Microplastics and nanoplastics, as novel pollutants, have been commonly found worldwide and attracted widespread attention. Studying the sources and removal efficiency of micro-nano plastics in wastewater treatment plants can provide reference for research on the impact of wastewater treatment plants on micro-nano plastics pollution in the future.
As a kind of novel pollutant, microplastics and nanoplastics have been commonly found in all regions of the world and have attracted widespread attention in recent years. Wastewater treatment plants are considered an important source and sink of micro-nano plastics pollution, so it is significant to study its transportation and fate in wastewater plants. This review summarizes the types and sources of micro-nano plastics in domestic wastewater and compares their removal efficiency and migration in different treatment processes in wastewater plants. The interlinkages and ecological risks among surface water, soil and atmospheric environments are also analyzed, providing a reference for future research on the impact of wastewater treatment plants on micro-nano plastics pollution.
