Problems solved by technology

[0002] At present, the pollution status of microplastics (millimeter level or smaller) has attracted much attention. Microplastics widely present in water bodies have caused a great degree of pollution to the environment, which not only poses a certain threat to aquatic organisms, but also affects people. Therefore, the recycling of microplastics in rivers and lakes is extremely important. At present, there is only a situation where several machines are used in combination, and there is a lack of technology and equipment that can effectively deal with microplastics.
