Method and device for stream guidance and enrichment of blue-green algae in large water area

Abstract

The invention belongs to the technical field of environmental protection, and particularly relates to a method and a device for stream guidance and enrichment of blue-green algae in a large water area. With the adoption of the method and the device for the stream guidance and the enrichment of the blue-green algae in the large water area, a certain area which is in shore, and in which the guiding wind is in the downwind direction in the large water area is selected as a blue-green algae stream guidance and enrichment area; a blue-green algae stream guidance and enrichment device is established by utilizing an arched soft algae blocking enclosure and a stream guiding door of which the two sides are in shore; large-scale blue-green algae from outside is guided and gathered to the two sides of the shore by utilizing the arched soft algae blocking enclosure; and the blue-green algae is guided into the enrichment area by utilizing timely opening and closing of the stream guidance door, or the enriched blue-green algae is prevented from blowing and escaping with wind; wind waves in the enrichment area can be reduced by the blue-green algae stream guidance enrichment device, so that the blue-green algae in the enrichment area can always float onto the water surface, and is conveniently to be absorbed and cleared continuously; and in addition, a blue-green algae stream guiding enrichment trap and an efficient algae absorbing area are constructed at one side close to the bottom shore in the blue-green algae stream guidance and enrichment area by utilizing vantage ground, so that the blue-green algae in the enrichment area is further enriched for second time to the area, and is conveniently efficiently absorbed and cleared.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a method and device for diversion and enrichment of cyanobacteria in large water areas. Background technique [0002] Many large lakes in my country (such as Taihu Lake, Dianchi Lake, etc.) are facing ecological problems such as cyanobacteria blooms caused by water eutrophication. The improvement of water quality in large water areas often requires a relatively long process. How to prevent the occurrence of cyanobacteria blooms before the water quality has been fundamentally improved, and how to quickly and efficiently reduce their biomass after the occurrence, reduce the internal load of algae pollution, and create conditions for further improvement of water quality and the improvement of the lake ecosystem. common concern of the people. In order to solve this problem, people adopt more methods at present to use physical, chemical or biological met...

AI Technical Summary

Problems solved by technology

However, due to the large area of ​​large waters and the large wind and waves, cyanobacteria are often distributed in a wide range, and are easy to float with the wind or mix with bottom water, so that these methods can only play a certain role whether they are used alone or comprehensively. Fundamentally respond to the needs of large water cyanobacteria control and efficient removal
