Cyanobacterial bloom control agent and application thereof

Abstract

The invention discloses a cyanobacterial bloom control agent. Copper ions are complexed and adsorbed on the surfaces of cyanobacteria cells to prepare cyanobacteria bloom control agent-cyanobacteria copper, the copper ions are insoluble in water but adsorbed on the surfaces of the cyanobacteria cells, and the cyanobacteria copper is adhered on the surfaces of the cyanobacteria blooms, sinks and floats in water, diffuses and kills the cyanobacteria cells due to good affinity with cyanobacteria. Copper ions of the product are insoluble in water, have little influence on the environment, are longin time effect, can cause slow death of cyanobacteria cells, can also act on cyanobacteria provenance at the bottom of a water body, reduce the quantity of the cyanobacteria provenance and are beneficial to control over excessive proliferation of cyanobacteria.

Description

technical field [0001] The invention belongs to the technical field of cyanobacteria bloom control, and in particular relates to a cyanobacteria bloom control agent, which can be used to treat cyanobacteria blooms in aquaculture ponds and surface water bodies. Background technique [0002] In recent decades, the scope and frequency of harmful cyanobacterial blooms have increased significantly worldwide. It is expected that due to climate warming, rising carbon dioxide concentrations, and continued eutrophication, the occurrence and development of algae blooms in the next few decades is predicted may be expanded further. There are different degrees of eutrophication in a large number of surface water environments in my country. It is an urgent need to protect water resources to control the excessive proliferation of algae and improve the environmental quality of lakes, rivers and aquaculture water bodies. [0003] my country's aquaculture production accounts for 71% of the w...

Problems solved by technology

[0008] Although copper sulfate is fast in killing algae, it mainly has the following disadvantages and hazards: (1) copper sulfate will diffuse widely after being dissolved in water, and the dosage is large and the time limit is short, and it will affect aquatic animals such as fish and shrimp; The lethality of algae is non-selective, and beneficial algae will also be killed; (3) the algae dies and decomposes aerobically, and at the same time the function of photosynthetic oxygen production in the water body is lost, which can easily cause the death of fish and shrimp due to hypoxia; (4) a large number of algae The toxin released by death endangers aquatic animals; (5) water quality declines
