Abstract

The invention discloses a water body plankton concentrating device and concentrating method. The concentrating device comprises a fixed bracket and a concentrating vessel with a closed inner cavity, wherein the concentrating vessel is fixedly arranged on the fixed bracket, a water injection hole is formed in the upper part of the concentrating vessel, a drainage hole is formed in the bottom of the concentrating vessel, and a dewatering outlet is formed in the side part of the concentrating vessel, an elbow pipe bending and protruding upwards is fixedly connected to the position of the dewatering outlet, a water valve is arranged on the elbow pipe, a filter screen for collecting the water body plankton and a supporting net supported under the filter screen are also detachably arranged in the inner cavity of the concentrating vessel, the filter screen and the supporting net are positioned between the drainage hole and the dewatering outlet in the inner cavity of the concentrating vessel, an emptying valve is also arranged under the concentrating vessel, and a valve hole of the emptying valve is located above the filter screen. The water body plankton concentrating device is simple and easy to operate, and the concentrating method adopting the concentrating device is simple and easy, can be used for concentrating and sampling the water body plankton from a number of water samples, and has high efficiency.

Description

[0001] technical field [0002] The invention relates to a concentrating device and a concentrating method for plankton in a water body. [0003] Background technique [0004] In aquatic biology research, it is often necessary to collect a certain volume of water samples and fix and concentrate them to prepare a certain volume of concentrated samples for qualitative and quantitative analysis of plankton. In the traditional concentration method, a precipitator is mainly used, and the sample can be prepared only after repeated precipitation and constant volume. The precipitation time is long and the process is cumbersome. Therefore, there is an urgent need for a simple and fast concentration device and concentration method for plankton concentration in water bodies. Contents of the invention [0005] The purpose of the present invention is to overcome the disadvantages of the prior art, and provide a plankton concentration device with simple structure and convenient operat...
