Description
Technical field
The present invention relates to environmental protection technical field, is specifically related to a kind of multi-functional composite alga removing granule.
Background technology
A large amount of sanitary sewages rich in N, P and industrial wastewater discharge are pooled to ocean to rivers and lakes, and water body occurs
Eutrophication, causes algae and the rapid amount reproduction of other planktons, result in serious environmental hazard, and this phenomenon is in recent years
Come in the frequently generation such as each big small lakes of China, river and marine site.The amount reproduction of algae not only seriously hinders the water surface and leads to
OK, and heavy damage water body environment, ecological environment security is endangered.
Jing long-term research and practice, define with physics, chemistry, the biological main algae removal technology of three classes as means.
Physical can be divided into removal method and kills method, the former be by certain physical method directly remove frustule or
Its content is reduced, mainly algae, air floatation alga removing and activated carbon adsorption etc. is filtered except algae, excessively including water diversion and renewal, machinery；The latter is to make
The algae in water body is directly or indirectly killed with physical means, main method has shading treatment, electrolysis except algae, ultraviolet irradiation and surpasses
Sonicated etc..Physical can effectively remove algae, will not produce secondary pollution, but incur great expense, so can only
For small size pond and the local waters of big water body.
Chemical method is mainly chemistry and kills method.Chemistry kills method generally by medicament is added, and suppresses the physiology of frustule
Function, destroys the structure of frustule, makes frustule inactivation even disintegrate, and so as to reach algae is killed.Major pharmaceutical agent has Strong oxdiative
Agent (liquid chlorine, hydrogen peroxide, ozone, potassium permanganate etc.), copper sulfate etc..Chemical method is except algae effect is good, low cost, but specificity
Difference, and secondary pollution is serious.
Bioanalysises refer to using microorganism, plant and animal control algae except algae.Microbial method is by adding microorganism drop
Nutrient substance in Xie Shui, or add and bite algae microorganism and directly degrade frustule.Plant method is manually to plant Aquatic Higher Plants, right
Water nutrition is controlled；On the other hand be by the allelochemical of Plant emission to suppress water body in algae.Animal law
Aquatic animal such as filter-feeding fish is typically put in a suitable place to breed come the algae in water body that eats.Biology is except the ecological security of algae is high, cost
Low, often slowly effect, action period are long, though wherein algae instant effect is bitten in microorganism, but ecological security remains to be discussed.
Existing algicide is not thorough except dry function, and easily water body is polluted, and is not only unfavorable for the life of fish, shrimp, Eriocheir sinensiss
It is long, but also the statement of fish, shrimp, Eriocheir sinensiss can be seriously threatened, and then human life and health is threatened, therefore, research and development one kind can either be thorough
While algae is removed at bottom, moreover it is possible to reduce water pollution, the concentration of trace element in water body is effectively improved, promote fish, shrimp, the health of Eriocheir sinensiss
The algicide of growth is extremely urgent.
The content of the invention
Present invention solves the technical problem that being to provide a kind of multi-functional composite alga removing granule, local concentration is big, can
It is enough thoroughly to remove algae, moreover it is possible to reduce water pollution.
The technical scheme is that：A kind of multi-functional composite alga removing granule, count by weight percentage, be by it is following into
It is grouped into：0.08-3% algicide, 0.1-2% SODIUM PERCARBONATE crystal, 2-6% lithium magnesium silicates, 2-3% potassium silicates, 20-30% water
Property polyurethane coating, 10-30% water-swellable compositionss, compound foaming agent 0.1-0.3%, Herba basellae rubrae potato extract 0.2-0.5%,
Phyllanthus simplex Retz． extract 0.1-0.2%, micropore ceramics powder 2-5%, balance of water-soluble polymer.
Further, it is any during the water-swellable compositionss are by water-swellable resin, starch, cellulose and natural gum
One or more composition.
Further, the water-soluble polymer is selected from acrylic resin, urethanes, polysiloxanes.
Further, the compound foaming agent is the saturating alcohol of Oleum Terebinthinae, azodicarbonamide, tea saponin by any weight ratio
Mixing.
Further, the aperture of the micropore ceramics powder is 1-20nm, and diameter of particle is 1-100 μm, micropore ceramics powder tool
There are preferably absorption and Water warfare effect.
Further, the algicide is inorganic algicide or organic algicide.
Further, the inorganic algicide in Red copper oxide, Zinc Oxide, the titanium dioxide any one or arbitrarily
Two or more combinations.
Further, organic algicide is selected from DBNPA, the bromo- 2- nitros second of 2,2- bis-
It is any one in the chloro- 2- n-octyls -3- isothiazolone of alcohol, 4,5- bis-, tetrakis hydroxymetyl phosphonium sulfuric, DDAC
Plant or arbitrarily two or more combinations.
A kind of multi-functional composite alga removing granule, its preparation method is：

Compound, it is standby；
The preparation method of the Herba basellae rubrae potato extract and Phyllanthus simplex Retz． extract is：Fresh Herba basellae rubrae potato is cleaned, with water or
Person's ethanol is extracted for solvent, and the extract concentration for obtaining is purified and is spray-dried, that is, obtain Herba basellae rubrae potato extract；By yellow pearl
Sub- grass dry product is soaked in water, and is placed in multi-function extractor and is extracted with water, and the extracting solution concentration for obtaining is purified and spray dried
It is dry, that is, obtain Phyllanthus simplex Retz． extract；
(2) SODIUM PERCARBONATE crystal, lithium magnesium silicate, potassium silicate are crushed, with compound foaming agent, Herba basellae rubrae potato extract, Huang Zhu
Sub- grass extract, micropore ceramics powder, algicide mixing, it is stand-by as core body；
(3) by above-mentioned core body aqueous polyurethane coating coating, then with the secondary clothing of water-swellable compositionss bag, then with water-soluble
Property polymer Bao Sanci clothing, three layers of coatings may each be by fluidized bed coating or other similar coating methods, that is, obtain
It is described except algae granule.
Further, the size except algae granule is 3-6mm.
Using method：To directly be thrown in the waters of algae except algae granule, injected volume is：0.05-5g/m2, according to
Algal grown density size adjustment its consumption.
Beneficial effects of the present invention are：The present invention is by the way that algicide is mixed with SODIUM PERCARBONATE crystal, lithium magnesium silicate, potassium silicate
Close, then wrapped up with three layers of coating of outside, after putting in water, the water-soluble polymer on top layer dissolves, intermediate layer
Water-swellable compositionss meet the aqueous polyurethane coating of water-swellable compressing internal layer, and the algicide slow release for making middle parcel goes out
Come, recycle lithium magnesium silicate to be dissolved in the colloidal property having after water so that algicide is difficult to be dispersed in water rapidly, but includes
It is higher to ensure its local concentration in water in colloid, except algae effect it is good, moreover it is possible to the less injury to other organisms in water,
In addition, SODIUM PERCARBONATE crystal has functions that oxidant, there is certain inhibitory action to algal grown, it can also produce oxygen
Gas, has bleaching, sterilization, sterilization etc. to act on, and can improve water quality；Micropore ceramics powder therein has preferably absorption and Water warfare
Effect；Herba basellae rubrae potato extract and Phyllanthus simplex Retz． extract have facilitation to the aquatic animals such as the fish and shrimp in water body growth；This
Bright preparation except algae particle form it is unique, inputs can be oriented, local concentration greatly, can either thoroughly remove algae, moreover it is possible to reduce
Water pollution.
