Description

Collection and storage device for periphyton

Technical Field

The utility model belongs to the technical field of water ecological remediation, concretely relates to collection storage device of periphyton.

Background

Periphyton is a biological community that grows attached to a substrate, including algae, bacteria, fungi, animals, organic or inorganic debris, etc., and the substrate on which it grows may be organic or inorganic, living or non-living. In the prior art, the collection process of periphyton samples mainly refers to the form of algae contained in the periphyton samples, because the algae are the most important components in various components of periphyton. Therefore, periphyton is collected by phytoplankton collection methods. The attached periphyton is generally directly transferred to the sampling container by using a tool such as tweezers, a brush or a scraper. For periphyton existing in the form of a mass (spirogyra) or an aggregation state (cladophora), the periphyton can be directly fished by a tool such as a filter screen.

The existing sampling method mainly aims at the field of biological investigation research, and can meet the requirement of collecting most periphyton, but has the following problems:
