Description
Technical field
The present invention relates to environmental pollution monitoring separation equipment, especially a kind of bidirectional reciprocating ocean with intermediate strainer
Micro- plastics synchronous acquisition separator.
Background technology
Micro- plastics (Microplastics) refer to the plastic particles that diameter is not more than 5mm, it has also become international extensive concern
One of hot issue.2014, it is urgently to be resolved hurrily that micro- plastic pollution is included in the whole world by first united nations environment conference (UNEP1) for the first time
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 is inscribed, and become side by side with Global climate change, ozone depletion and Ocean acidification global scientist pay close attention to jointly 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,
In toothpaste and some cosmetics such as eye shadow, mascara, moisturiser personal care articles, artificially added with poly- second in production process
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 plastic microbead, density is light, quantity is more, be difficult that effectively remove these plastics micro- with current sewage plant conventional treatment process
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 health cause potential hazard.Bulk plastic rubbish also will produce 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 we according to
It needs, acquires micro- plastic sample in water body, and detect the content of micro- plastics, be that ecological environmental protection and the micro- plastics of water body are dirty
Dye, which is administered, provides detection data.Since the detection of micro- plastic grain pollution is started late, also lacked on collecting device and acquisition method
Weary accuracy and science.Collecting device is also more original and falls behind, for example micro- plastic grain acquisition in water body is one
The problem of a worth improvement.
Micro- plastic sample acquisition is usually to be realized using a kind of simple mesh bag in ocean water body at present, and this mesh bag needs
Certain aperture, is placed in water (flow) direction, for acquire be enriched with water in micro- plastic grain, according to the amount of micro- plastic grain come
Determine 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 packaging
It sets, whole particle matters that grain size is more than mesh bag aperture can only be acquired, cannot particle matter be subjected to sizing screening, thus also
The content of micro- plastic grain of different-grain diameter in water outlet cannot timely be detected.Also be unfavorable for micro-plastic pollution in water body degree into
Row scientific evaluation.Sometimes the micro- plastic grain needs collected using above-mentioned simple mesh bag are further detached, to analyze not
With the content of micro- plastic grain.Because being still micro- plastic grain of many grain sizes by micro- plastic grain that this method obtains
Combination, needs further to be detached, and when separation generally carries out on single-stage strainer, micro- plastic grain separation of different-grain diameter
When there is no suitable devices to synchronize separation, cause separative efficiency low.
