Abstract
The invention discloses a purifying ball for algae removal. The invention is characterized in that a mixture of auxiliary materials and probiotics is placed in the inner part of the purifying ball, a layer of water treatment agent is covered on the surface of the mixture, and the outermost layer surface of the purifying ball for the algae removal is adhered with a layer of algae removing agent, wherein the probiotics is a microbe active bacteria agent compositely cultured by a photosynthetic bacteria, a nitrifying bacteria and an actinomycete; and the auxiliary materials comprise kelp residues, peel powders, humic acid, bentonite, skins of barleys, bean pulp, molasses, amino acid, salt and water. When the purifying ball is put into water, the algae removing agent encounters water to fast extend to remove the algae in step one; the water treatment agent spreads to play a role in step two; and the internal auxiliary materials and the probiotics treat the ruined algae residuals and nutrient-rich substances at the bottom of water. In this way, primary ball injection can remove the harmful algae and purify water body as well as maintain the ecological balance of the water body.
Description
Technical field

Technical solution technical scheme that problem adopts of the present invention is: described purifying ball for algae removal, inside is the mixture of auxiliary material and probiotic bacterium, at mixture surface parcel one deck water quality treatment agent, attach one deck algae agent for killing at the purifying ball for algae removal outermost surface, wherein said probiotic bacterium is the compound cultured microorganism live bacteria agent of photosynthetic bacteria, nitrifier and actinomycetes, and described auxiliary material comprises kelp residue, fruit peel powder, humic acids, wilkinite, wheat skin, beans pool, molasses, amino acid, salt and water.
Described water quality treatment agent is an inorganics diatomite.
Described algae agent for killing is that tongue is clean
Described photosynthetic bacteria is a Rhodopseudomonas palustris, and Rhodopseudomonas palustris nutrient solution prescription is: potassium primary phosphate 0.3-0.6 gram, sal epsom 0.3-0.6 gram, sodium acetate 2.0-5.0 gram, Yeast diffusion juice 1.0-2.5 gram, sterilization seawater 600-1200 milliliter.
Described nitrifier nutrient solution prescription is: in every 1000ml sterilized water, and sodium bicarbonate 1.0-3.0 gram, Sodium Nitrite 1.80-2.96 gram, yellow soda ash 0.20-0.56 gram, sodium chloride 0.20-0.48 gram, potassium primary phosphate 0.03-0.06 gram, magnesium sulfate heptahydrate 0.03-0.06 gram, seven water sulfurous acid iron 0.03-0.06 gram, glycerine 1.8-3.6 gram, yeast extract 0.9-2.2 gram.
Described actinomycetes nutrient solution prescription is: in every 1000ml water, and Zulkovsky starch 1.2-2.8g, saltpetre 0.05-0.2g, dipotassium hydrogen phosphate 0.02-0.1g, sodium-chlor 0.02-0.1g, sal epsom 0.02-0.1g, ferrous sulfate 0.0005-0.002g, agar 1.2-2.8g.
Described each composition quality percentage ratio is---kelp residue 8-10%, fruit peel powder 20-25%, humic acids 7-9%, wilkinite 20-30%, wheat skin 1-3%, beans pool 1-3%, diatomite 1-3%, the clean 1-2% of tongue, molasses 1-2%, amino acid 8-10%, salt 0.8-0.95%, bacterium liquid 3-4%, water 5-6%.
The beneficial effect that the present invention can bring is:
(1) the disposable problem of killing algae, removing algae and purification of water quality that solved;
(2) greatly reduce the required input of improvement, saved cost.
Embodiment
Described purifying ball for algae removal, inside is the mixture of auxiliary material and probiotic bacterium, at mixture surface parcel one deck water quality treatment agent, described water quality treatment agent is an inorganics diatomite, attach one deck algae agent for killing at the purifying ball for algae removal outermost surface, described algae agent for killing is that tongue is clean, wherein said probiotic bacterium is the compound cultured microorganism live bacteria agent of photosynthetic bacteria, nitrifier and actinomycetes, and described auxiliary material comprises kelp residue, fruit peel powder, humic acids, wilkinite, wheat skin, beans pool, molasses, amino acid, salt and water.
Described photosynthetic bacteria is a Rhodopseudomonas palustris, and Rhodopseudomonas palustris nutrient solution prescription is: potassium primary phosphate 0.3-0.6 gram, sal epsom 0.3-0.6 gram, sodium acetate 2.0-5.0 gram, Yeast diffusion juice 1.0-2.5 gram, sterilization seawater 600-1200 milliliter.Because photosynthetic bacterium has the metabolic type that changes flexibly along with the variation of growth conditions, so it can handle the organic waste water of up to ten thousand milliliters of BOD concentration.Generally, the BOD5 clearance can reach 95%, even reaches 98%.Rich in proteins (65%) and vitamin B group in the photosynthetic bacteria cell have great practical value simultaneously, can be used as animal and fowl fodder and fishes and shrimps ear material etc.
Described nitrifier nutrient solution prescription is: in every 1000ml sterilized water, and sodium bicarbonate 1.0-3.0 gram, Sodium Nitrite 1.80-2.96 gram, yellow soda ash 0.20-0.56 gram, sodium chloride 0.20-0.48 gram, potassium primary phosphate 0.03-0.06 gram, magnesium sulfate heptahydrate 0.03-0.06 gram, seven water sulfurous acid iron 0.03-0.06 gram, glycerine 1.8-3.6 gram, yeast extract 0.9-2.2 gram.Deleterious chemical substance in the water can be decomposed removal as ammonia and nitrous acid etc. because of nitrifier, so can purify water, nitrobacteria is brought into play best results under water quality pH neutrality, weakly alkaline environment.
Described actinomycetes nutrient solution prescription is: in every 1000ml water, and Zulkovsky starch 1.2-2.8g, saltpetre 0.05-0.2g, dipotassium hydrogen phosphate 0.02-0.1g, sodium-chlor 0.02-0.1g, sal epsom 0.02-0.1g, ferrous sulfate 0.0005-0.002g, agar 1.2-2.8g.Actinomycetes can absorb the amino acid that photosynthetic bacterium produces, and produce antibiotics.This microbiotic can effectively suppress pathogenic bacteria, fights for material required when being harmful to mould and bacterial reproduction, thereby suppresses its propagation, and creating is of value to other beneficial microorganism survival environment.
Described each composition quality percentage ratio is---kelp residue 8-10%, fruit peel powder 20-25%, humic acids 7-9%, wilkinite 20-30%, wheat skin 1-3%, beans pool 1-3%, diatomite 1-3%, the clean 1-2% of tongue, molasses 1-2%, amino acid 8-10%, salt 0.8-0.95%, bacterium liquid 3-4%, water 5-6%.
The present invention in use, when only needing drop into purifying ball in the water, the first step, the algae killing agent meet water rapidly expansion kill algae; In second step, water quality treatment agent scatters and plays a role; In the 3rd step, inner auxiliary material and probiotic bacterium are handled residual body of algae that is destroyed and water-bed rich nutritive material in the bottom of water, and such pitching both can the kill harmful algae, also can purifying water body, kept the water ecology balance.
