Description
Technical field
The utility model relates to environmental pollution monitoring equipment technical field, more partial sizes in specially a kind of different depth water body
Micro- plastic sample synchronous acquisition device.
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
It administers and detection data is provided.Since the detection of micro- plastic grain pollution is started late, acquires and also lacked on equipment and acquisition method
Accuracy and science.Acquisition equipment is also more original and falls behind, for example micro- plastic grain acquisition in water body is one
It is worth the problem of improving.
Micro- plastic sample acquisition is usually to be realized using a kind of simple mesh bag in water body at present, and this mesh bag needs certain
Aperture, network interface is aligned in water (flow) direction, micro- plastics is trapped on mesh bag using water flow, or pass through dragging using towboat
Mesh bag collects sample, for acquiring micro- plastic grain in enrichment water, is counted according to the flow velocity of micro- plastic grain of acquisition and water
Calculate the content of micro- plastics in water body.But this mesh bag is all the single mesh bag of constant aperture, as planktonic organism flutters acquisition means,
Whole particle matters that partial size is greater than mesh bag aperture can only be acquired, particle matter cannot be subjected to sizing screening, thus also just not
The content of micro- plastic grain of different-grain diameter in water outlet can timely be detected.Also it is unfavorable for carrying out micro-plastic pollution in water body degree
Scientific evaluation.Meanwhile multilevel hierarchy synchronous acquisition cannot be shown when acquiring sample, cause water body sampling uneven, so as to cause
Resultant error.
