Technical Field

The invention relates to the technical field of water resource, water environment, water quality monitoring and the like, in particular to a multi-parameter water quality online monitoring device based on a deep ultraviolet photoelectric detector and a using method thereof.

Background

Water is the basis on which human beings rely for survival and is an essential resource in production and life. With the rapid development of economy and society, the water using mode of the crude technical scheme can not adapt to the increasing water demand, and the phenomena of pesticide and fertilizer overload, sewage stealing, disorderly discharging and the like aggravate the water pollution and seriously harm the water quality health and the water using safety. Water quality monitoring is a powerful means for managing and controlling water pollution conditions, and is the key for mastering the current situation and development trend of water quality. However, the severe current situation of water environment puts higher and higher requirements on surface water quality monitoring, so that the surface water monitoring technology gradually becomes an important component and research topic in water environment protection work in China.

Compared with developed countries, the surface water monitoring work in China starts late, and the surface water monitoring is only 30 years from the beginning to the present in China. The traditional water quality detection method generally adopts an independent water quality detection device or utilizes a sensor to collect water quality data and process, display and control the water quality data, and the data monitored by each monitoring point is difficult to comprehensively summarize and analyze; or by collecting water samples, the corresponding index results are measured in a laboratory by using a specific physical and chemical detection method and a specific detection instrument. When surface water is monitored, a physical and chemical monitoring method is most commonly used, and the application of a remote sensing monitoring technology, an automatic water quality monitoring technology, a biological monitoring technology and the like is still in a research stage and is not mature enough.

The traditional water quality monitoring station has loose layout, small coverage range and single monitoring equipment, and limits the acquisition of all-dimensional water quality data and the deep understanding of the water environment condition of a monitoring section. The ultraviolet water quality detection method is a pure physical optical measurement method, does not need chemical reagents, does not have secondary pollution, has high photoelectric detection speed, can carry out real-time online monitoring, can reflect the dynamic condition of water quality parameters in time, quickly detects sudden pollution accidents, and provides a powerful basis for designing corresponding prevention mechanism countermeasures in a microcomputer.

Ultraviolet-visible molecular absorption spectroscopy is a method for analyzing the composition, structure and concentration of a substance according to the absorption spectrum of the substance, and the basic principle of the method is the lambert-beer absorption law, namely, the concentration of the substance is proportional to the absorbance under a certain absorption optical path:

in the formula: a is absorbance; i is₀Is the intensity of the incident light; i is the transmitted light intensity; k is molar absorptivity and has a unit of L (mol. cm)^-1(ii) a b is the liquid layer thickness (absorption path length) in cm; c is the concentration of the light absorbing species in mol/L.

The ultraviolet-visible spectrum analysis method can directly or indirectly measure the content of most of metal ions, non-metal ions and organic pollutants in water, has the advantages of sensitivity, rapidness, accuracy, simplicity and the like, can realize the detection of various water quality parameters, has obvious technical advantages in the online monitoring of drinking water, surface water, industrial wastewater and other water bodies, and is a modern water quality monitoring technology which is competitively researched and developed by domestic and foreign scientific research institutions and main analytical instrument manufacturers.
