Description
Technical field
The present invention relates to water body cleaning technique field, especially a kind of device and using method thereof removing blue-green algae in water body.
Background technology
Along with the develop rapidly of economy, the dependence of the mankind to water resources is also more and more heavier, but water bodies management be not good at life-time service chemical fertilizer etc. easily loss rich nutritive material result in the nutrient laden of water in lake, body eutrophication is the great environmental problem that current countries in the world face, the outstanding problem that water nutrition brings is breaking out of blue-green alga bloom, what large-scale blue-green alga bloom reduced water resources utilizes usefulness, cause serious ecological damage and huge financial loss, and the generation of cyanophycean toxin brings very big hidden danger to public security health.
Blue-green algae is a class and ancient, small prokaryotic organism thereof, and long-term evolution defines extremely strong ecologic competition advantage, can obtain maximum growth rate under appropriate circumstances, and increases rapidly with exponential.Research finds, blue-green algae has the ecological growth regulin of self reinforcement machining function, and it can be made to produce offspring as much as possible, thus toxigenic bacterium strain density is increased, obtains competitive edge, the few and blue-green alga bloom that quantity is large of formation kind.Particularly some inland lakes, every summer high temperature weather, blue-green algae will present the trend of large-scale outbreak, wherein, the wawter bloom of more than 80% produces Microcystin, more has the blue-green algae of 50% ~ 70% can produce multiple toxin, comprise the biological peptide of liver injury, neurotoxin alkaloid etc., organism toxicosis directly can being caused when these cyanophycean toxin amounts are many dead, also enter human body because of gathering effect by tap water and edible aquatic products when amount is few, the existence of harm humans is healthy.
Breaking out of Taihu Lake blue-green algae in 2007 is the concentrated reflection that blue-green algae pollutes, and causes the life water of productive use supply of the multiple counties and cities of periphery to paralyse, and this is not an example, and the inland lake peripheries such as Dian Chi, Chaohu, Erhai all have the event of cutting off the water on a large scale because blue-green algae pollutes.Further, breaking out of blue-green algae is not limited to large waters, is also to concentrate to break out district in breeding fishing ground and lake, and these coverages of water are little and shallow, and large-scale mechanical filter formula is removed algae mode and be can't bear to reuse, even if be put to use also, cost is higher.Therefore, research one can take into account different waters except algae problem, and the device realizing the improvement of high efficiency, low cost oligosaprobic blue-green algae is very necessary.
The Chinese patent of application notification number CN101708881A, disclose a kind of permanent magnetic separation purification device for lake eutrophication alga water, this device to use in magnetic flocculant Coagulation and Adsorption lake eutrophication water body the materials such as blue-green algae to form magnetic flco, through permanent magnetic separation purification device, by disk quick adsorption in water, rotate continuously with disk and shift out the water surface, removed by the algae device of scraping of the water surface, blue-green algae flocs unit is wriggled through auger and is sent into storage algae storehouse press filtration, realizes algae/water and is separated.Although this invention can realize the efficient removal of blue-green algae, this device complex disposal process, if will cause damage to device containing solid impurity in Complex water body, the use of complete assembly will be by a large amount of consume electric power, and cost is higher.
The Chinese patent of application publication number CN104365670A discloses a kind of except blue-green algae preparation, is prepared from by copper sulfate, Tai-Ace S 150, iron(ic) chloride, calcium carbonate and magnesiumcarbonate.Said preparation uses chemical algae removing method, and to the Scavenging activity efficiently simple low cost of blue-green algae, but the metamorphosis of bivalent cupric ion to the biological young has teratogenecity, and causes the severe detachment of feed algae; Meanwhile, copper sulfate has toxicity, can destroy the normal ecosystem of water body, and said preparation is to human body and naturally harm is very important.
The harm of blue-green algae is obvious to all, but conventional physical filters the high cost of Refloatation method, and the secondary harm of traditional chemical method for killing is all a unavoidable difficult problem, and therefore, invent a kind of low cost, high-level efficiency, the algae-removing device of non-secondary pollution is very necessary.
Summary of the invention
