Water pollution analysis method based on ultraviolet visible spectrum and three-dimensional fluorescence spectrum

Abstract

The invention discloses a water pollution analysis method based on an ultraviolet visible spectrum and a three-dimensional fluorescence spectrum. The specific steps of the operation method are as follows: sampling water quality, namely carrying out multi-point sampling on an analysis water source through sampling equipment, and then preparing a polluted water sample and a purified water sample; collecting a three-dimensional fluorescence spectrum, namely irradiating multiple bottles of collected water samples, polluted water samples and purified water samples through ultraviolet rays to reflect fluorescence signals, and enabling the fluorescence signals to generate the three-dimensional fluorescence spectrum through a diffraction grating; converting a three-dimensional fluorescence spectrum, namely converting the three-dimensional fluorescence spectrum into an electric signal through a CMOS chip so as to obtain three-dimensional fluorescence spectrum data in the form of the electric signal; processing the three-dimensional fluorescence spectrum data, namely preprocessing the three-dimensional fluorescence spectrum data. The method is reasonable in design and accurate in analysis, the three-dimensional fluorescence spectrum data can be corrected, the accuracy of sewage analysis data is well guaranteed, and a certain scientific basis is provided for a water pollution treatment method.

Description

technical field [0001] The invention belongs to the technical field of water pollution analysis methods, in particular to a water pollution analysis method based on ultraviolet visible spectrum and three-dimensional fluorescence spectrum. Background technique [0002] Water pollution is the reduction or loss of the use value of water caused by harmful chemical substances, polluted water, acids, alkalis, oxidants in sewage, and compounds such as copper, cadmium, mercury, arsenic, benzene, dichloroethane, ethylene dichloride, etc. Alcohol and other organic poisons will kill aquatic organisms and affect drinking water sources and scenic spots. When organic matter in sewage is decomposed by microorganisms, it will consume oxygen in water and affect the life of aquatic organisms. After the dissolved oxygen in water is exhausted, organic matter will be anaerobic. Decomposition produces unpleasant gases such as hydrogen sulfide and mercaptans, further deteriorating water quality, s...

Problems solved by technology

[0004] With the development of industry, the components contained in sewage are complex, such as non-corroded fat and other biological macromolecules with uneven particle size distribution, which will produce scattering when irradiated by ultraviolet rays, resulting in inaccurate quantitative detection results, which makes it difficult to ensure the realization of the components in polluted water. Accurate analysis, and a large amount of analysis data, the analysis efficiency of existing devices is low, and cannot meet people's use requirements, so it is necessary to study a water pollution analysis method based on ultraviolet-visible spectroscopy and three-dimensional fluorescence spectroscopy
