Embodiment 1

[0044] Such as figure 1 As shown, the terminal disinfection water purification assembly with water quality monitoring function in this embodiment includes a fluid chamber 1, a sealing component 2, an optical detection module and an end-capping module 6. The fluid chamber 1, sealing component 2, optical detection module, The end-capping module 6 is connected in turn, such as figure 2 As shown, the sealing part 2 is provided with a water inlet 201, and the fluid chamber 1 is provided with a water outlet 101; the optical detection module includes an ultraviolet LED module 3, an LED circuit board 303, and a fluorescent detection module 4, and the LED circuit board 303 is a hollow circle ring structure, the ultraviolet LED module 3 is installed on the ring of the LED circuit board 303, and the fluorescent detection module 4 is installed in the hollow part of the LED circuit board 303; it can be seen from this that the ultraviolet LED module 3 and the fluorescent detection module c...

Embodiment 2

[0057] This embodiment is basically the same as Embodiment 1, the difference is:

[0058] The LED waveband in the ultraviolet LED module 3 is the UVB waveband, and the number of the patch type ultraviolet LED301 is 2; The centripetal inclination is 0 degrees.

[0059] The terminal water purification assembly of this example is placed outside the front end of the faucet.

Embodiment 3

[0061] This embodiment is basically the same as Embodiment 1, the difference is:

[0062]The LED band in the ultraviolet LED module 3 is the UVC band, and the number of patch type ultraviolet LEDs 301 is 8; the center wavelength of the band of the patch type ultraviolet LED 301 is 290nm, and the range of the emission angle is 150 degrees. SMD UV LED301 has a centripetal inclination angle of 60 degrees.

[0063] The wavelength range of 380-500nm is selected for the band-pass filter to selectively transmit only humic substance fluorescence.

[0064] The outer wall of the inner casing 103 is plated with silver film.

Description

technical field [0001] The invention relates to water quality on-line monitoring and ultraviolet sterilization technology in the field of terminal water purification, in particular to a terminal water purification component with dual functions of water quality monitoring and sterilization based on a deep ultraviolet LED solid-state light source and a fluorescence signal calibration method thereof. Background technique [0002] Dissolved organic matter (DOM) in natural water mainly includes macromolecular proteins, medium molecular weight humic acid, fulvic acid and other small molecular substances. The existence of DOM seriously affects coagulation, membrane filtration, advanced oxidation and ion The treatment effects of exchange and adsorption processes, and affect the transformation of heavy metals, pharmaceuticals, and micro-pollutants in personal care products in water treatment processes. In addition, DOM is an important precursor for the formation of disinfection by-pro...
