Embodiment Construction

[0023] The technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] The invention provides a portable plankton concentration method and device. The device has the following characteristics: firstly, the water sample is manually concentrated, reducing the amount of water sample transportation and sampling workload; secondly, the filter membrane can be manually cleaned without changing the membrane, It can be reused; thirdly, the filtrate collection chamber and the raw water sample storage chamber are connected by threads, which can realize manual memb...

Abstract

The invention discloses a portable plankton concentration device which comprises a sample feeding system, a manual separation system and a filtrate collecting system, the manual separation system comprises a filter membrane support leg, a filter membrane support net, a filter membrane, a raw water storage cavity, a piston push-pull rod and a filtrate collecting cavity; the filter membrane supporting leg is arranged at the open end in the filtrate collecting cavity, the filter membrane support net is laid on the filter membrane support leg, the filter membrane is placed on the filter membrane support net, the other end of the filtrate collecting cavity is provided with a filtrate outlet, the piston push-pull rod is arranged in the raw water storage cavity, a raw water inlet is formed in thebottom of the raw water storage cavity, the filtrate collecting cavity is in matched connection with the raw water storage cavity through threads, the sample feeding system is communicated with the manual separation system through the raw water inlet, and the filtrate collecting system is communicated with the manual separation system through the filtrate outlet. The portable plankton concentration device is simple in structure, convenient to use and capable of effectively reducing the labor intensity and improving the working efficiency.

Description

technical field [0001] The invention belongs to the technical field of water body ecological research, and in particular relates to a portable plankton concentration device. Background technique [0002] Microalgae are widely distributed in oceans, freshwater lakes and other waters. As the most basic link in the food chain of aquatic organisms, they are important participants in the material cycle and energy flow of aquatic ecosystems. Microalgae are often used for global climate change, eutrophication of lake water, marine disasters (degradation of marine ecosystem structure, damage to functional areas, red tide, etc.) The indicator organisms of major ecological and environmental issues such as spp. play an important role in environmental monitoring. Sampling detection is one of the main methods of environmental monitoring. Sampling detection is to intuitively reflect the structural and functional characteristics of the water ecosystem by counting and identifying the micr...
