Blue alga deep well treatment device and blue alga treatment method

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....

AI Technical Summary

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 defects of large environmental pollution and high treatment costs

According to calculations, the cost of processing 1 ton of algae mud is more than 200 yuan, and the discharge basically cannot meet the environmental protection standards, there is a serious stench, and the people complain a lot

In addition, in the existing technology, the investment cost of a governance point is about 100 million yuan, and there is a problem that the investment cost is relatively large
