Abstract

The invention relates to a water surface microplastic collection device. The water surface microplastic collection device includes a sample feeding box, a trawl net and a bag net; the sample feeding box is open in two directions; the front end of the trawl net encloses the sample outlet of the sample feeding box and is connected with the sample outlet of the sample feeding box; the bag net is detachably connected with the rear end of the trawl net; the trawl net is detachably connected with the sample feeding box; a flow meter is installed inside the sample feeding box; two sides of the samplefeeding box are and detachably provided with buoyancy adjusting fins respectively; and the buoyancy adjusting fins can be installed on the sample feeding box in a horizontally rotatable manner so that the inclined angles of the buoyancy adjusting fins can be adjusted. With the water surface microplastic collection device of the invention adopted, targeted sampling can be carried out according toa required particle size; traction resistance adjustment can be realized, so that sampling operation can be facilitated; buoyancy adjustment can be realized, so that the device is applicable to different types of water bodies; and sampling accuracy is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of water body microplastic collection, and in particular relates to a water surface microplastic collection device. Background technique [0002] Microplastics refer to plastic particles with a small diameter. In recent years, the pollution of microplastics in important rivers, lakes and seas has increased year by year. Microplastic pollution has threatened our ecosystem and has become a major global environmental issue that scientists around the world are concerned about. [0003] Microplastics in water bodies mainly come from the use of products containing microplastic particles by humans, causing microplastics to enter the environment and large pieces of plastic waste to decompose or break into tiny particles and enter the environment. Microplastic particles used by humans will enter domestic sewage through passage. Due to the small size, light density and large quantity of plastic microbeads, it is diffi...
