Description

Micro-plastic water purification and collection system in seawater
Technical Field
The invention relates to the technical field of marine environment monitoring, in particular to a system for collecting micro-plastic purified water in seawater.
Background
Micro plastics (Microplastics) are a novel environmental pollutant which is widely concerned in recent years, are called as 'PM 2.5' in the ocean, are mainly formed by decomposing large plastic wastes entering the ocean from the land, can release toxic and harmful substances, and are not beneficial to the development of fishery. Micro-plastic pollution is listed as the second major scientific problem in the field of environmental and ecological scientific research and is a major global environmental problem in parallel with global climate change, ozone depletion and marine acidification.
There is no current standard for the definition of microplastics, which generally refers to plastic chips or plastic granules with a particle size of less than 5 mm. The micro plastic has relatively stable property, small particle size, low density, large surface area and strong hydrophobicity compared with other pollutants, can exist in the environment for a long time, can migrate along with external force, and is an ideal carrier for a plurality of hydrophobic organic pollutants and heavy metals. When the micro-plastics are eaten by plankton, fish and the like by mistake, the micro-plastics can be retained in organisms for a long time, are transferred and enriched in a food net and are finally eaten by human beings through a food chain, so that the marine ecosystem and the human health are seriously influenced. The micro-plastics in seawater are low in abundance and can be extracted by pretreatment methods such as concentration and enrichment. At present, the device and the method for extracting the micro-plastic in the water sample are not standardized, and a trawl mode is generally applied.
At present, most of the existing riverway sewage treatment equipment at home and abroad utilizes physical or chemical substances to precipitate or flocculate impurities in water, a working site is mainly in a riverway instead of a machine, and the technical defect that the physical or chemical substances are used for precipitating or flocculating the impurities in the water mainly lies in that the physical or chemical substances for precipitation and flocculation are not considered to be remained in a water body, so that the ecological sustainable development is not facilitated. For example, the water purification technology of the submerged push-flow aerator is that the 'micro bubbles' are directly injected into untreated sewage through a gas diffusion impeller, the suspended matters are subjected to physical flocculation and chemical flocculation under the combined action of a coagulant and a flocculant, so that large suspended matter flocculation clusters are formed, the 'flocculation clusters' float on the wave surface under the buoyancy of the bubble clusters to form scum, and the scum is separated from the water by a scum scraper. It can be seen that, current machine is when purifying water, is the impurity flocculation of aquatic in the river course and collects again, no matter adopt physical flocculation or chemical flocculation when putting into use, all can influence aquatic biological living environment and destroy aquatic biological life habit, is unfavorable for ecological environment's sustainable development.
