Description
Technical field
The invention belongs to the water pollution control field, be specifically related to a kind of agent for removing algae from aquatic system and preparation method thereof.
Background technology
Blue-green algae (blue green Algae) is that a class is produced the photosynthetic prokaryotic organism of oxygen, claims cyanobacteria (cyanobacterium) again, belongs to Cyanophyta.Blue-green algae is one of normal composition in the water body, but behind excessive growth and breeding, will form green tide, also claims wawter bloom.Blue-green alga bloom has become worldwide environmental hazard, in the lake of China 60% the eutrophy phenomenon is arranged, and will be subjected to the influence of green tide.Administer the algae method and comprise chemistry, methods such as physics and biotechnology.Chemical method such as algicide etc. have had less concern, because algicide can affect other biological, algae also can discharge the algae toxin.Physical method is as by flotation, and aeration such as salvages or centrifugal at the method, can non-secondary pollution deal with problems, still because the too little difficult removal water of algae causes efficient low, high cost etc. and make this method also not enough practical.Method biological and restoration of the ecosystem is all right, be not to get preferably effect in the very big zone, but powerful engineering reserve and relative cycle than growing make it can't use blue algae bloom.The bacterial control means of new development are because present unresolved its safety and operational issue and droping also.Other biological method is not very effective such as the control of hello fish and algae competition.Using commerce drops because of safety and economic cause in natural water with flocculation agent (as polymerize aluminum chloride and poly-ferric chloride).
Recently, along with more and more seriously reaching weather condition, body eutrophication warms, blue-green alga bloom is outburst in the large-area waters of China such as Taihu Lake, Dian Chi, Chaohu etc. every year, country and local great attention have been caused, scientific and technological circle more patent and research article have occurred also to this number of research projects.It is a wherein very important and effective research direction that mineral material is applied to blue-green algae improvement.
It is more to utilize imvite to administer the research of algae in the clay mineral.But it is less relatively to utilize kaolin to administer algae, but because kaolin and polynite character have many similarly, as all being the lamella mineral, flocculating effect appearance etc. is arranged all.So, the research that utilization method in polynite is applied in the kaolin is a lot, as utilizes polymerize aluminum chloride, chitosan, acid, tensio-active agent polyene acid amides, cetyl trimethylammonium bromide, APG quaternary ammonium salt, trialkyl polyoxyethylene groups three quaternary ammonium salts etc.But administering algae for kaolin, some method do not have very big effect.As administer red algae, and Japan thinks that for the field kaolin does not have obvious effect, and but, Yu Zhiming thinks that some kind in the kaolin has the ability of the flocculation red tide plankton higher than imvite, and wherein galapectite is a kind of.After a large amount of algaes appear in U.S. Chesapeake Bay, utilize exactly kaolin to remove red tide plankton Prorocentrum micans (Prorocentrum sp) and brown born of the same parents algae (Chattonella), after its chlorophyll content clearance 2.5 hours with four days after utilize the living body fluorescent technology to indicate, discovery reaches about 99%, 92%.And the kaolin after the sour modification can not significantly improve its ability of removing red tide plankton.As seen, controlling algae aspect,, not necessarily be suitable for for kaolin to imvite modified method.
Summary of the invention
It is the Cyanobacterial scavenger and preparation method thereof of carrier with kaolin that the object of the invention is to provide a kind of, and it is remarkable that the Cyanobacterial scavenger of this method preparation is removed the blue-green algae effect.
To achieve these goals, technical scheme of the present invention is: a kind of Cyanobacterial scavenger take kaolin as carrier is characterized in that it is by Ce (NO

3Dropping sodium solution in the solution, flocculent deposit appears and after, continue to stir 25～35min, get the flocculent deposit mixed solution;
3) in the flocks mixing solutions, add kaolin, stir 25～35 minutes after-filtration, dry (drying is 10～15 hours under 90～100 ℃), obtaining with kaolin is the Cyanobacterial scavenger of carrier.
The invention has the beneficial effects as follows:
1, utilizes kaoline loaded cerium to form efficient flocculant, remove the blue-green algae in the water body.After this Cyanobacterial scavenger joins the water body of algal suspension pollution, blue-green algae is had good throwing out, can make the rapid flocculation sediment of algae such as blue-green algae in the water body to bottom, natural death, it is remarkable to remove the blue-green algae effect, very helps suffering the comprehensive regulation of blue-green alga bloom polluted waters.It also has good inhibitory action to blue algae growth simultaneously, except algae effect longer duration.And stable in properties of the present invention, to the person poultry harmless, low, the non-secondary pollution of cost.
2, technology of the present invention is simple, and is easy to operate; Adaptive faculty is strong, can be widely applied to the various waters that polluted by blue-green algae.The puzzlement that polluted by blue-green alga bloom in the many lakes of China at present has a strong impact on the Human's production life, and the present invention pollutes, improves water quality and have good effect for administering blue-green algae, has a extensive future, and meaning is very great.
