Embodiment 1

[0058] A sewage plant, in order to solve the problem that the water quality monitoring device of the prior art needs to be calibrated regularly and cannot be monitored underwater for a long time, and cannot effectively monitor the proteins and humic substances concerned in the water treatment process, a problem is proposed. An intelligent water quality monitor that combines ultraviolet and fluorescence methods. Figure 1-4 , which includes a detection part, a power supply 14, 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 fluorescence filter 18 and Fluorescence receiving tube 3;

[0059] The constant current source circuit is connected with the deep ultraviolet LED1 circuit, and the deep ultraviolet LED1 is irradiated on one face of the cuvette 9, and a face parallel to the face of the cuvette 9 is provided with an ultraviolet receivi...

Embodiment 2

[0089]In a sewage plant in Jiangsu, the existing water quality monitoring equipment has low accuracy, and the water surface needs to be calibrated regularly, and the overall data collection and processing speed of the equipment is low, and the detection of organic matter content in water quality is inaccurate. In order to improve the cost performance of sewage treatment, An intelligent water quality monitor combining ultraviolet method and fluorescence method is proposed. Its structure, composition and use method are the same as those in Example 1. Among them, a fluorescence filter with a band-pass wavelength range of 460±10nm is used for the monitoring of humic fluorescence. Sheet 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 combining an ultraviolet method and a fluorescence method and a method for using the same. Background technique [0002] Dissolved organic matter in natural water, especially substances such as humic substances and proteins, participates in photochemical reactions, pollutant migration and transformation, microbial activities and carbon cycling and other geobiochemical processes. In the process of drinking water and sewage treatment, dissolved organic matter is the main object to be removed. Especially in the process of drinking water treatment, humic substances and protein substances are important precursors of disinfection by-products in the chlorination disinfection process, which affect the transportation pipeline. growth of bacteria. The composition and properties of dissolved organic matter have an important i...
