Background
Plastics are widely used because of their light weight, durability and inexpensiveness, but the accumulation of plastics in the environment is caused by low recovery rates and by improper disposal of plastic wastes, which are gradually broken down into fragments, reaching the millimeter or even micron level and remaining in the ecological environment, under the combined action of mechanical action, biodegradation, photodegradation, photooxidative degradation and the like. The micro plastic is plastic particles with the diameter less than 5mm, and is found to be widely distributed in environmental media such as seawater, rivers, lakes, sediments and the like, and is also found in polar regions. Because the micro-plastics have the characteristic of small particle size, many marine organisms including protozoa, zooplankton, fish, turtles, birds and the like eat food by mistake. In addition, it can be used as organic pollutant and heavy metal carrier to produce composite ecological toxicity effect on organism. The research on micro-plastics has become one of the hot spots of the environmental pollution research in recent years. The separation research of the micro-plastics in the wetland sediments is different from the marine environment and the coastal sandy beach. Because sludge is accumulated in a wet area, sediment particles are fine, and a large amount of plant residues are mixed in the sediment particles, the traditional one-time flotation method cannot meet the requirement, a large amount of fine particles and plant residues cannot be filtered and separated, and the micro-plastic identification process cannot be accurately judged, so that the research cannot be carried out.

It has the following advantages: 1. the recovery container is connected with the filtering container to recover the filtrate, so that the micro plastic can be accurately and completely filtered out, and the filtrate can be recovered; 2. simple structure and low cost.
However, in the existing wetland sediment micro-plastic flotation and classification separation device, in the use process, the micro-plastic in the wetland soil and the floating micro-plastic cannot be subjected to integrated screening, the micro-plastic is extracted respectively, and a plurality of devices are required to be adopted for stirring, extracting and screening respectively, so that the device is very inconvenient.
