A kind of underwater biofilm collection system and collection method

Abstract

The invention relates to an underwater biomembrane acquisition system and acquisition method. The underwater biomembrane acquisition system comprises a submerged positioning device, an adhering device and an acquiring and collecting device, wherein the submerged positioning device comprises a hanging steel rope and counterweight blocks; the adhering device is vertically hung on the lower end of the hanging steel rope; the counterweight blocks are hung below the adhering device and endows the whole system with fixing and addressing functions; the main part of the adhering device is a shell with double cavities, a stabilization cavity provides power support for adsorption onto the surface of an object, and a collection cavity is an acquisition place for the biomembrane; and the acquiring and collecting device is a power unit with a scraping brush, and the lower cavity and external environment through hole of the acquiring and collecting device have draining and biomembrane collection functions. Compared with the prior art, the invention has the following beneficial effects: the underwater biomembrane acquisition system is applicable to acquisition of surface biomembranes from underwater parts in reservoirs, dams, bridge piers and the like, is compact in structure, simple to operate, easy in expanded application and excellent in acquisition effect and can excellently accomplish acquisition of biomembranes at underwater deep positions.

Description

technical field [0001] The invention belongs to the field of environmental science, and relates to an underwater biofilm collection system and a collection method. Background technique [0002] In recent years, with the deepening of microbial research in various fields, the exploration of the living state, community structure and succession law of microorganisms has become the most effective and direct means to detect and evaluate the health status of aquatic ecosystems and related research fields. Compared with physical and chemical detection methods, microbial detection can more sensitively and accurately express the influence of different influencing factors, different pollutants and other substances. Therefore, microbial detection methods have become an important research and analysis method in ecological evaluation and related research fields. At the same time, microorganisms often exist in the form of biofilm in the aquatic environment and grow and develop attached to...

Problems solved by technology

[0005] (1) Most of them still use manual collection, with the help of some submersible equipment, to collect samples such as biofilms from shallower parts below the water surface, and the efficiency is low;

[0006] (2) Reservoirs or dams and other buildings with large vertical diving depth and perennial water storage work cannot dive underwater and are difficult to collect
