[0003] In the prior art, deep ultraviolet LEDs are usually used to monitor water quality, and the ultraviolet absorption value of the characteristic wavelength is used to predict the chemical oxygen demand (Chemical Oxygen Demand) water quality index or certain pollutants, or the fluorescence method is used to measure the water quality. The detection method is relatively simple, and only part of the water quality parameters in the water body to be tested can be detected.
When it is necessary to monitor various water quality parameters in the water body to be tested, it is often necessary to replace different equipment, and the detection process is more complicated

The invention relates to a water quality monitoring system based on spectral characteristics. The water quality monitoring system based on spectral characteristics utilizes a light source to emit exciting light, the exciting light is separated into exciting light with a single wavelength by a first monochromator, and monochromatic light which is not absorbed by a to-be-detected water body penetrates through the to-be-detected water body and then passes through an ultraviolet detector to obtain an ultraviolet visible light signal; and monochromatic light absorbed by a to-be-detected water body is subjected to electron transition to emit fluorescence, the fluorescence is separated into single-wavelength fluorescence through the second monochromator, a fluorescence signal of the monochromatic fluorescence is detected through the fluorescence detector, and the processor processes the wavelength of the monochromatic light, the wavelength of the monochromatic fluorescence, an ultraviolet visible light signal and the fluorescence signal, so as to obtain a water quality parameter prediction result. Equipment is integrated in one box body device, the device is light and convenient to carry, and the processor performs fusion analysis by utilizing ultraviolet fluorescence data, so that the detection precision of the system is improved.
Description
technical field [0001] The invention relates to the field of water quality monitoring, in particular to a water quality monitoring system based on spectral features. Background technique [0002] With the rapid development of my country's economy and the acceleration of urbanization, a large amount of industrial wastewater, domestic sewage and other wastes have entered rivers, lakes, seas and other water bodies, which will lead to water pollution and deterioration of water quality. Therefore, in the water treatment process It is necessary to monitor and warn the water quality of water bodies. [0003] In the prior art, deep ultraviolet LEDs are usually used to monitor water quality, and the ultraviolet absorption value of the characteristic wavelength is used to predict the chemical oxygen demand (Chemical Oxygen Demand) water quality index or certain pollutants, or the fluorescence method is used to measure the water quality. The detection method is relatively simple, and o...
