Description
Technical field
The invention belongs to marine environment investigation technical field, specifically, relating to one is bottom underwater water sample original-position collecting device and water sampling method in electric-controlled ball valve formula.
Background technology
Along with the exploitation of ocean, environmental pollution is also day by day serious.Wherein marine oils pollution problem attracts wide attention.Oil pollution ocean, brings huge harm to the marine eco-environment.Stand in the breach, account for the planktonic organism of the marine food chain lowermost layer of about whole ocean gross primary productivity 95%.The oil dissolved in the seawater is larger to fish harm.Its infringement various tissue of fish and organ.Oil to fish egg and larva harm obviously.Containing the oil of 0.1 milligram in one liter of seawater, hatching juvenile fish out will be caused to be all lopsided, and can only to survive 1 ~ 2 day.Live in the zoobenthos in seabed, as sea cucumber, various shellfish, starfish, sea urchin etc., extremely responsive to oil, even if only have the oil of minute quantity in living environment, activity and the breeding of shellfish also can be affected.Aquatic resources are caused to be destroyed.Oil pollution is generally all with just like benzopyrene, Benzanthracenes carcinogen.These materials are easy in sea life cylinder accumulation and enrichment, are difficult to decompose.The content being subject to carcinogen in polluted marine food is higher than non-marine food up to a hundred to several thousand times.The edible marine product polluted just likely will wait carcinogen to take in body, finally be detrimental to health.Biologic chain is polluted.For seabird, can enter into alimentary canal because of oil thus cause serious stimulation to stomach and intestine, intrahepatic fat is changed, adrenal gland expands, and makes seabird become apocleisis, slowly dies of hunger.Live in the extra large beast in oil pollution district, the sense of smell as whale, dolphin, sea lion, sea otter is very blunt, causes all injuries therefore brought.It is reported, immediate and mid-term is because of existing more than the 1000 kind of sea hydrobiont extinction of oil pollution, and sea life decrease 40%.Oil pollution worsens water body.
Enter the oil in marine environment, its natural degradation and microbial decomposition, dissolved oxygen DOs a large amount of in seawater can be consumed.In order to be oxidized 1 gram of oil, approximately need the oxygen of 3 ~ 4 milliliters.1 liter of oil is fully oxidized, the oxygen that will run out in 400,000 liters of seawater, is equivalent to area 1 square metre, the whole dissolved oxygen contents in dark 400 meter water columns.Seawater severe depletion of oxygen, brings disaster to all sea life, from planktonic organism to huge extra large beast.Oils can form the solid block of large stretch of pitchy simultaneously, destroys natural landscape.By in the alkali flat of oil pollution, toxic action is for many years sustainable, hinders biological cluster again.In decades recently, China coast aquatic resources fail, and move outside fishing ground, traditional economic fish amount of fishing obviously declines, and the oil pollution be subject to ocean has some relations.
On September 2nd, 2011, CNOOC's Peng Lai 19-3 oil field leakage of oil event, also Kang Fei leakage of oil event is claimed, serious pollution is caused to Bohai Sea ecologic environment, due to law and monitoring detection means not in place, cause event to delay effectively to be processed, in joint investigation process, the water sampling equipment of use and method are subject to the query of abroad expert.
The Sampling Survey of oleaginousness in different depth water body, for the diversity of analysis and research according to oil existence form in water body, nonunf ormity and oil are to the pollution condition of water body, gather the existing way of floating oil, dispersed oil, oil emulsion and dissolving wet goods various ways, understand the rule that oils shifts at water body, decomposes, spreads and change, oceanographic survey and scientific research are had great importance and acts on.
Gather the singularity that oils water sample has it, the material such as organic glass, rubber is easily stained by oil, can not be used for gathering oils water sample.
The original position water sampling of biological species research it is also proposed same request for utilization, namely keeps the clean state after sampling bottle sterilization, starts to gather water sample when arriving set depth, ensures that the water sample gathered represents the home state of collection point.
At present not used for bottom collector in collection original position water sample.Existingly generally use mechanical type original position hydrophore, utilization be mechanical principle, hydrophore is put under water, drops to set depth, and the buoyancy of ball float pulls open the lid of container, after water filled by container, rises to the water surface.Its shortcoming existed is:
1. the degree of depth can not reach requirement: the mode of prior art, is not suitable for the degree of depth of less than 10 meters, because under water under pressure effect, uncap needs larger power, and ball float and gravity are difficult to realize;
2. depth under water controls inaccurate: the length that depth under water controls to decline by hawser calculates, and need estimation by interference such as ocean currents in heeling condition, sampling depth position is inaccurate;
3. hawser is easily wound around, and water success ratio is adopted in impact: time the degree of depth is darker, under the effect of current, the hawser of ball float and hydrophore hawser are easily wound around, and impact normally works.
4. the lid adopted after water on bottle is poorly sealed: after sampling bottle is filled under water, gravity and buoyancy make lid not seal completely to close, water sample in uphill process in sampling bottle is easily subject to the interference of other water layer, water sample mixing can not reflect set depth water quality condition truly, the result utilizing such water sample to draw and actual result have certain difference, are thus subject to the query of expert.
Visible, existing machinery formula hydrophore technology is being adopted in water process, realizes adopting water by lid switch, can cause and close the not tight seepy question of lid, make water sample untrue thus.Due to above deficiency, bottom water sample in cannot gathering, the inefficiency when top layer water sampling, the water sample impact of collection is normal to be used and test result.
Existing deep-casting device, its principle puts under water with tubular container, after arriving set depth, the upper and lower side of tubular container sealed, collects the water sample of set depth.But this mode contacts the water sample of different levels in tubular container decentralization process, interference is produced to the water sample state of set depth, the requirement of in-situ acquisition can not be met, be not suitable for oils and biological species water sampling.
Summary of the invention
The invention provides a kind of underwater water sample original-position collecting device and water sampling method, it can solve the problems referred to above that prior art exists, and meet the needs of middle bottom water sample in-situ acquisition, solve the deficiency of the degree of depth of the in-situ acquisition under water aspect existence that prior art exists, the original position water sample of the degree of depth within gathering 100 meters.
