Description
Technical field
The present invention relates to a kind of biological film culture devices.
Background technology
The plastic grain of grain size≤5mm is defined as micro- modeling by micro- plastics generally existing in water environment, most of researcher
Material, the type of micro- plastics is various, and research finds that micro- plastics in environment mainly have 6 kinds：Polyethylene (PE), polypropylene
(PP), polyvinyl chloride, polyesters, polystyrene and polyamide.The micro- plastics of longer-term persistence in the environment can adsorb environmental pollution
Object, low density to be migrated with flow, density is slightly larger may to be trapped in water body or settle.The magnitude of micro- plastics
It is similar to the food magnitude of many animals so that micro- plastics are easily eaten by mistake by animal.The study found that 26 kinds 263 commercially available fishes carry out
When detection, all there are micro- plastics in all fish bodies, and contains a kind of micro- plastics in having 17 in fish body incessantly.Biomembrane is equally wide
It is general to be present in water body, it is load of the stockless microbiologic population on various carriers, microorganism is carried on frosting first, with
Breeds and growth are relied on afterwards, are eventually developed to that there is certain thickness and the biomembrane of density.With to biomembrane in Shui Chu
The understanding of reason etc. is deepened, and domestic and international researcher has carried out numerous studies to biomembrane, studies have shown that biomembrane is to a huge sum of money
Belong to, organic pollution has stronger adsorptivity.
Although there is the report of a large amount of micro- plastics detections in environment water, micro- plastics to the adsorption capacity of pollutant very
Low, itself toxicity is not also strong, and therefore, influence of the pure micro- plastics to environment is relatively limited.However micro- plastics are in environment water
In be frequently not to exist with plastic form merely, but have a biomembrane in the load of micro- frosting, form a microecosystem.
Biomembrane can not only change the surface nature of micro- plastics, but also can greatly improve its adsorption capacity to pollutant, become
The important carrier that pollutant migrates in water environment.It is mostly focused on biological film culture device and harvester in research at present,
For having no relevant report by the biological film culture device of matrix of micro- plastics in environment water.
