Abstract

The invention discloses a device for monitoring soluble organic matters in a water body through fluorescence spectrometry and a detection method. The device comprises a stock solution supply assembly,a stock solution separation assembly, a sample collection, detection and dilution assembly, a cleaning and purging assembly and a system control assembly. According to the device disclosed by the invention, physical separation of soluble organic matters in a complex water body according to the volume of the soluble organic matters is realized through organic combination of a micro-filtration membrane, an ultra-filtration membrane and a nano-filtration membrane assembly on a monitoring site, and through measurement of fluorescence spectra of separated solutions, fluorescence spectrum characteristic information is extracted and a recognition comparison database is established; and the device effectively reduces and eliminates information loss caused by fluorescence spectrum overlapping in the mixed water body or covering of weak fluorescence signals by strong fluorescence signals, greatly improves possible result misjudgment of direct water body detection in the prior art, and providesricher, more accurate and finer spectrum identification comparison information for online water quality monitoring, early warning and tracing.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and particularly relates to a device and a detection method for monitoring dissolved organic matter in water by fluorescence spectroscopy in the field. Background technique [0002] Using optical means to monitor water quality parameters by spectrometry is a new technology for online monitoring of water quality. Because the monitoring equipment does not need to use chemical reagents, it has the characteristics of rich information, short measurement cycle, fast detection speed, and low maintenance and use costs. user attention. [0003] At present, most of the existing water quality online monitoring, early warning and traceability instruments are designed and developed based on the change of the fluorescence spectrum of the measured water sample. Light. Through the spectral identification of this specific emission wavelength, the composition and content of different organic sub...
