Problems solved by technology

Each treatment point can only treat 3,000 cubic meters of algae water rich in cyanobacteria, with an investment of nearly 100 million yuan, high cost and small treatment capacity, and the problem of secondary pollution has not been solved
[0009] Although the formed algae sludge can be anaerobically fermented to produce biogas to generate electricity, but the biogas residue and biogas slurry after power generation need to be treated again, so there are still defe

Example Embodiment

[0052] Example one:

[0053] Participate figure 1 The first embodiment of a cyanobacteria deep well treatment equipment is shown.

[0054] In this embodiment, the cyanobacteria deep well treatment equipment includes a deep well 10 with a water inlet 100 on the top and inserted into the bottom 1 of the water body. The deep well 10 is cylindrical, and its cross-section can be round, oval, square or any other shape. The deep well 10 is inserted into the silt at the bottom of the lake. One or more drainage devices 40 are provided on the side of the deep well 10 higher than the bottom 1 of the water body.

[0055] Meanwhile, in this embodiment, the height of the water inlet 100 in the vertical direction may be flush with or lower than the height of the water body surface 2, and is further preferably lower than the height of the water body surface 2. The water body rich in cyanobacteria in the surface layer of the lake can flow into the deep well 10 from the water inlet 100 and cross th...

Example Embodiment

[0065] Embodiment two:

[0066] Participate figure 1 , Image 6 and Figure 7 The second embodiment of the blue-green algae deep-well treatment equipment is shown.

[0067] Compared with the cyanobacteria deep-well treatment equipment shown in this embodiment, the main difference is that in this embodiment, the cyanobacteria deep-well treatment equipment also includes sleeves on the top of the deep well 10 It is used to adjust the height of the water inlet 100 to the surface 2 of the water body to introduce the adjustable sleeve 30 floating on the surface of the water body.

[0068] There is a certain gap between the inner wall surface 31 of the adjustable sleeve 30 and the outer wall surface 11 of the deep well 10, so that the adjustable sleeve 30 and the deep well 10 can flexibly realize the longitudinal opposite approaching movement or the reverse away movement between the adjustable sleeve 30 and the deep well 10. The change in the height of the water surface 2 caused by the hi...

Example Embodiment

[0072] Embodiment three:

[0073] Participate figure 2 The third embodiment of the cyanobacteria deep well treatment equipment is shown.

[0074] Compared with the blue-green algae deep-well processing equipment shown in any of the above embodiments, the main difference between the blue-green algae deep-well processing equipment shown in this embodiment is that in this embodiment, the top of the deep well 10 is also provided with a An adjustable sleeve 30a floating on the surface 2 of a body of water.

[0075] The adjustable sleeve 30a is composed of a cylinder that is embedded on the inner wall surface of the top of the deep well 10 and can slide longitudinally with the deep well 10 and is integrated with a floating device. The sides of the cylinder are provided with a number of water passing holes 313. The water passing hole 313 is submerged below the surface of the water body. The cylinder can move vertically up and down in the water inlet 100.

[0076] In this embodiment, the c...

Abstract

The invention provides a blue alga deep well treatment device and a blue alga treatment method. The blue alga deep well treatment device comprises a deep well and a water draining device, the top of the deep well is provided with a water inlet and is inserted to the bottom of water, the water draining device is arranged at the side part of the deep well and is higher than the water bottom, the water draining device is connected with one end of a water draining tube, and the other end of the water draining tube extends to the bottom of the deep well. A hydrostatic pressure formed at the bottom of the deep water by the water guided into the deep well is used to break blue algae in order to form blue alga fragments, and a negative pressure formed by the water draining device guides the blue algae to the bottom of the deep wall and discharges the blue algae from the deep well in order to make the blue algae directly preyed by fish, zooplanktons and benthonic animals in the water, so the high-efficiency ecologic treatment of the blue algae is realized, the blooming of the blue algae is effectively prevented, and the water quality is effectively improved, thereby the blooming of the blue algae is fundamentally prevented, the blue alga pretreatment cost is reduced, and stink is prevented.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a cyanobacteria deep well treatment equipment and a cyanobacteria treatment method based on the cyanobacteria deep well treatment equipment. Background technique [0002] Eutrophication of water bodies, global warming, changes in hydraulic conditions and other factors have caused the explosive growth and reproduction of cyanobacteria in most lakes and ponds across the country to form algae blooms, which gather in large numbers with the wind direction. The cyanobacteria gathered in a large area are easily necrotic and corrupt, affecting water quality, threatening drinking water safety, and destroying the water landscape. The stench emitted seriously affects the life and production of coastal residents. Dissolved oxygen destroys the living conditions of benthic organisms and causes water ecological hazards. The control of cyanobacteria blooms is imminent....
