The invention, belonging to the field of biological treatment of pollutants and functional materials, presents a method for the preparation of biofilm carrier with biochar fixed by thermoplastic resin. Extrusion grade polyethylene/polypropylene particles are used as the basic material. One or some combination of plant biochar, straw biochar, rice husk biochar, shell biochar, excess sludge and animal waste biochar are used as the functional material. The biofilm carrier with biochar fixed by thermoplastic resin 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.
