CN104402084A - TiO2 hollow microsphere blue algae processing agent and preparation method thereof - Google Patents

Abstract

A TiO2 hollow microsphere blue algae processing agent is composed of the following raw materials in parts by weight: 12 to 16 parts of bamboo charcoal powder, 2 to 4 parts of TiO2 hollow microsphere, 0.9 to 1.2 parts of polyhexamethylene guanidine, 1 to 2 parts of dibromohydantoin, 14 to 16 parts of iron ore tailings, 14 to 18 parts of cotton seed cake, 15 to 20 parts of polymeric ferric sulfate, 7 to 9 parts of maleic acid, 5 to 7 parts of sodium hydrogen sulfite, 3 to 5 parts of hydrolytic polymaleic anhydride, 5 to 7 parts of calcium acetate, a proper amount of water, and 5 to 7 parts of absorbent aid. The cotton seed cake is added, and thus the blue algae processing agent has an antibacterial effect. TiO2 hollow microspheres are added to kill blue algae and bacteria, and organic matters can also be decomposed by the hollow microspheres. The added iron ore tailing has an oxidizing effect and thus can enhance the blue algae killing effect. Moreover the processing agent also has a flocculating effect, is capable of killing blue algae chemically, can inhibit and kill blue algae for a long term, can purify the water, prevent water oxygen deficiency, and protect other organisms, and treats both the symptoms and the roots.

Description

A kind of TiO 2tiny balloon 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 a kind of TiO ₂tiny balloon 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 a kind of TiO ₂tiny balloon blue algae treatment agent and preparation method thereof, this treatment agent can catalyzed oxidation killing blue algae, bacterium etc., can also decomposing organic matter; Can also purify water, anoxic in anti-sealing, protection other biological, has the effect for the treatment of both principal and secondary aspect of disease.
