Analysis of variation of algae and organic matter in raw water transformation using 3-D fluorescence spectroscopy

  • 摘要: 采用新型分析技术三维荧光谱图方法对深圳东江水源工程水体中藻类进行了荧光分析。实验结果表明,水体中有较丰富的藻类,其中蓝藻、绿藻呈优势藻种,实验期间沿程水体叶绿素a浓度在1.71~16.43μg/L之间,藻密度在72.92万~1 375万个/L之间。三维荧光方法能较好表征水体中生长藻类种类和数量,三维荧光强度F(A.U)与叶绿素a浓度Chla(μg/L)、藻密度N(104个/L)呈较好的线性关系。三维荧光方法能较好的鉴别水体中可溶性有机物腐殖酸和蛋白质,并表征其含量多少。

     

    Abstract: A kind of new technique,3-D fluorescence spectroscopy (TDFS),is used to analyse the phytoplankton of Shenzhen Dongjiang water source project.It is found that there are abundant algaes in the water through all the pipe line.The chlorophyll-a concentration is between 10.71 and 16.43 μ g/L,and the algae biomass vanges from 72.92 to 1 375×104/L.TDFS can basically identify the species and quantity of algaes in water.There is distinct interconversion between fluorescence intension with chlorophyll-a concentration and the algal biomass.Furthermore,different kinds of dissolved organic matters and their concentration can be identified with TDFS method.
