Description

technical field [0001] The invention belongs to the field of water quality detection, and in particular relates to a pipeline-type installed full-spectrum water quality detection device and a method thereof. Background technique [0002] With the continuous development of spectroscopic technology, optical-based water quality analysis instruments have developed rapidly. Different chemical substances have different absorption intensities for different wavelengths of light, and most substances have correspondingly determined ultraviolet-visible absorption spectra. Absorption spectrum reflects the characteristics of substances, which is the basis of full-spectrum water quality detection, and then qualitative and quantitative analysis. At present, the optical water quality analysis instruments on the market mostly use single wavelength or dual wavelength for measurement. When the pollutants in the water are complex, the influence of interfering substances cannot be effectively e...
