Abstract: A method for preparing an electron donor biofilm carrier includes proportioning organic polymer basic raw material and functional modifiers in a range of set-point, mixing the materials, feeding the mixtures into a screw extruder, processing them into a bar-type material, and then cut the bar-type material into granules with the cutting machine, and feeding the granules into the screw extruder, processing them into pipes of various shapes according to the selected screw extruder heads, and then cutting the pipes according to the required size. The electron donor biofilm carrier is mainly used in anaerobic or anoxic suspended carrier biofilm technologies. Electron donors with a standard electrode potential below 100 Mv are used as the functional material for preparation of electron donor biofilm carrier.
