Analysis on the Characteristics of Dissolved Organic Matter in Receiving River Water in Wastewater Treatment Plant

[摘要] In this paper, Nash's reagent luminosity and other methods were used to quantitatively and qualitatively study the content of ammonia nitrogen and other substances in the tailwater of urban sewage treatment plant, and to analyze the characteristics of organic matter by fluorescence spectrometry, focusing on different sampling points of rivers by three-dimensional fluorescence spectroscopy. The change in dissolved organic matter in the water sample was characterized. The results show that the dissolved organic matter in the upstream of the river channel is the tryptophan in the protein. After the tail water of the sewage treatment plant is discharged, the dissolved organic matter from the tail water discharge outlet to the downstream river channel is protein, sewage treatment. After the tail water is discharged, there is basically no influence on the composition and transformation of dissolved organic matter in the receiving river channel.
