Biological treatment process is a core technology in the field of wastewater treatment.Among them,the biofilm method has been widely concerned due to some advantages,such as impact resistance,low sludge yield,and operation as well as management convenience.As the microbially attached growth material,biofilm carriers play a crucial role in the biofilm treatment process and directly influence the treatment effect.However,most of the currently developed biofilm carriers can only provide suitable and stable ecological niches for microorganisms,lacking the ability to enhance wastewater treatment effectiveness.Therefore,this paper focuses on five novel biofilm carriers(slow-release biofilm carrier,redox mediator biofilm carrier,magnetic biofilm carrier,hydrophilic modified biofilm carrier,and electrophilic modified biofilm carrier)that can improve pollutant degradation efficiency.It discusses their specific classifications and mechanisms,and gives some suggestions for future research directions,in order to provide a theoretical reference for promote the large-scale upgrading of wastewater treatment plants.
