Description
Technical field
The present invention relates to cyanobacteria modified material fields of lossing.It is more particularly related to which a kind of Quick Coagulation is gone
Cyanobacteria modified soil and preparation method thereof.
Background technique
Nearly ten years, poisons in freshwater cyanobacterial bloom in China's shows a wide range of, high frequency time, high-biomass spy
Sign, causes the unbalance of aquatic ecosystem structure and function, it is this it is unbalance will directly or indirectly influence human health, become
China is at present and a very long time in future needs the great water environmental problems that face.Worldwide, cyanobacterial bloom
Ascendant trend is presented in event occurrence rate, and distribution is in expansion trend；In some areas, annual cyanobacterial bloom breaks out and holds
It is continuous to have become normality.The eutrophic extent (such as nitrogen, phosphorus concentration) in China lake is more obvious than most Europe and North America lake
Seriously, taking action in lake, (restoration of the ecosystem) is often synchronous with action (pollution source apportionment) outside lake to be carried out, therefore controls cyanobacterial bloom
Generation, the difficulty restored and rebuild aquatic vegetation are much greater.
Nutritive salt substantially cut down be cyanobacterial bloom control fundamental way, but aquatic ecosystem nutritive salt is cut down it is anti-
Should be relatively slow, the extension of phase is administered, results even in the conversion for producing seed culture of viruses class, therefore the simple reduction by nutritive salt is in a short time
It is hard to work.The cyanobacterial bloom in the numerous lakes in China still behaves as normalization and sudden, and being badly in need of exploitation can effectively control
The methods and techniques of the cyanobacterial bloom of sudden/normalization are made, and prevent its diffusion in waters.It develops and is used for as a result,
The cyanobacteria material and preparation method thereof that goes of Quick Coagulation seems very urgent necessity.
Summary of the invention
It is an object of the invention to solve at least the above problems, and provide the advantages of at least will be described later.
Cyanobacteria modified soil and preparation method thereof is removed it is a still further object of the present invention to provide a kind of Quick Coagulation, is mentioned
The Quick Coagulation of confession goes cyanobacteria modified soil to have performance stabilization, except the fast response time of algae water purification, to the impurity in sewage
With certain anti-interference ability, when use, is easy to operate；Provided Quick Coagulation goes cyanobacteria modified soil quick
The transparency of water body is improved, water body organoleptic properties are enhanced；Provided Quick Coagulation goes cyanobacteria modified soil that can efficiently go
Cyanobacteria, moreover it is possible to achieve the effect that Quick Coagulation；Provided Quick Coagulation goes cyanobacteria modified soil to be very suitable to make on a large scale
It is standby, to go the Large scale field application of cyanobacteria material to provide solid technical support.
