Seawater micro-plastic online monitoring system

Abstract

The invention discloses a seawater micro-plastic online monitoring system. An upper computer controls a laser to emit laser through a light source control panel, the laser acts on a to-be-detected sample to excite a Raman light signal after exciting light emitted by a Raman probe is emitted by a beam splitter, and the excited Raman light signal is reflected by the beam splitter and then collected by the Raman probe; the collected Raman light signals reach the spectrograph through the receiving optical fiber for photoelectric signal conversion, and the upper computer performs data processing on the Raman light signals processed by the spectrograph and then displays the processed Raman light signals on the upper computer; during image acquisition, a high-resolution digital camera in an imaging unit acquires seawater micro-plastic image information after passing through an objective lens and a beam splitter, and the acquired image information is transmitted to an upper computer to be displayed. Direct measurement of seawater micro-plastics can be realized, the detection speed is high, tedious steps are avoided, chemical reagents are not needed, and secondary pollution to seawater quality is avoided. And meanwhile, an imaging unit is added, so that the morphology of seawater plastic can be represented.

Description

technical field [0001] This patent relates to the field of online monitoring of seawater quality and environment, especially to the field of environmental optical monitoring technology, specifically an online monitoring system for microplastics. [0002] technical background [0003] In recent years, with the rapid development of the economy, microplastic pollution in the marine environment has become increasingly serious. Microplastics may even cause physical and chemical fatal damage to birds, fish and other marine life, thus destroying the marine ecological environment. Traditional microplastic detection methods often have cumbersome steps and high costs, which are difficult to meet the requirements of modern environmental monitoring; the existing online monitoring of seawater microplastics lacks a real-time, fast and accurate online monitoring system, which seriously restricts the detection of seawater microplastics. Monitoring and Control. Contents of the invention ...
