Device and method for detecting activity of microalgae in ballast water with polarized optical fluidics

Abstract

The invention discloses a device and method for detecting the activity of microalgae in ballast water of a polarized light fluidic sheet. , the image detection module, the image processing module and the database module are connected, and the control module controls the actions of each module. The monochromatic light source provided by the light source module is irradiated on the camera of the image processing module through the detection module and the imaging module according to the predetermined optical path, and at the same time, the control module controls the relative rotation of the polarizer and the analyzer in the detection module to make the camera capture The microalgae cell images in different polarization states are analyzed and processed by the image processing module to obtain the microalgae cell activity results for display and storage. The technical scheme of the invention solves the problems of difficult detection of microalgae cell activity, complex device structure and inconvenient use in the prior art.

Description

technical field [0001] The invention relates to the technical field of detection of microalgae activity in ship ballast water, in particular to a device and method for detection of microalgae activity in ballast water of a polarized light fluidic sheet. Background technique [0002] Ship ballast water is the water and suspended matter added to the ship to control the ship's heel, trim, draft, stability and stress. Ballast water can be sea water or fresh water, and the source can be ports, rivers or open seas, and it is generally carried by special ballast water tanks or empty cargo tanks. Ships must be loaded with ballast water when they are empty. This is done to ensure that the propeller and rudder are immersed in the water to ensure the effectiveness of the operation, control the balance of the ship, and improve the stability of the ship, even when it is loaded or fully loaded. It also needs to be filled with ballast water. When the ship docks at the wharf for loading o...

AI Technical Summary

Problems solved by technology

Microalgae are discharged into the new sea area along with the ship's ballast water. Due to the lack of natural enemies and their own tenacious vitality, these alien organisms will bring catastrophic damage to the ecosystem of the new sea area, and even lead to the extinction of local indigenous species, seriously threatening the ocean. ecosystem security

At present, there is no good scheme and device for analyzing the activity of foreign organisms in ship's ballast water. Therefore, the problem of detecting the activity of microalgae cells in ship's ballast water needs to be solved urgently
