Abstract
The invention, belonging to the field of biological treatment of pollutants and functional materials, presents a non-dissolved redox mediator biofilm carrier and its preparation method. The graphene oxide and/or carbonylation modified graphene oxide are used as the non-dissolved redox mediator, which is called as the functional material, and the extrusion grade polyethylene/polypropylene particles are used as the basic material. The non-dissolved redox mediator biofilm carrier is prepared by the screw extrusion process, which is a simple, flexible and controllable method, and possesses strong adaptability. The reactor with these biofilm carriers has high removal efficiency of refractory organic pollutants.
