Abstract
The utility model provides a plankton rapid concentrating device which is provided with a cylindrical filtering device made of a filter net, wherein the top of the cylindrical filtering device is provided with an opening end, the cylindrical filtering device is made of a filter net all around, diameters of meshes of the filter net ranges from 5mu m to 10mu m. When 1L of plankton-containing ballast water in volume is concentrated, a general natural settling and concentrating method adopted during concentration in the prior art is a gradual concentrating method, and at least one day is consumed, but the plankton rapid concentrating device has the advantages of shortening the concentration time greatly, and being capable of completing concentration within 1h, thus a water sample can be rapidly detected after the sampling is ended.
Description
Technical field
The utility model relates to the quick enrichment facility of planktonic organism, and particularly, the utility model relates to and is not less than the planktonic quick enrichment facility of 10 μ m.
Background technology
Ballast Water is meant water and the suspension thereof that installs additional for control boats and ships trim, heel, drinking water, stability or stress aboard ship.Boats and ships for vacating tonnage, must be drained into Ballast Water in the marine site of bank state during to bank.Show that according to related data the Ballast Water that global boats and ships carry every year has 12,000,000,000 tons approximately, contains a large amount of biologies and microorganism in the sediment of Ballast Water and ballast tank, has comprised bacterium, algae, protozoan, planktonic organism and other biological.The animal plankton that average every cubic metre of Ballast Water contains is above 100,000,000; The whole world is present in is diffused into all over the world with boats and ships in the ballast water for ship that the sea life in marine site have 7000 kinds approximately every day; Many bacteriums, animal and plant still survive in Ballast Water and the sediment thereof through the voyage of several months; When boats and ships when freight in the harbour, these biologies are along with Ballast Water is discharged into harbour state waters.The biology of ballast water for ship discharging may be preyed on local species; Change living environment or change environmental baseline (as reducing the transparency of water); Replace local species, reduce local bio-diversity, even cause the extinction of local species, the destruction of whole ecological system etc.; The species of ballast water for ship discharging also possibly cause direct economic losses such as reducing marine product output, cause the indirect economic loss relevant with the human health ecology influence; The microorganism of ballast water for ship discharging shifts and may form fearful threat; Ballast Water is except carrying bacterium and virus; Also can transmit some microalgaes; Comprise the poisonous kind that possibly form harmful water bloom or red tide, these pathogen and microorganism possibly cause human serious disease even death.
Therefore along with the fast development of international trade and navigation forwarding business; Ballast Water loading and discharging internationally is on the increase, and ballast water for ship carries problems such as health that adventive and pathogen cause, environmental protection, marine ecology and more and more receives the concern of international organization and countries in the world.According to " ballast water for ship and sediment control and management international convention (draft) ", D-2 bar Ballast Water operative norm.Just allow to discharge after differentiating the standard that reaches through the survival in the Ballast Water is biological according to these discharging needs that carry out the ballast water for ship of Ballast Management, this just need detect the Ballast Water of the ship that reaches port fast.But under existing detection technique condition, the fast detecting planktonic organism is a very big challenge.
Ballast Water 10～50 μ m planktonic organism live bodies identify present stage be the maximum rate-limiting factor during Ballast Water detects, and therefore traditional natural subsidence method length consuming time also be key one ring that detects ballast water for ship.
On 10～50 μ m planktonic organism live body discrimination methods, the domestic standard method of operating efficiently that lacks especially is in this respect research work has caused certain degree of difficulty.
Therefore need the quick enrichment facility of a kind of simple, fast planktonic organism.
The utility model content
The purpose of the utility model is to overcome prior art when detecting the planktonic organism live body, and common length consuming time of institute's method of application and drawback such as loaded down with trivial details provide a kind of simple, fast planktonic organism quick enrichment facility.
The technical matters of the required solution of the utility model, can realize through following technical scheme:
The quick enrichment facility of planktonic organism, it has the cylindrical filter of being processed by filter screen, and the top of said cylindrical filter is an openend, and the whole body is all processed by filter screen, and the mesh diameter of said filter screen is 5 to 10 μ m.
Preferably, the mesh diameter of said filter screen is 10 μ m.
In an embodiment of the utility model, the top of said cylindrical filter is provided with fixed support.
In an embodiment of the utility model, said support bracket fastened quantity is more than 2.
The beneficial effect of the utility model is; Concentrate same 1L volume contain the planktonic organism Ballast Water time; Prior art adopts general natural subsidence method for concentration to be method for concentration step by step when concentrating, and at least 1 day consuming time, and the quick enrichment facility of the planktonic organism of the utility model has shortened concentration time to a great extent; Only need 1 hour consuming time, therefore after sampling finishes, can detect water sample fast.
Description of drawings
Fig. 1 is the synoptic diagram of the quick enrichment facility of planktonic organism of an embodiment of the utility model.
Fig. 2 is the user mode figure of the quick enrichment facility of planktonic organism of the utility model.
Embodiment
For the technological means, the creation characteristic that make the utility model, reach purpose and effect and be easy to understand and understand, below in conjunction with accompanying drawing and specific embodiment, further set forth the utility model.
Embodiment 1
Referring to Fig. 1,2, the quick enrichment facility 10 of the planktonic organism of the utility model, it has the cylindrical filter of being processed by filter screen 11, and the top of said cylindrical filter 11 is an openend 12, the blind end 13 of bottom for being processed by filter screen.
The mesh diameter of said filter screen is 10 μ m.
