Description

Phytoplankton subsides concentrated collector fast

Technical Field

The utility model belongs to the technical field of phytoplankton subsides, especially indicate a concentrated collector is subsided fast to phytoplankton.

Background

Phytoplankton is also called phytoplankton, and is a tiny plant which grows in water in a planktonic way and is also an indicator organism for detecting water quality. In recent years, the phenomenon of water environmental pollution happens occasionally, and partial reservoirs and lakes in China are in a water eutrophication state and are accompanied by the phenomenon of algal bloom. Therefore, the monitoring of phytoplankton in water has become an important part of water quality monitoring. The existing detection device mostly adopts a separating funnel and a plastic siphon to remove supernatant, so that the volume of a concentrated sample is difficult to control, the volume of the sample is large before and after concentration, and a scale-free settler is used for sampling, so that the sample cannot be accurately sampled, and the precipitated sample is too much or too little. Meanwhile, in the sampling process, the sample needs to be preserved by using the Rogowski liquid, and the Rogowski liquid has strong corrosivity and can remain in a siphon tube to influence the collected cleaning liquid and further influence the measurement of the next sample; and the siphon pipe of using for a long time can damage and cause the waste liquid to leak, causes the injury to the experimenter, for this reason, we have proposed a phytoplankton subsides concentrated collector fast.
