Description
Technical field
The invention belongs to field of environment protection, specifically is method and algicide that a kind of flocculation magnetic polymer is administered algal tufa.
Background technology
In recent years, the generation of the rivers,lakes and seas wawter bloom of China, development have caused the extensive concern of various circles of society, large-area algal bloom, havoc the balance and stability of aquatic ecosystem, not only influenced water landscape, influenced the development of culture fishery, and algae toxicity has constituted the threat to environment for human survival.Only red tide reaches more than billions of units for the coastal financial loss that causes every year, so breaking out of algae becomes a kind of disaster.Cause that main nutrient elements that algal tufa breaks out is that nitrogen, phosphorus, particularly phosphorus in the water body plays critical effect.Remove the algal bloom method than popular at present and roughly can be summed up as physics method, chemical method and biological process.
Physics method physical method is (as high pressure ionization, high-voltage pulse, alternating intense magnetic field, ultraviolet ray, ultrasonic wave etc.) then be to be converted into chemical energy with electric energy, change molecular structure and the character enter water body or water body material, reach and kill and wound, kill impurity in algae and decomposition, the adsorbed water body, reach the purpose that purifies water system.This advantage is not destroyed water body, noresidue, but physics to kill and wound be relation of equal quantity, it is big more to kill and wound life entity, consumption is many more, it is many more to kill and wound many more energy consumptions, water quality impurity is many more, it is many more to consume energy.The method that comprises mechanical process in addition or manually salvage algae and take to dredge, the former can only can not tackle the problem at its root as easy supplementary means, and expends a large amount of manpower and materials, has little effect.
Chemical method mainly is to adopt various chemical algae removing agent, its most pronounced effects, but also have most danger, thus very prudent when using, in strict accordance with the consumption operation that requires, otherwise can cause serious consequence.Because the chemical ingredients of these algicide is the copper compound of processable, perhaps chelated copper class material, these compounds produce injury to a certain degree even cause death the Shui nationality such as fish pasture and water are biological, and carcinogenesis is arranged, and also can produce other some uncertain bad sequela.
Biological process biological restoration algicide is at tens kinds of living microorganisms and the corresponding enzyme of handling eutrophication water, it is a kind of pure biotechnological formulation of All Pure Nature, the hydrobiont in the water body and the mankind etc. are not produced any harm and side effect, in a single day product drops into water body, the algae competition nutrition source in rapid activation of the microorganism in the product and the water, thus make algae lack nutrition death, sink under water, increasing microorganism continues the dead algae of degraded, until elimination, makes water body become clear.But biological process particularly the method for restoration of the ecosystem among a small circle, the control of algal tufa is an important method in the FX. but these class methods often need to drop in advance huge artificial engineering, to create and control suppresses the condition of required waterplant of algal tufa (bottom low in transparency as submerged plant or that lack suitable bed mud is difficult to existence) or animal survival, thereby take effect slow, cost is high, the difficult improvement that generally is applicable to big area, sudden algal tufa.
Above several method, though can play the effect of alleviation to a certain extent to wawter bloom, they have, and a common shortcoming---phosphor-removing effect is not obvious, can not solve the key issue that algal tufa breaks out, and cures the symptoms, not the disease.
Once invented a kind of algae-removing method quick and with low cost of collecting at this problem application, this technology is the adsorption-flocculation algae effectively, simultaneously can rapidly algae be shifted out water body by the effect of foreign field again, and to nitrogen, phosphorus removal effect highly significant in the water body, can accomplish to treat both principal and secondary aspect of disease, but this method flocculation is quick inadequately, and the flco of formation is closely knit inadequately, is unfavorable for that follow-up magnetic mask work carries out.
Summary of the invention
The applicant has proposed a kind of method and algicide of new treating algae bloom by strong-flocculation magnetic polymer on the basis of original research work, this method not only cost is low, and has strong flocculence and fast-response, satisfies the time needs of magnetic mask work.
Technical scheme of the present invention is as follows:
The method for the treatment of algae bloom by strong-flocculation magnetic polymer, it is characterized in that it being the strong flocculence of utilizing aluminium iron polychloride, aluminium iron polychloride and ultrapure magnetic iron powder are mixed into the strong flocculation agent suspension liquid of magnetic, put in the water body environment that is rich in algae and nitrogen, phosphorus, rapid flocculation frustule and adsorption of nitrogen, phosphorus, and form the closely knit flco of bulk, utilize the magnetic responsiveness of ultrapure magnetite powder, enrichment frustule apace under the effect of outside magnetic field transports the water body zone.
The method of described treating algae bloom by strong-flocculation magnetic polymer is characterized in that by aluminium iron polychloride: the mixed of ultrapure magnetite powder: water=1-3g:0.5-1.5g:4-6ml evenly makes the strong flocculation agent suspension liquid of magnetic; Ratio in 50-200mg/L joins the strong flocculation agent suspension liquid of magnetic in the water body environment, and stirs.
The method of described treating algae bloom by strong-flocculation magnetic polymer is characterized in that by aluminium iron polychloride: the mixed of ultrapure magnetite powder: water=2g:1g:5ml evenly makes the strong flocculation agent suspension liquid of magnetic; Ratio in 70-200mg/L joins the strong flocculation agent suspension liquid of magnetic in the water body environment, stirs between 20 seconds in second to 50.
The algicide for the treatment of algae bloom by strong-flocculation magnetic polymer is characterized in that it being the aqueous suspension that contains aluminium iron polychloride and ultrapure magnetite powder.
The algicide of described treating algae bloom by strong-flocculation magnetic polymer is characterized in that wherein the proportioning of each component is aluminium iron polychloride: ultrapure magnetite powder: water=1-3g:0.5-1.5g:4-6ml.
The principle of the invention is: Yi Bian utilize the strong flocculence rapid flocculation frustule of aluminium iron polychloride and adsorption of nitrogen, phosphorus, and the closely knit flco of formation bulk, utilize the magnetic responsiveness of ultrapure magnetite powder on one side, enrichment frustule apace under the effect of outside magnetic field, transport the lake region, alleviate the pressure that the lake algal tufa causes to a certain extent.The material therefor aluminium iron polychloride is the strong flocculation material of a kind of cheapness, and scale operation easily, stable performance are easy to reclaim; Ultrapure magnetite powder source is wide, cost is low and environmental friendliness.
Advantage of the present invention:
The frustule clearance reach more than 99%, total nitrogen reduce about 85%, total phosphorus reduces more than 93%, COD reduces about 95%, turbidity and reduces more than 96%.
The flocculation of this method fast and flco closely knit, satisfy the needs of magnetic mask work.Simultaneously, the magnetic flocculant stable performance can repeat to recycle.
3. the performance magnetic breeze and the synergy of flocculation agent by force, existing strong flocculence has strong magnetic responsiveness again, makes that objectionable impuritiess such as algal tufa, nitrogen, phosphorus, COD are shifted out under the action of a magnetic field fast, has stopped secondary pollution.
