Water quality monitoring device and detection method

Abstract

The invention discloses a water quality monitoring device and a detecting method. The water quality monitoring device comprises a shell, a front cover plate and a rear cover plate, wherein 6 hollow cavities are arranged between two end faces in the length direction of the shell. The detecting method of the water quality monitoring device comprises 7 steps of single chip microcomputer detection and the like. The water quality monitoring device successfully utilizes a TDLAS technology underwater, achieves continuous monitoring with low cost, multiple monitoring points and continuous linearity, avoids staff duty, is especially suitable for the characteristics of long lasting, continuity and mutability of hydrology and water quality monitoring and possibly has a positive effect on detecting and monitoring existing water quality environment.

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, specifically a water quality monitoring device and a detection method. 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 mea...

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
