Separation flotation equipment for micro-plastics in water body and use method thereof

Abstract

The invention provides separation flotation equipment for micro-plastics in a water body and a use method thereof, and aims to solve the problems that in the prior art, micro-plastics in the water body are not thoroughly separated from the water body and are difficult to collect after separation. The equipment comprises a flotation mechanism, a collecting mechanism and a sample cup, a sample waterbody containing micro-plastics is loaded in a reaction container, an air bag is positioned in the reaction container and below a water surface line, and the air bag is communicated with an air inletassembly, the collecting mechanism is positioned right above the reaction container, a flotation agent is added into the sample water body of the reaction container, so that the micro-plastics float upwards to the water surface, after all the micro-plastics float upwards, the air inlet assembly inflates the air bag to enable the water surface to rise, when the water surface rises to the same height as a discharge port, stopping inflation, at the moment, a linear driving part drives a scraping plate to move back and forth towards the discharge port to scrape the micro-plastics on the water surface to the discharge port, the sample cup is located below the discharge port, the micro-plastics floating on the water surface is hung into the sample cup through the scraping plate, and separation and collection of the micro-plastics and sample water body are achieved.

Description

technical field [0001] The invention relates to the field of water quality detection, in particular to a separation and flotation device for microplastics in water and a method for using the same. Background technique [0002] With the rapid development of human society, more and more plastic products are used. When disposing of waste plastics, the natural degradation time of plastics is longer, and burning will cause serious environmental pollution, resulting in a large amount of waste plastics that cannot be properly disposed of. Some of the plastics enter the water, especially microplastics with a particle size of less than 5mm. Due to their small size, large quantity, wide distribution and easy ingestion by aquatic organisms, it will cause incalculable damage to the water environment and aquatic organisms. damage, and ultimately threaten the living environment of human beings. [0003] How to efficiently separate the microplastics from the sample water body is the main ...

AI Technical Summary

Problems solved by technology

[0004] In view of the shortcomings of the prior art described above, the object of the present invention is to provide a separation flotation device for microplastics in water bodies and its use method, which is used to solve the problem of incomplete separation of microplastics in water bodies in the prior art. And it is difficult to collect after separation
