Embodiment 1

[0035] The process is to destroy the pseudovacuoles, group structure and cell structure of the collected cyanobacteria through the pressurization mechanism 4, reduce the reproductive capacity of cyanobacteria, and at the same time facilitate the separation and disposal of algae water. The pressure range is 0.5. Adjust the height of the algae collecting bucket 35 so that it is 1mm below the water surface, and the water will gather to the algae collecting bucket 35 to generate a swirling flow, and at the same time, the negative pressure push flow mechanism 37 will generate negative pressure, thereby realizing the cyanobacteria pseudocavitation, group structure and cell When the structure is destroyed, the sucked air is discharged through the air outlet pipe 38, and the algae water is discharged into the air flotation tank 6 through the algae collection pipe 36; Discharge the separated tail water into the sedimentation tank 8, adopt natural settlement and improved harmless floccul...

Embodiment 2

[0045] The process is to use the automatic cyanobacteria collection mechanism 3 to collect cyanobacteria in the near-shore water body, and destroy the pseudovacuole, group structure and cell structure of the cyanobacteria collected by the cyanobacteria automatic collection mechanism 3 through the pressurization mechanism 4, reduce the reproductive capacity of cyanobacteria, and facilitate Separation and disposal of algae water, the pressure range is 0.5, and the height of the algae collection bucket 35 is adjusted by the expansion and contraction of the hydraulic telescopic cylinder 33 to make it 1mm below the water surface, and the water will gather to the algae collection bucket 35 to generate swirling flow, and at the same time The pressure pushing flow mechanism 37 generates negative pressure, thereby realizing the destruction of cyanobacteria pseudocavitation, group structure and cell structure, the air sucked is discharged through the air outlet pipe 38, and the algae wate...

Abstract

The invention discloses a comprehensive treatment device and method for blue-green algae in an offshore water body, and relates to the technical field of blue-green alga treatment devices and methods.The invention aims at solving the problems that the existing treatment method and device both have the defects of treating symptoms but not root causes and cannot effectively inhibit blue-green algaein a natural water body in the early stage. A salvage ship and an automatic blue-green alga collecting mechanism are arranged on the river; the salvage ship is positioned on one side of the blue-green alga automatic collecting mechanism; a pressurizing mechanism is arranged on one side of the river; the pressurizing mechanism comprises an alga removal trap pool and an alga removal trap; the algaremoval trap is located in the alga removal trap pool; an air floatation tank is arranged on one side of the pressurizing mechanism; a centrifugal dehydration mechanism is arranged on one side of theair floatation tank; a sedimentation tank and a purification wetland are arranged on one side of the pressurizing mechanism, one side of the air floatation tank and one side of the centrifugal dehydration mechanism; and the sedimentation tank is located on one side of the purification wetland.

Description

technical field [0001] The invention relates to the technical field of a cyanobacteria treatment device and a treatment method thereof, in particular to a comprehensive treatment device for nearshore water cyanobacteria and a treatment method thereof. Background technique [0002] At present, with the continuous development of social economy, lake eutrophication and cyanobacteria bloom have become a major global environmental problem. Especially in the context of global warming, algal blooms often occur in eutrophic lakes, resulting in a decrease in water transparency and dissolved oxygen, often accompanied by the production of toxins and odorous substances, resulting in deterioration of water quality and damage to aquatic ecosystems. Cyanobacteria outbreaks have endangered human drinking water, and the control and governance of cyanobacteria blooms have become more and more severe. At present, the existing technology is difficult to effectively suppress the blue-green alga...
