Active collection device for micro-plastics in surface water

Abstract

The invention relates to the field of surface water micro-plastic treatment, and provides an active collection device for micro-plastics in surface water. The device comprises a collecting buoy, a power pump, a drainage mechanism, an automatic water level adjusting mechanism and a filtering collecting unit; a water inlet window is formed in the side wall of the open end of the collecting buoy, andthe bottom of the collecting buoy is provided with a buoy water outlet; an underwater water inlet is formed in the side wall of the lower part of the power pump, a pump water outlet is formed in thebottom of the power pump, the power pump is fixed in the collecting buoy, and the pump water outlet is communicated with the buoy water outlet; the drainage mechanism comprises a drainage pipe, a drainage water inlet formed in one end of the drainage pipe and a surface layer water suction opening formed in the other end of the drainage pipe, the drainage pipe is mounted on the power pump, the drainage water inlet is communicated with the underwater water inlet, and the surface layer water suction opening is located in the water surface position in the collection buoy; the filtering and collecting unit is arranged at the bottom outside the collecting buoy and is communicated with the pump water outlet of the power pump. The device is high in adaptability to tide level difference and wave environment of an operation water area, and can realize active collection and continuous and rapid operation.

Description

technical field [0001] The invention relates to the technical field of microplastics treatment in surface water, in particular to an active collection device for microplastics in surface water. Background technique [0002] Floating garbage and microplastics are a new class of pollutants in the water environment, mainly concentrated in surface water bodies. Currently, floating garbage and microplastics in surface water bodies are mainly collected by trawling or general-purpose water sample collectors. Ships and other equipment have the disadvantages of high sampling cost and long preparation time; general-purpose water sample collectors mainly use location and depth as parameters and the collection volume is limited, which cannot reflect the actual distribution of floating garbage and microplastics in surface water well. And they are greatly affected by the working environment at that time. Contents of the invention [0003] The present invention aims to solve at least on...
