AI Technical Summary

Technical Problem

Existing spectroscopic water quality testing instruments are mostly single-parameter detectors. These instruments are complex, bulky, and costly, making it difficult to achieve multi-parameter online detection. Furthermore, direct spectroscopic detection is susceptible to interference from different water bodies, resulting in unstable detection. They cannot meet the requirements for three-dimensional, portable, and low-power consumption of cyanobacterial biomass in lakes.

Method used

By employing ultraviolet-visible spectroscopy, combined with a miniaturized fluorescence detection system, dynamic positioning technology, vacuum sealing technology, and real-time data transmission, an algorithm for inverting spectral parameters of the three-dimensional distribution of cyanobacteria in eutrophic shallow lakes was constructed. A three-dimensional lake cyanobacterial biomass spectral detection system was designed, including a host and a probe, which are connected by optical fiber to achieve multi-parameter detection and signal processing.

Benefits of technology

It achieves multi-parameter spectral detection, and the equipment is miniaturized, portable, and low-power. It can perform in-situ, online, and high-precision three-dimensional monitoring of cyanobacterial biomass in lakes. It has a large detection depth, long continuous working time, and accurate positioning, making it suitable for detecting the thickness of cyanobacterial blooms in lakes.
