Description
Technical field
The present invention relates to biological environmental production material field, specifically is a kind of method of utilizing blue-green algae residue to prepare nano active carbon spheres.
Background technology
Along with the urban industry process is accelerated, environmental pollution increasingly sharpens, and the caused harmful blue-green alga bloom of eutrophication has become the environmental problem of domestic and international common concern.Contain a large amount of algae in eutrophic lake, the reservoir water, contain algae amount be generally every liter tens thousand of to tens million of.The general physics that adopts, methods such as chemistry are taken emergency measures to it when blue-green algae breaks out in a large number, as artificial salvaging, machinery is salvaged, coagulating sedimentation, coagulation air-float etc., but when pulling blue-green algae out, all brought a same problem, how to have handled or disposed these high pollution algae-residues.Simultaneously, there are many water supply plants of handling algae-containing water in China, and direct filtration is not generally adopted in the water treatment of giving of algae-containing water, should pass through coagulating sedimentation or coagulation air-float earlier before filtering, and promptly uses coagulation-air supporting-filtration-disinfectant water purification treatment technology.Scum silica frost amount after this art breading is big, Pollutant levels are very high.The algae-residue volume is generally handles about 0.04% of the water yield, and water ratio is 95-97%.The BOD5 average out to 5203mg/L of algae-residue, COD Cr average out to 15800mg/L, the content of total arsenic, total zinc, total cadmium, total plumbous, total iron and total nitrogen, total phosphorus, aluminium etc. is all very high.Preceding 8 kinds of Pollutant levels such as the above-mentioned suspended solids in the algae-residue be sewage enter the urban discharging pipeline maximum permissible concentration 19-204 doubly, algae-containing water after treatment, the algae toxin of water outlet has reduced 60% than water inlet.The algae toxin that reduces comprises that cell is interior and extracellular, and two kinds of algae toxin all enter in the algae-residue, and the content of algae toxin is also very high in the algae-residue.Therefore, algae-residue not only can not enter water body, also should not enter urban discharging pipeline, should suitable in addition processing or disposal.
Processing to algae-residue at present mainly comprises following several measure:
Extract physiologically active substance: blue-green alga extract is found has the antimicrobial effect, data shows, the methanol extract of Tychonema bourrelly, phanizomenon flos-aquae and Cylindrospermopsisraciborckii has fungistatic effect preferably, and the water extract of Microcystis aeruginosa and T.Hourrellyi also has tangible bacteriostatic action; The blue-green algae that has is found in screening has antiviral activity, in their blue-green alga extract that screened of discoveries such as Rinehart, all has a herpes II C-type virus C activity more than 5%, the activity with anti respiratory syncytial virus more than 5% is also arranged in addition, but algae is of a great variety in the algae-residue, and the structure of these active substances is still indeterminate, and poisonous mostly, it is difficult to be used for medicine, needs further research.Produce biogas: studies show that 5000t (dried algae amount) produces more than 180 ten thousand m
3Biogas, methane content is 64.91% in the biogas.But blue algae fermentation produces biogas also exists many problems, utilization ratio was very low when blue algae fermentation produced biogas, the foundation of economical and efficient zymotechnique and the design of anaerobic ferment devices, the quick startup of fermentation and the utilization of fermentation resistates fertilizer also are the emphasis of research, and will be further analyzed and handle Microcystin in the fermentation residue is residual.Make organic fertilizer: Japan is to the measure of blue-green algae recycling, mainly be as organic fertilizer with algae, its fertilizer efficiency is better than general chemical fertilizer, nitrogen, phosphorus, potassium content all are higher than vegetalitas organic fertilizer such as soya-bean cake, Herba Astragali Melilotoidis (Herba Astragali Sinici), do not contain heavy metal in the blue-green algae to crop and human body harmful, can contaminated soil after the use.1992, the dehydration Microcystis aeruginosa of Japan was all realized fertilizerization, annual production 120-180t.After Microcystis aeruginosa was realized recycling, its processing costs had descended 30%, but nearest studies show that, the algae toxin of dried content has certain injury and mutagenesis to farm crop in the algae-residue, food safety is existed potential threaten.The system biofuel: according to the club numeral of world oil, the per hectare soybean can produce 450 liters of biofuel, and palm can produce 6000 liters, and the per hectare blue-green algae can produce 90,000 liters of biofuel, but also can plant on ground as farm crop.And blue-green algae biofuel conversion ratio accounts for 50% of its weight, and some enterprises attempt producing blue-green algae in plastics are fluffy greatly, and cost is higher like this, and open-air plantation is unique selection that reduces cost.But it is less that the blue-green algae of salvaging out from Taihu Lake contains lipid material, has only 0.26%, extracts grease making biofuel and do not have feasibility from blue-green algae.In actual applications, the blue-green algae recycling fails to obtain industrialization development and large-scale application for many years always, and problem mainly is present in the following aspects: scale is broken out, the salvaging amount big, difficulty, broken wall cost height and algae the toxin remains dewater.
Summary of the invention
The invention provides a kind of method of utilizing blue-green algae residue to prepare nano active carbon spheres, a large amount of algae-residues can be efficiently handled and algae-residue can be utilized again simultaneously, turn waste into wealth, prepare a large amount of nano active carbon spheres and be applied to environmental protection and lubricated and heat radiation additive agent field, can be used as a kind of method of algae-residue resource utilization, reducing the harm that algae-residue and algae toxin bring, also is the method that a kind of environment-friendly high-efficiency prepares nano material simultaneously.
