A ship-mounted multifunctional double-probe algae fluorescence parameter online detection device

Abstract

The invention provides a ship-borne multifunctional dual-probe online detection device for algae fluorescence parameters. The device comprises a light-proof seal box and a water sample pool which is equipped with a water pumping and draining device and arranged in the light-proof seal box, wherein an LED excitation light source module and a dual-probe fluorescence detection module are arranged onthe side wall of the water sample pool; the LED excitation light source module comprises a multi-wavelength LED array, an excitation light detection probe and a light source control circuit module; the dual-probe fluorescence detection module comprises a No.1 probe assembly, a No.2 probe assembly and a signal analysis and processing circuit module; the No.1 probe assembly receives fluorescence with a characteristic wavelength of 675 nm, and the No.2 probe assembly receives fluorescence with a characteristic wavelength of 780 nm. By means of the device, online rapid identification of dominant algae species in unknown water areas, real-time classification measurement of algae concentration and activity detection of algae photosynthesis can be realized, and online identification speed and accuracy of the dominant algae species in water are greatly increased.

Description

technical field [0001] The invention belongs to the technical field of chlorophyll fluorescence detection, in particular to a ship-mounted multi-functional double-probe algae fluorescence parameter online detection device. Background technique [0002] At present, water quality pollution in oceans, lakes, rivers, reservoirs and other waters around the world is becoming more and more serious. Water pollution caused by eutrophication and algae blooms still lack effective treatment methods at this stage. Early warning and prevention of algae blooms is the key to reducing The main measures for the harm of small algal blooms. [0003] The photosynthetic activity of algae and the concentration of algae in the water body are important factors affecting algal blooms, and due to the differences in algal blooms in unknown complex waters, it is necessary to identify different dominant algae online and classify the concentration of algae Measurement. Traditional detection methods gene...
