Description

Technical Field

[0001] The utility model relates to the technical field of environmental detection, and more specifically, particularly to a portable algae sedimentation and concentration device. Background Art

[0002] Algae are important primary producers. Algae in water bodies are not only a source of food for many aquatic animals, but can also perform photosynthesis to fix carbon dioxide and release oxygen. However, too much algae can lead to a series of environmental problems, such as cyanobacterial blooms. Therefore, in the fields of aquatic biology research and water environment protection, quantitative observation of algae in water bodies is required. Traditional quantitative observation of algae in water generally requires putting 1L of water sample into a plastic bottle, then adding 1mL of concentrated Lugo reagent, shaking it well and taking it back to the laboratory, and then settling and concentrating it in a cylindrical separatory funnel for 48 hours.

[0003] After precipitation, the supernatant is siphoned out using a fine glass tube, and the remaining 15mL-50mL is the concentrated algae sample, which is placed in a small square bottle and sealed for storage. When there are many sample collection points and they are far from the laboratory, this method requires a large number of 1L sample bottles, and the 1L water sample after collection needs to be carried and transferred, which increases transportation costs, reduces work efficiency, and brings inconvenience to sampling and sample concentration. The patent with publication number CN116609164A discloses a portable algae sedimentation and concentration device, which uses a bracket to cooperate with the bubble level and telescopic legs on the platform to achieve rapid horizontal positioning of the bracket outdoors. At the same time, using the hook on the platform, it can realize the temporary storage of multiple tanks, and realize the transportation of multiple tanks at one time, reducing transportation costs and improving work efficiency. However, when used in the field, it needs to be left to stand for 48 hours so that the algae settles in the cone of the bottle body. It has a long sedimentation and concentration time, and it takes a lot of time to be used for algae sedimentation and concentration when used in the field. Utility Model Content
