Design of a Long-Term and Real-Time In-Situ Monitor for Cyanobacterial Biomass
摘要
Abstract
In recent years,cyanobacterial blooms occurred frequently in kinds of water bodies,which resulted in deg-radation and impairment of water ecological function,as well as serious harm to aquaculture and other water utiliza-tion. The long-term and real-time monitoring of cyanobacterial biomass in water bodies is an essential measure to prevent and harness cyanobacterial blooms. Based on phycocyanin fluorescence from vivo cyanobacteria,the strength of the fluorescence at 645 nm excited by the 620 nm bright light is detected to evaluate the cyanobacterial biomass in water,and finally a rapid and in-situ monitoring instrument for cyanobacterial biomass in water bodies is developed,supplemented by a specially designed self-cleaning device to keep from manual maintenance and calibra-tions for long-term monitoring. To meet the demand of dynamic monitoring of the temporal and spatial variation of cy-anobacterial biomass in vast water areas and expand the practical range,the GPS technology is utilized to obtain the geographical position information of each monitoring site,and the wireless communication technology is employed to realize the remote real-time online data communication among monitoring sites and the monitoring centre. The exper-imental results show that the linear correlation coefficients of the cyanobacterial biomass and the detection values ex-ceed 0.98,and thus the detection values could reflect the variations of the cyanobacterial concentration accurately.关键词
