A device for observation and removal of floating algae drift

Abstract

The invention relates to the field of water bloom algae treatment equipment, in particular to a floating algae drifting observation and removal device. The device comprises a floating algae drifting observation platform arranged on an open water body, a floating algae removal unit and a control unit; the floating algae removal unit includes a circulating unit consisting of a first water pump, a water return pool, a filter screen mechanism, multiple sets of water inlet pieces and a water return piece; all the water inlet pieces are arranged in common gathering points of each floating algae of an off-shore water body in a floating manner; water inlet holes are formed in the middle parts of the water inlet pieces; the water return piece is annular, and is suspended in water around the water inlet pieces; the water inlet pieces are connected with a water inlet of the first water pump through water inlet pipelines; a water outlet of the first water pump is opposite to the water return pool; the filter screen mechanism is provided with a filter screen; the filter screen is arranged between the water outlet and the water return pool; the water return pool is communicated with the water return piece through a water return pipeline; and multiple water return holes are formed in the water return piece. The device uses the floating algae drifting observation platform for judging the moving direction and speed of the algae on the water, and effectively removes the algae in the floating algae gathering area to prevent large-scale outbreak of floating algae water bloom.

Description

technical field [0001] The invention relates to the field of water bloom algae treatment equipment, in particular to a floating algae drift observation and removal device. Background technique [0002] In most water bodies with excessively high nutrient salt concentration, algal blooms in late spring and early summer multiply rapidly, and form a thick layer of blue-green, fishy-smelling foam on the water surface, which is called "water bloom". Large-scale blooms of cyanobacteria are known as "green tides" (or red tides if they occur in the ocean). The growth cycle of algal blooms is short, and their death will release a large amount of nutrient salts, causing water quality to deteriorate; the decomposition of organic residues will quickly deplete the oxygen in the water body, resulting in the death of a large number of fish and shrimp. In addition, some species of cyanobacteria (such as Microcystis) also produce toxins (referred to as MC). In addition to being toxic to fis...
