ignoring data analysis. Most systems only perform quantitative detection of water quality parameters, and issue alarms based on exceeding standards, failing to fully tap the relative changes and hidden information in big data

[0006] 3) A small number of systems with timely early warning and alarm functions can only detect abnormalities, but cannot identify and judge what kind of abnormality it is. Water samples still need to be taken for laboratory analysis, which delays the timing of emergency handling
