Embodiment 1

[0058] In a sewage plant, in order to solve the problem that the existing water quality monitoring devices need to be calibrated regularly and cannot be placed underwater for a long time, and cannot effectively monitor the proteins and humus substances that are concerned in the water treatment process, a proposal was made. An intelligent water quality monitor combining ultraviolet and fluorescence methods, combined with Figure 1-4 , it includes a detection part, a power supply 14, and also includes an optical path part and a calibration part, wherein the optical path part includes a constant current source circuit, a deep ultraviolet LED1, a cuvette 9, an ultraviolet receiving tube 2, a fluorescent filter 18 and Fluorescence receiving tube 3;

[0059] The constant current source circuit is connected to the deep ultraviolet LED1 circuit, and the deep ultraviolet LED1 is irradiated on one surface of the cuvette 9, and a ultraviolet receiving tube 2 is provided on a surface para...

Embodiment 2

[0089]In a sewage plant in Jiangsu, the existing water quality monitoring equipment has low accuracy and needs to take out the water surface for calibration regularly, and the overall data collection and processing speed of the equipment is low, and the detection of organic matter content in the water quality is inaccurate. In order to improve the cost performance of sewage treatment, A kind of intelligent water quality monitoring instrument combining ultraviolet method and fluorescence method is proposed. Its structural composition and usage method are the same as those in Example 1, wherein the fluorescent filter with a bandpass wavelength range of 460 ± 10nm is used for the monitoring of humic substance fluorescence. slice 18.

Description

technical field [0001] The invention relates to the fields of environmental monitoring and water treatment, in particular to an intelligent water quality monitor combined with an ultraviolet method and a fluorescence method and a usage method thereof. Background technique [0002] Dissolved organic matter in natural water bodies, especially humic substances and proteins, participates in geobiochemical processes such as photochemical reactions, pollutant migration and transformation, microbial activities, and carbon cycle. In the process of drinking water and sewage treatment, dissolved organic matter is the main object of removal, especially in the process of drinking water treatment, humus and protein substances are important precursors of disinfection by-products in the chlorination disinfection process, affecting the transmission pipeline growth of bacteria. The composition and properties of dissolved organic matter have an important impact on the treatment effects of ac...
