Description
Technical field
The utility model relates to a kind of biological filter screen sampler for ship ballast water management system biological detection.
Background technology
Foreign-going ship, when injecting and discharge ballast water, easily causes the territory over strait of unwanted aquatic organism and pathogen to propagate.Ballast water without control discharge, serious harm is caused to marine ecology, public health.The standard-required of D-2 article regulation that the discharge that Ballast Management system uses active substance to inject boats and ships and ballast water is effectively killed, made to the germ, microorganism etc. of ballast water of discharge meets " Management of Ships ' Ballast Water and sediment monitoring and management contract ", discharges the marine biological invasion that causes and the destruction to the marine eco-environment effectively to control ballast water for ship.
With regard to IMO " Management of Ships ' Ballast Water and sediment monitoring and management contract ", final Ballast Management target must carry out after process reaches D-2 standard, just allowing discharge to the ballast water be attached on ship.The Main Means of current this target of enforcement installs by boats and ships the ballast water treatment system (BWMS) obtaining model approval, carries out process meet ballast water.
Discharge of ballast water performance standard (D-2 standard) associated biomolecule index
| Survival aquatic organism | Quantity | Target microorganism | Safe level |
| ≥50μm | <10/m 3 | Poisonous comma bacillus | < 1cfu/100ml or < 1 cfu/g animal plankton sample |
| ≥10μm and <50 μm | <10/ml | Escherichia coli | <250 cfu/100ml |
| Enterococcus | <100 cfu/100ml |
D-2 standard whether is met in order to check the ballast water through Ballast Management system, need to carry out acquisition testing to ballast water sample, therefore need a set of can the easy sampling filter net device fast Biological indicators all in compressive effect and hydration index gathered.
The existing biological filter screen sampler for ship ballast water management system biological detection, generally be divided into 10-50 μm according to the diameter of mesh bag silk mesh, and more than 50 μm two kinds of specifications, structure is mesh bag and makes on stainless circular frame, circular frame is welded with metal straight rod handle, the cylindrical bottom portion being sewed with plastic material bottom mesh bag can the receiving flask of folding, in its use procedure, has obviously shortcoming.1, efficiency is low, image data does not possess synchronism, after the sample gathering complete certain volume, filter screen is rinsed well after moving into sample bottle by the sample needing people to be collected by the plastic collection bottle of bottom, carrying out second time sampling, middle about about 20 minutes of the used time, inefficiency, needs at least two people's cooperations.2, device is simple, cannot read data on flows, the critical datas such as hydration index; General biological filter screen is in gatherer process, the plankton in the seawater of comparatively accurate certain volume should be gathered, usual gatherer process, need the other personnel except collector, to read the start and stop illustrating sample collector to sample according to the electromagnetic flowmeter near apparatus for treating ship ballast water thief hatch, so not only inefficiency, and there is comparatively big error in flow, for inspection afterwards brings very big error.And in sampling process, the aquation parameter of institute's water sampling can not be read simultaneously, water sample must be gathered via other sample tap, then measure through Portable, multiple parameter water quality instrument, reduce efficiency, the synchronism of data cannot be realized again.3, cannot the perception depth of water, can only feel with sample collector the water sample gathering different depth.4, the biological species of more than 10-50 μm and 50 μm different sizes cannot be gathered simultaneously.5, cannot estimate the biomass of institute's sample thief, laboratory need be taken back and analyze.
