A cyanobacteria intercepting and collecting device

Abstract

The invention discloses a blue-green algae interception and collection device. The blue-green algae interception and collection device is characterized by comprising a first-stage interception device, a second-stage collection device, a blue-green algae collection pool, flotation equipment and dehydration equipment. The first-stage interception device comprises a plurality of vertical pillars arranged side by side, and the vertical pillars are provided with an interception net. The second-stage collection device comprises a floating device and algae suction pumps, wherein the floating device is composed of a plurality of V-shaped foaming pillars wrapped with canvas, and part of the canvas droops in lake water under the action of gravity; the algae suction pumps are arranged on the sides, facing the blue-green algae flowing direction, of the V-shaped tip ends of the foaming pillars; outlets of the algae suction pumps are connected to an inlet of the blue-green algae collection pool; an outlet of the blue-green algae collection pool is sequentially connected with the flotation equipment and the dehydration equipment. The blue-green algae interception and collection device can relieve the labor intensity for refloating blue-green algae, and improve work efficiency.

Description

technical field [0001] The invention relates to a whole-line collection and centralized treatment system of cyanobacteria, which belongs to the field of preventing and controlling cyanobacteria blooms. Background technique [0002] Due to the eutrophication of water bodies, cyanobacteria bloom disasters frequently broke out in major lakes across the country, which has seriously affected the ecological environment of water bodies. The technologies for removing blue-green algae include physical salvage, chemical algicide algae removal, and biological treatment. Among them, the cyanobacteria salvage method is the most direct and effective method to control the total amount of cyanobacteria. The current salvage method is to set up centralized salvage points along the lake shore and implement fixed-point salvage, mainly using mobile algae suction boats, fixed platforms on the water or fixed-point algae suction on land. Pump suction, and using local terrain to drag the blue-green...

Among them, the cyanobacteria salvage method is the most direct and effective method to control the total amount of cyanobacteria. The current salvage method is to set up a centralized salvage point along the lakeshore and implement fixed-point salvage, mainly using a mobile algae suction boat, a fixed platform on the water or a fixed point on land. Pump suction, and use the local terrain to drag the blue-green algae to the port by artificial trawling and pumping. The above salvage methods have limitations, and the blue-green algae along the line cannot be completely intercepted and collected, and blue-green algae will still flow into the river.

In order to prevent the collection pump from only inhaling the lake water but not the surface cyanobacteria, it is necessary to manually push the cyanobacteria to the suction pump with a scoop net. In high temperature weather, the work efficiency is low and the labor intensity is high. Due to the accumulation of cyanobacteria on the surface of the lake, although a lot of manpower has been spent to prevent the suction pump from only pumping the lake water but not the cyanobacteria, the concentration of cyanobacteria in the pumped algae water is still low, and the energy consumption capacity of the treatment equipment needs to be increased

To sum up, there is currently no comprehensive and efficient collection system to effectively increase the processing capacity of cyanobacteria and solve the bottleneck problem that restricts the accelerated processing of cyanobacteria.
