Abstract

The invention relates to a deoiling powdery blue-green algae treatment agent which is prepared from the following raw materials in parts by weight: 14-18 parts of tetra calcium aluminoferrite, 5-7 parts of hydroxyethyl cellulose, 10-15 parts of filter powder, 10-14 parts of expanded graphite, 20-24 parts of vermiculite, 14-19 parts of calcium carbonate, 3-5 parts of ligneous calcium sulphonate, 6-9 parts of titanium dioxide, 8-12 parts of iron oxide red powder, a proper amount of water, 13-16 parts of tea dregs, 13-16 parts of astragalus smicus and 3-4 parts of an adsorption auxiliary. By using astragalus smicus, the deoiling powdery blue-green algae treatment agent after high-temperature treatment is not only good in suspension property and good in adsorption on blue-green algae, but also is high in nitrogen content of astragalus smicus; the n/p ratio of water quality can be improved, the growth of blue-green algae is inhibited, and by match of expanded graphite and vermiculite, the deoiling powdery blue-green algae treatment agent can adsorb blue-green algae, is good in suspension property and easy to gather and fish. Moreover, the expanded graphite is good in oil absorption. By adding titanium dioxide and iron oxide red powder, ecological balance is not affected while the blue-green algae are killed by catalytic oxidation.

Description

One is deoiled powdery blue algae treatment agent and preparation method thereof

Technical field

The present invention relates to the treatment agent of sewage disposal and environmental improvement, particularly relate to one and to deoil powdery blue algae treatment agent and preparation method thereof.

Background technology

Blue-green algae is algae bio, cries blue-green algae again.In all algae bios, blue-green algae be the most simply, the most original one.The phenomenon destroying the eubiosis because water resource environment extremely badly causes blue-green algae amount reproduction is called " blue-green alga bloom ".Blue-green alga bloom can cause fishes and shrimps dead, causes water pollution, causes serious impact to the production of the mankind and life.In addition, cyanophycean toxin also can the health of seriously harm humans.In the event that the states such as the U.S., Japan, Australia, Brazil all have report to cause fish domestic animal and people to be poisoned to death because of Algae toxins.China's numerous water body in lake blue-green alga bloom occurrence frequency is high, and algae bio amount is huge, and product virulence is strong.Therefore, a kind of method of seeking long-acting, economic and safe prevention and corntrol blue-green alga bloom is very urgent according to domestic and foreign literature report, and existing blue-green algae administering method divides physics, chemistry and the method such as biological.

Chemical process utilizes algicide to carry out except algae, simply, easy, lake surface view is not affected, but because it can cause secondary pollution, adverse influence is had to zoobenthos and zooplankton, and consequent dead algae can produce secondary pollution as new source of pollution, is unfavorable for the use of tap water, can raise lakebed simultaneously, acceleration lake is aging, paludification, instead of a kind of suitable effective minimizing technology.

Physical method is as passed through method for floating, and from water, pull blue-green algae or centrifugal out, it is treated both principal and secondary aspect of disease, water quality and hydrobiont population are had no adverse effect, non-secondary pollution, and the pollutent in water outlet can be carried, but this method cost is high, is not suitable for large-area applications, need to adhere to for a long time removing; In addition, lake surface view is had a certain impact.

Biological method significantly can reduce the pollutent in water, and within the regular hour, keep the cleaning of water body, does not affect lake surface view.But its time is long, DeGrain, the pollutent in lake fundamentally can not be removed; Lake biotic population structure, species diversity are affected; Dead algae can produce secondary pollution as new source of pollution, and raises lakebed, and acceleration lake is aging, paludification.

The means of the bacterial control of new development because at present also unresolved it safety and operational issue and droping.Other biological method controls and algae competition as filtered-feeding fish, is not very effective or safe not to the green tide of large-scale outburst.

Application business flocculation agent (as polymerize aluminum chloride and poly-ferric chloride) removes marine alga in natural water, it exists safety problem such as the aluminium in polymerize aluminum chloride can cause cerebral nervous system damage etc., and flocculant usage is very large, cost is high, which also limits it and uses.

Although there are many methods of administering blue-green algae at present, each method has respective relative merits, can not be used widely.The research of current blue-green algae and administer the serious present situation that relative blue-green algae pollutes and be also nowhere near, so all carrying out all kinds about the improvement of blue-green algae or research in worldwide.

Summary of the invention

The object of the present invention is to provide one to deoil powdery blue algae treatment agent and preparation method thereof, this treatment agent has no side effect, and oil absorbency is good, and suspension is good, to the excellent adsorption of blue-green algae, kills blue-green algae fast, and effect is permanent.
