Description
Technical field
The utility model relates to Ecology detection technique fields more particularly to a kind of planktonic organism sample rapid concentration to fill
It sets.
Background technique
It is not only most important primary producer in aquatic ecosystem in phytoplankton, and is the master of oxygen in water
Supplier is wanted, it starts the food web in aquatic ecosystem, recycles and believes in energy flow, the substance of aquatic ecosystem
It is played a crucial role in breath transmitting.Type composition, structure of community and the Plantago fengdouensis of phytoplankton, directly affect water body
Water quality, system self-energy stream, material stream and living resources change.
Phytoplankton is the instruction biology for measuring water quality, and one of direct result of water pollution is phytoplankton species
The variation of composition.A piece of water area water-quality is how, has inseparable relationship with the abundant degree of phytoplankton and group's composition,
In unpolluted water body, the group origin cause of formation season of algal kind and the variation of environmental factor and change, but this change
Change in a specific water body, be regular in ordinary circumstance, and is then with pollutant and dirt in contaminated water body
The variation of the different population composition of dye degree is irregular.The reduction of phytoplankton or excessive multiplication will indicate that piece water
Domain just tends to deteriorate.Especially those are more sensitive to environmental change, like low temperature, the content of organic matter is low, the big gold of water transparency
Algae changes most obvious in polluted-water.Such as the increase of lake (reservoir) phytoplankton quantity, especially cyanobacteria overgrowing and life
The extension of long season is exactly an important symbol of lake (reservoir) eutrophication.
Acquisition phytoplankton sample simultaneously studies its population composition and structure of community as prevention and treatment eutrophication water, monitoring water
One of the important means of environmental protection measures such as matter health.Phytoplankton sample after acquisition is needed could be after by concentration pretreatment
It is detected under continuous microscope, therefore phytoplankton concentration pretreatment becomes the necessary program of microscopy algae bio type and composition.This
Outside, zooplankter is economy aquatic animals, is the important bait of waters Mesichthyes and other economic animals at the middle and upper levels, to fishery
Development is of great significance, and microzooplankton water sample is equally also required to carry out concentration pretreatment.Currently, concentration pretreatment is common
Method be to transport water sample to laboratory, the water sample of acquisition is placed in 1000ml cylinder settling vessel (logical common plastics
Bottle replacement) in staticly settle 48 hours, then the supernatant that phytoplankton is free of in water sample is extracted out using siphon pipe, it is remaining
The sediment of 30-50ml pours into sample bottle, then cleans precipitating wall with above-mentioned supernatant, and cleaning solution is poured into volumetric bottle
In, then 48 hours precipitatings are carried out, realize constant volume.Siphonic process is cumbersome, and insertion sample one end will keep absolute rest, avoids disturbing
Dynamic water layer, concentrating sample volume are difficult to control, and are easy to also take phytoplankton away when extraction clear liquid, and sample damages
It loses, influences sample quality.And this method needs are precipitated for a long time, and sample processing time is too long, inefficiency.It should
If acquisition of the method for field bulk sample is concentrated, freight volume is big, and efficiency is lower.Patent document CN206223518U is disclosed
Phytoplankton sample concentration device based on vacuum pump and filter membrane, saves the time of precipitating, but the problem of these devices
It is: after having aspirated liquid, needs to remove filter membrane and be put into sample bottle, it is complicated for operation, and be easy when shifting filter membrane
Pollution is introduced, in addition, the algae on filter membrane is difficult to dissolve, furthermore liquid needs to shift, and can not be directly realized by constant volume, operation sequence
Complexity, it is inconvenient for use.It is readily transported therefore, it is necessary to designing one kind, reduces sample processing time, improve accuracy, is easy to operate
Phytoplankton sample concentration device.
