Abstract: An integrated device and method for enrichment, purification and separation of microplastics in a secondary effluent are provided. This integrated device comprises a micro-spray system and a filtering system with multi-stage filtering units, and marked screen meshes were installed in each filtering unit. The microplastics in secondary effluent are enriched on the surface of the marked screen meshes through the retaining effect. Then, lower concentration of alkali, acid or oxidant combined with the heat treatment to weaken the interaction forces between the inorganic/organic foulants and the enriched microplastic. On this basis, the micro-spray system was used to rinse the multistage filtration system, which generated shear force to carry away the foulants on the surfaces of the enriched microplastics, thereby achieving the purification and separation of microplastics synchronously. These are performed in the marked screen meshes, in which the microplastic are not subject to any path transfer or loss.
