In situ fluorescence detection device for algae concentration

Abstract

The invention discloses an in situ fluorescence detection device for algae concentration. The invention researches and develops an in situ fluorescence detection technology and device by using multiband LED excitation source and an avalanche diode as a detector. The device solves the problem of the influences of optical measuring window pollution, natural light and turbidity on the fluorescence measurement results, and can meet the requirements for in situ rapid monitoring of concentration of algae in water under field natural illumination conditions. The device can be used in rapid survey of concentration of algae in water in the field, also can be installed on a buoy or an automatic monitoring station for long-term continuous monitoring on algae concentration of fixed monitoring points and has good market prospects.

Description

technical field [0001] The invention relates to the field of algae concentration detection devices, in particular to an in-situ fluorescence detection device for algae concentration. Background technique [0002] With the rapid development of the economy, the ecological environment of many lakes has been seriously damaged, and the problem of eutrophication of lakes has become increasingly serious. The eutrophication of the water body leads to the massive proliferation of algae in the water body. Excessive algae deplete the dissolved oxygen in the water body, causing a large number of aquatic organisms to die, and the water body becomes black and smelly. Especially since the 1970s, the frequency of water blooms in inland lakes and reservoirs in my country has been increasing at a rate of three times every ten years, and the area and duration of a single water bloom have continued to expand, and the degree of damage caused has also increased year by year. . According to the e...
