[0056] In order to make the technical means, creative features, goals and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0057] The specific operation process of the ship ballast water membrane concentration automatic counting method is as follows:
[0058] Taking the detection of ship ballast water samples as an example, 1m of ship ballast water samples were taken on site 3 → Filtration on site to obtain a concentrated water sample of about 100ml → Vacuum filtration of the concentrated water sample in the laboratory → Microscopic imaging of the filter membrane → Stitching images at the workstation → Automatic counting by software → Manual counting by looking at pictures.
[0059] Since the amount of living microorganisms ≥ 50um in ship's ballast water is very small, the concentration in seawater is usually 100 / m 3 , so each sample must be collected not less than 1m 3 ba...
