Abstract
The invention discloses an offshore eutrophic sea area nutrient-substance extinction device, which comprises a porous digestion tube, wherein suspended biological filling materials are arranged inside the porous digestion tube. Through the porous digestion tube which is filled with the suspended biological filling materials, when a cage culture sea area is established, micro-organism colony in substrate sludge of the corresponding sea area is only attached onto the suspended biological filling materials after being propagated, and then the offshore eutrophic sea area nutrient-substance extinction device is installed on the bottom part of a cage, so particles such as residual baits, fecal matters and the like produced in the culture process can fall down and can be used as carbon sources of micro-organisms, the micro-organism colony can continuously degrade nutrient substances in the water, and the function on effectively reducing eutrophic substances in the water such as suspended particles, nutritional salt and the like can be realized. The offshore eutrophic sea area nutrient-substance extinction device has a simple and reliable structure, and can be widely used for the extinction of the nutrient substances in the offshore eutrophic sea area.
Description
Technical field
The present invention relates to used assistive device in a kind of aquaculture, particularly used nutriment abatement device in the cage culture of offshore sea waters.
Background technology
The seawater cage culture system is artificial person worker's breeding ecological system of a kind of high density, high bait throwing in.Coastal waters aquaculture developments such as cage culture in recent years are rapid, and the sewage discharge that is produced in breeding process and the people's productive life will cause the waters in the ocean, and particularly the water nutrition problem of offshore sea waters is more and more serious.Cage culture is through setting up net cage, it is immersed in the seawater, form a semi-enclosed culture zone, in this zone, can raising marine products such as fish.But cage culture has not only accumulated the residual bait ight soil of a large amount of fish in the bottom, culture zone, causes the substrate anoxic, influences the benthon bacterium colony and changes, and also can cause local marine site nutrient laden owing to a large amount of nitrogen phosphorus that the fish excreta discharges.At present to the water body improvement method in eutrophication marine site, this coastal waters, just the method for raising together with through plantation tangleweed, shellfish is subdued, consumption power a little less than, and do not have a kind of effectively, solve this problem to the abatement device of cage culture.
Summary of the invention
The object of the invention is for eutrophication marine site, a kind of coastal waters nutriment abatement device is provided.
The solution that the present invention solves its technical problem is:
Eutrophication marine site, a kind of coastal waters nutriment abatement device, it comprises the porous canalis alimentarius, is provided with suspended biological filler in the said porous canalis alimentarius.
As the further improvement of technique scheme, be provided with several suspension balls in the said porous canalis alimentarius, be filled with described suspended biological filler in the said suspension ball.
As the further improvement of technique scheme, also be provided with the lifting arm on the said porous canalis alimentarius.
The invention has the beneficial effects as follows: the present invention is built-in with the porous digest tube of suspended biological filler by setting; Make when building the cage culture sea area; It is attached in the said suspended biological filler only to need that the microbe colony in the bed mud of corresponding sea area is expanded numerous relief; Then the present invention is installed in the net cage bottom; Particles such as the residual bait ight soil that in breeding process, is produced like this can fall and as the carbon source of microorganism; Nutriment and microbe colony can constantly be degraded in the water body; Complement each other, thereby realize subduing the function that suspended particulate substance, nutritive salt etc. make the material of body eutrophication effectively.The present invention is simple and reliable for structure, can be widely used in the nutriment of subduing eutrophication marine site, coastal waters.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing and embodiment.
Fig. 1 is a structural representation of the present invention.
Embodiment
With reference to Fig. 1, eutrophication marine site, a kind of coastal waters nutriment abatement device, it comprises porous canalis alimentarius 1, is provided with suspended biological filler in the said porous canalis alimentarius 1.Suspended biological filler is a kind of in the biologic packing material, has the advantages that specific surface area is held trickle material greatly, easily.In use, to the situation in different sea areas, the microorganism of extracting in its bed mud is expanded numerous being placed in the suspended biological filler, cultivates into fixing microbe colony, has promptly built the environment of a microbial degradation water nutrition material.
Further, be provided with several suspension balls 2 in the said porous canalis alimentarius 1, be filled with described suspended biological filler in the said suspension ball 2 as preferred embodiment.Said suspension ball 2 is ball floats used in the conventional aquaculture; Its dimidiation ball and inside have spatial accommodation; The suspended biological filler that contains microbe colony is filled in this space; Close suspension ball 2 then; Promptly be made into the finished product of a suspension ball 2, then a plurality of said finished products put into porous canalis alimentarius 1 and get final product.Certainly, the aperture, digestion hole of porous canalis alimentarius 1 should be less than the sphere diameter of suspension ball 2, and the ball 2 that prevents to suspend floats.In fact said suspension ball 2 has provided a container that tentatively holds suspended biological filler, and the parts that can adopt in addition similarly, can comprise suspended biological filler according to reality replace.
Further, also be provided with lifting arm 3 on the said porous canalis alimentarius 1 as preferred embodiment.Said lifting arm 3 can be convenient to the present invention is lifted on the bottom of net cage.Certainly, in the actual production, the present invention can a plurality ofly be provided with in groups.
Compared with prior art, the present invention has the following advantages:
1, the present invention can subdue particles such as the residual bait that produces in nutriment and the breeding process in the water body, ight soil on the spot; Realize the harmless processing of eutrophication material; To improving cage culture district substrate and water body environment quality, it is significant to improve the marine site carrying capacity.
2, the present invention is economical and practical, and is easy for installation, instant effect, long service life.
More than be that better embodiment of the present invention is specified; But the invention is not limited to said embodiment; Those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite of spirit of the present invention, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
