Description
Technical field
The present invention relates to testing equipment field, in particular to a kind of suspended particulate substance sampling apparatus and its method of samplings.
Background technique
Suspended particulate substance, refer to particle diameter at 0.45 μm or more, the particulate matter being present in water body with suspended state.Water body
Middle suspended particulate substance is that there are media for important in the water body of various pollutants, mainly includes suspension bed sediment, plant of swimming
Object, zooplankter, detritus (organic broken) etc. play migration, distribution of the various pollutants in aquatic ecosystem important
Effect, bioavailability and final home to return to pollutant have important influence, with to suspended particulate in water body
Object research is goed deep into, and the method for suspended particulate substance sample acquisition becomes the basis of accurate, quick research suspended particulate substance.At present
It is field condition acquisition water sample that suspended particulate substance, which samples most common method, in water body, then uses funneling filter device pair
Water sample is filtered, and acquires suspended particulate substance sample.
Affected by environment, the suspended particulate substance diameter in different waters is different, when being relatively large in diameter in suspended particulate substance
When the aperture of strainer is smaller in funneling filter device, it will lead to strainer and be blocked and suspended matter can not be filtered out, generally use
Method be agitation acquisition water sample, however which will lead to and collide between suspended matter, influence the true of subsequent detection
Property.
Summary of the invention
Based on problem above, the present invention provides a kind of suspended particulate substances to use device and its method of sampling.The present invention can
Realize prevent because in water sample suspended particulate substance be relatively large in diameter due to block the purpose of strainer, filtered by being connected in outlet pipe internal screw thread
