In recent years,the development of new water treatment materials is widely concerned by the researchers.In the industrial field,the application research of new water treatment agents in the 21st century will be the focus of research in the chemical field.Flocculation refers to the aggregation of suspended particles in water or liquid or the formation of flocs,thus accelerating the aggregation of particles and achieving the purpose of solid-liquid separation.Under the above background,the development of different types of flocculant materials for water treatment has received great attention.Although flocculants have been successfully used to treat sewage with different flocculation performance.Through literature research,it is found that there are few articles systematically summarizing the application of flocculant in treating various kinds of sewage.The research progress of flocculant based on metals and their oxides,carbon nanotubes,cellulose and chitosan in recent years is reviewed.
