Abstract
The invention provides a method to collect the blue algae water bloom. The invention comprises a bottomless closed floating rail, the blue algae water bloom floating on the water surface is extracted into the floating rail by an air lift and a movable suction pipe matched with the air lift, thus the blue algae water bloom is enriched in the floating rail. The suction pipe adopts a wide-mouth surface suction opening. The floating rail is a bottomless closed floating rail with the depth of 50-250 cm. The invention has high efficiency, strong practicability, the composing device is simple in structure, low in price and can collect the blue algae water bloom in large scale and has high efficiency, which can be widely suitable for the collection of blue algae water bloom in the lake or reservoir. The surface suction opening is arranged on a floating body or a ship that is outside the floating rail, especially on a floating type air lift system.
Description
One, technical field
The present invention relates to collect the method and apparatus of water surface floating body, especially collect the method and apparatus of the wawter bloom of algae such as blue-green algae.
Two, background technology
The wawter bloom of algae such as blue-green algae is a kind of water surface floating body, also is the major reason that causes China's rivers and lakes water pollution in recent years repeatedly.Blue-green alga bloom accumulates in intake at the following wind direction of lake and causes great influence to living water use.The improvement of blue-green algae has multiple scheme, and the work appearance of effecting a permanent cure is carried out gradually.But the work that takes stopgap measures is also very important.Relate to a kind of Algae absorbing device of collecting blue-green alga bloom as CN200410012732.9, utilize ladder shape floating tube that the bloom blue algae of water surface enrichment is absorbed collection by pump.This Algae absorbing device is made up of dovetail groove assembly, support, cover plate, hinge and water pump pipe, the dovetail groove assembly is housed in dovetail groove, dovetail groove assembly, floating drum, lifting pump barrel, adjuster, two-layer filter screen fence are by support, cover plate attaching nut and bolt, at the dovetail groove front end adjuster is set, fix with traveling nut and movable bolt with a thin plate two, fix a slot on the dovetail groove both sides, in the two-layer filter screen fence insertion groove.Main method and the device that filters that utilize.
CN200410012928.8 method of controlling blue-green alga bloom is mentioned machinery except that algae, and fixed blue-green alga bloom scavenge unit and portable blue-green alga bloom scavenge unit are arranged.
But prior art fails to be applied to the removal blue-green algae of large-area water body, comprises that the efficient of removal is also very important, and these all are to need the problem that solves in the practicality.
Three, summary of the invention
The present invention seeks to: propose a kind of method and apparatus that can efficiently collect blue-green alga bloom, especially the large tracts of land water surface and a large amount of in water body, collecting or the enrichment blue-green alga bloom, have only large tracts of land and a large amount of the collection or the enrichment blue-green algae, this be carry out handle or even the processing of practicality in most crucial steps.
Technical scheme of the present invention is: the method for collecting blue-green alga bloom, the sealing at the no end is floated to enclose and is blocked, carry and carry supporting movably suction water pipe with gas with gas, suction water pipe especially has wide mouthful of superficial water water sucking mouth and draws the blue-green alga bloom that accumulates in the water meter surface layer, the sealing that sucks the no end float enclose block in, enrichment blue-green alga bloom in the unsteady fence of the sealing at the no end.
The present invention adopts unsteady the enclosing of sealing all around at a no end to block.Floating, to enclose the degree of depth of blocking be 50-250 centimetre.
Movably wide mouthful of superficial water water sucking mouth is a soft aqueduct.The sectional area of water sucking mouth can be from the 30-2100 square centimeter.
The present invention imports blue-green alga bloom does not have unsteady the enclosing at the end to block.Float enclose block in to block inner area big because enclose, and can think that in vertical direction water flow velocity goes to zero.Blue-green alga bloom is because self buoyancy function is floating to the water surface, and unnecessary water flows back to water bodys such as lake from enclosing the side of stopping.Blue-green alga bloom be left on enclose block in, and then reach the purpose of collecting blue-green alga bloom.Carry the stripping tube of the power employing blower fan drive of blue-green alga bloom, with the disturbance of minimizing to blue-green alga bloom, and the efficient height, energy consumption is low, is convenient to water bloom floatation of blue algae.
Floating, it is unqualified to enclose the area that blocks, and general range also can be bigger tens to hundreds of square metre, for example adopts the air-lift device of the blower fan of power of motor 3kW can handle the blue-green alga bloom of thousands of square metres the water surface in one hour.
Collect the device of blue-green alga bloom, the unsteady water-supply-pipe that blocks with air-lift device that encloses of sealing that comprises the no end constitutes, float to enclose to block and comprise enclosing and block floating body and fence body, the formation of floating body is the even point-like thing (the floating strong point) that circle is lived the fence shape, directly connect with fabric fence body between the adjacent floating body, two root polypropylene semihard pipes are strengthened, and the fabric lower end is provided with weight and hangs.More specifically device is seen embodiment.
Carry and carry movably wide mouthful of supporting superficial water water sucking mouth with gas and draw the blue-green alga bloom that accumulates in the water meter surface layer with gas, suck sealing unsteady enclose block in, movably wide mouthful of superficial water water sucking mouth connects soft aqueduct generally moves about by adhering to a buoyancy aid or ship, is used for large-area removing wawter bloom.
The efficient height of the inventive method, practical, apparatus structure is simple, and price is low, and collection blue-green alga bloom scale is big, efficient is high, is widely used in the collection of lake, reservior blue-green alga bloom.The superficial water water sucking mouth is mounted in to float to enclose and blocks on the outer buoyancy aid or ship, especially constitutes floating type gas and puies forward system.
