Spectrum monitoring system for real-time monitoring of sewage

Abstract

The invention relates to a spectrum monitoring system for real-time monitoring of sewage. The spectrum monitoring system comprises a sewage suction buffer device, a detection pipeline, an optical heterodyne spectrum detection device, a laser-induced breakdown spectrum detection device and a computer. The sewage suction buffer device sucks sewage and enables the sewage to stably flow, and then thesewage is conveyed into the detection pipeline. The optical heterodyne spectrum detection device is arranged on the side face of the detection pipeline and used for detecting the optical heterodyne spectrum of sewage in the detection pipeline. The laser-induced breakdown spectrum detection device is arranged at the tail end of the detection pipeline and is used for detecting the laser-induced breakdown spectrum of the sewage. The computer is connected with the optical heterodyne spectrum detection device and the laser-induced breakdown spectrum detection device and is used for spectral data analysis. The spectrum monitoring system is high in detection speed, higher in sensitivity and accuracy and small in pollution in the detection process.

Description

technical field [0001] The invention belongs to the field of sewage monitoring and relates to a spectrum monitoring system for real-time monitoring of sewage. Background technique [0002] In sewage treatment, the concentration of element ions and molecules contained in sewage is an important indicator. The current sewage monitoring mostly adopts the chemical monitoring method at regular intervals, and there are many testing items. The sewage monitoring system used includes turbidity meter, multi-parameter water quality analyzer, infrared oil measuring instrument, BOD measuring instrument, COD measuring instrument, digester, heavy metal Detectors, water pollutant analyzers, water quality testing reagents, heavy metal reagents, etc., each instrument is aimed at different testing items, some for harmful organic substances, some for heavy metal ions, and some for elements such as phosphorus and sulfur. The composition of the system is relatively complex, and due to its complex...

The current sewage monitoring mostly adopts the chemical monitoring method at regular intervals, and there are many testing items. The sewage monitoring system used includes turbidity meter, multi-parameter water quality analyzer, infrared oil measuring instrument, BOD measuring instrument, COD measuring instrument, digester, heavy metal Detectors, water pollutant analyzers, water quality testing reagents, heavy metal reagents, etc., each instrument is aimed at different testing items, some for harmful organic substances, some for heavy metal ions, and some for elements such as phosphorus and sulfur. The composition of the system is relatively complex, and due to its complex composition, the noise in the detection will overwhelm the signal of some elements or substances with less content, resulting in the failure to detect

In addition, the entire detection process is long, time-consuming and labor-intensive
