Description
Technical Field
The invention relates to the technical field of environmental protection, and particularly relates to a river course water treatment agent.
Background
Eutrophication is a phenomenon of water pollution caused by excessive content of nutrient substances such as nitrogen and phosphorus, and excessive nutrient elements such as nitrogen and phosphorus enter natural water bodies along with the movement of human beings, so that the water bodies are eutrophicated. The blue algae is a common algae in water and has floatability and algae odor. In summer, a large amount of blue algae can be suspended or accumulated on the surface layer of eutrophic water body, so that the water body is anoxic and a large amount of fishes die, and the water body is polluted after the blue algae die and is decomposed.
The current common methods for treating the blue algae harm comprise: 1. removing blue algae by a manual fishing method; 2. setting an artificial fence for blocking; 3. feeding algae-eating animals and plants such as fish, snails, shellfish and the like to control the eutrophication of the water body; 4. sprinkling biological preparation.
The method has certain effect on treating the blue algae in the small water body, but the effect is very limited, and the reason is that: the blue algae body is smaller and fast to propagate, and is mostly suspended on the surface layer of the water body, the blue algae piled on the bank can be salvaged, and the blue algae dispersed in the water is extremely low in salvage efficiency or cannot be salvaged at all. Although the method of fencing, putting in fish and the like is very beneficial to ecological restoration of water and reduction of the number of blue-green algae, the method has the disadvantages of large investment, large implementation difficulty and unsatisfactory algae inhibition and deodorization effects. The simple splashing of biological agents to improve water quality cannot inhibit the growth of blue algae or eliminate the odor of blue algae. The existing blue algae treatment method has great investment, but the effect is more and more successful, so the existing blue algae treatment method has obvious defects and shortcomings.
