Abstract

The invention discloses an artificial wetland system for simulating micro-plastic aging under natural environment conditions. The system is used for simulating migration of micro-plastic in the natural environment so as to explore interaction between the micro-plastic and environmental pollutants in the natural environment. The system sequentially comprises a wetland device and a water outlet device from left to right, and the two devices are connected through a water pipe or a pipeline. The wetland device sequentially comprises a poured impermeable layer, a water distribution tank (water inlet), a connecting device, a small gravel layer (a cobblestone particle layer, a sand layer and a nutrient soil layer), a water collecting tank and a water outlet device (a water outlet pipe) from leftto right, wherein water purification plants are planted in the soil layer; wherein the wetland device body is made of a glass material, and impermeable layers are poured on a bottom plate and side edges of the wetland device; a water outlet valve is arranged on the outer side of one side edge of the bottom of the wetland device and connected with a water outlet pipe; a water storage tank is connected below the water outlet pipe and is connected with a water pump with a switch, so that water of the water outlet device can flow back to the wetland device again.

Description

technical field [0001] The invention relates to the field of artificial wetlands, in particular to an artificial wetland system for simulating the aging of microplastics under natural environmental conditions, for simulating the migration of microplastics in the natural environment, so as to explore the relationship between microplastics and environmental pollutants in the natural environment interaction between. Background technique [0002] Microplastics are defined as plastic fragments smaller than 5mm in diameter. The low particle size of microplastics makes it have a higher specific surface area, and after various corrosion behaviors in the marine environment, its specific surface area is further increased, making it easier for microplastics to adsorb persistent organic pollutants (POPs) in the environment. ) and heavy metal pollutants. Since the particle size of microplastics is similar to the food of many marine organisms, it is very easy to be eaten by marine preda...
