Description
Technical Field
The invention relates to the field of aquaculture, in particular to a device capable of removing micro plastic particles in a water body of a ditch water inlet type mariculture pond.
Background
Plastic products are widely used in industry, agriculture and daily life because of their good properties. According to statistics, the use amount of plastics in 2016 years reaches 5 hundred million tons, the total yield of plastic products in China reaches 7717 million tons, and the plastic product is the largest plastic producing country in the world. The great use and random abandonment of plastics lead to the accumulation of plastics in the environment, wherein the estimated plastic waste directly discharged into water reaches 800 ten thousand tons, and the ecological safety of the water environment is seriously influenced. Waste plastic products form fine plastic particles under the action of mechanical force such as water flow, wind power, tide and the like, ultraviolet rays, environmental microorganisms and the like, and the plastic particles are defined as micro plastic when the particle size is less than 5 mm. The literature reports that micro plastic particles are found in many rivers, gulfs, islands and offshore waters around the world. Because the particle size of the micro plastic is small, the micro plastic is easy to be absorbed by marine organisms, influences the normal growth, development and reproduction of the micro plastic, and is transferred among various nutrition levels along with a food chain, thereby influencing the whole ecological system. Research results of the institute of the tobacco terrace coastal zone of the Chinese academy of sciences show that micro-plastic components are detected in 90% of more than 20 common fish samples with higher economic values. The related research also detects micro plastics in the digestive tract of samples such as sea cucumbers, clamworms, ascidians and the like, wherein part of the micro plastics are transferred to blood and tissues through epithelial cells of the digestive tract for enrichment. The micro plastic has large specific surface area and hydrophobic property, can adsorb persistent organic pollutants and heavy metals such as polychlorinated biphenyl, dichlorodiphenyl, polycyclic aromatic hydrocarbon and the like in seawater, generates toxicity to marine organisms, can enter human bodies through food chains, and is harmful to human health. Micro plastic pollution has attracted global attention currently, and some researchers consider micro plastic as PM2.5 in the ocean, an important pollutant threatening the safety of global marine ecological environment and human health. Pond culture is one of the main modes of marine culture in China, and provides a large amount of aquatic products such as fishes, shrimps, crabs and the like and precious marine products such as sea cucumbers, abalones and the like for people. In recent years, the seawater pond multi-nutrition level ecological healthy cultivation technology is gradually popularized and applied, and the industrialization prospect is very wide due to the obvious energy-saving and emission-reducing effects. The channel water inlet type seawater pond culture mode has the advantages of simple structure, low construction cost, high culture income and the like, and is widely applied to the production activities of seawater culture. At present, the inlet water of a ditch inlet type mariculture pond is basically subjected to primary filtration treatment without any treatment or only through a coarse sand filter, so that micro plastic particles in a water body cannot be effectively removed, and after the micro plastic is ingested by cultured organisms, aquatic products contain the micro plastic particles to different degrees, and further the harm to the human health can be possibly caused. An apparatus or method for effectively removing micro plastic particles in the culture water body of a ditch-inlet type seawater pond is lacked nowadays.
