Description
Technical field
The utility model relates to a kind of environmental pollution monitoring equipment, in particular to micro- plastics in a kind of waters of rivers,lakes and seas
The monitoring sampling apparatus of pollution.
Background technique
Micro- plastics (Microplastics) refer to that diameter is not more than the plastic particles of 5mm, it has also become international extensive concern
One of hot issue.2014, it is urgently to be resolved that micro- plastic pollution is included in the whole world for the first time by first united nations environment conference (UNEP1)
One of ten overall situation problems.2015, the micro- plastics in ocean were included in environment and the second largest section of ecological science research field by UNEP2
Knowledge topic, and with Global climate change, ozone depletion and Ocean acidification become that global scientist pays close attention to jointly side by side it is great complete
Ball environmental problem.
Micro- plastics in water body are mainly derived from the mankind and use causes micro- plastics to enter environment containing micro- plastic grain product
With bulk plastic garbage decomposition or be broken into molecule and enter environment.Wherein, the plastic microbead added in personal care articles
(Microbeads) be exactly the micro- plastics of water body one of environment direct sources.Some personal cleaning articles for example bath oil, facial cleanser,
Toothpaste and some cosmetics such as eye shadow, mascara in moisturiser personal care articles, artificially add in production process with poly- second
Plastic microbead based on alkene and polypropylene material.After individual washes one's face and rinses one's mouth, plastic microbead enters sewage plant by sewer in waste water.By
It is small in size in plastic microbead, density is light, quantity is more, be difficult to effectively remove these plastics with current sewage plant conventional treatment process micro-
Pearl, and most plastic microbeads can enter natural water, it is final to import ocean and exist for a long time, and then by food chain to light
Water and marine ecosystems even human health cause potential hazard.Bulk plastic rubbish can also generate largely in degradation process
Plastic particles, these plastic particles are entered in rivers,lakes and seas waters by rubbish, soil and surface water cycle approach, are caused micro-
Plastic pollution.
Due to said circumstances, need to study micro- plastics form, the concentration etc. in water body, it is necessary to which we are according to need
It wants, acquires micro- plastic sample in water body, and detect the content of micro- plastics, ecological environmental protection and micro- plastic pollution for water body

Plastic grain calculates the content of micro- plastics in water body according to the flow velocity of micro- plastic grain of acquisition and water.But this mesh bag
All it is the single mesh bag of constant aperture, as planktonic organism flutters acquisition means, it is micro- greater than the whole in mesh bag aperture that partial size can only be acquired
Grain substance, cannot carry out sizing screening for particle matter, thus also cannot timely detect micro- modeling of different-grain diameter in water outlet
Expect the content of particle.Also it is unfavorable for carrying out scientific evaluation to micro-plastic pollution in water body degree.
In view of said circumstances, the utility model designer devise it is a can be with the micro- plastic grain of a variety of partial sizes of synchronous acquisition
Device.
