Water quality monitoring device

Abstract

The invention discloses a water quality monitoring device. The water quality monitoring device comprises a casing, a front cover plate and a rear cover plate, wherein 6 hollow cavities are formed between two end surfaces in the length direction of the casing. A TDLAS (tunable diode laser absorption spectroscopy) technology is successfully applied to the underwater part, low-cost continuous linearmonitoring of multiple monitoring points is realized, and the water quality monitoring device is unattended, is particularly suitable for meeting the requirements of long term property, continuity andsudden change performance of hydrologic and water-quality monitoring and has positive effect on existing water quality environment detection and monitoring probably.

Description

technical field [0001] The invention belongs to the technical field of environmental protection monitoring, in particular to a continuous laser detection technology based on TDLAS technology, in particular to a water quality monitoring device. Background technique [0002] In the existing water quality monitoring, water samples are generally salvaged in containers and brought to the laboratory for testing, which has the problems of poor timeliness and poor data reliability: [0003] First of all, in practice, the density and type of impurities in different water layers are different, and the process of salvaging the water at the sampling point has the risk of sample contamination and dilution; [0004] Secondly, under the influence of oxygen, sunlight and other factors, the salvaged water samples will volatilize, deteriorate, disperse and other problems; [0005] Thirdly, sampling from sample points also has the problem of small sample size, errors in measurement and statis...

AI Technical Summary

Problems solved by technology

[0002] In the existing water quality monitoring, water samples are generally salvaged in containers and brought to the laboratory for testing, which has the problems of poor timeliness and poor data reliability:

[0003] First of all, in practice, the density and type of impurities in different water layers are different, and the process of salvaging the water at the sampling point has the risk of sample contamination and dilution;

[0004] Secondly, under the influence of oxygen, sunlight and other factors, the salvaged water samples will volatilize, deteriorate, disperse and other problems;

[0005] Thirdly, sampling from sample points also has the problem of small sample size, errors in measurement and statistics, and the lack of inductive analysis formed by accumulation, that is, the shortcomings of point-to-point overview;

[0006] Finally, existing water quality monitoring is a discrete, intermittent detection method

Although there are vehicles or ships to load the equipment, it is costly and consumes a lot of manpower and material resources, so it is not suitable for continuous detection
