Description

Blue-green algae treatment device and method Technical field

The invention relates to the field of ecological protection, in particular to a blue algae treatment device and method.

Background technique

In some nutrient-rich water bodies, some cyanobacteria often multiply in summer, and form a layer of blue-green and fishy scum on the water surface, called "blooms". Large-scale outbreaks of cyanobacteria are called "green". "Tide" (the one that erupts in the ocean is called "red tide"). The green tide causes the deterioration of water quality, and in severe cases, it exhausts the oxygen in the water and causes the death of fish. What's more serious is that some species of cyanobacteria also produce toxins. For example, Microcystins produces microcystins (MCs). About 50% of green tides are found to contain a large amount of MCs. MCs can directly cause poisoning to fish, humans and animals. Existing blue-green algae treatment methods are usually to drive a treatment boat into the water body where blue-green algae is erupted to salvage and collect the blue-green algae. It needs to be manually entered into the ship's body to work, so that the operator is surrounded by green tides, and the operator needs to endure the stench emitted by the blue-green algae. , And it is easy to come into contact with a large number of MCs, which may cause poisoning of workers.
