| titleOfInvention | A kind of phosphorus removal material and preparation method thereof |
| abstract | The invention discloses a method for preparing a phosphorus removal material, which is characterized in that the method comprises the following steps: 1): The graphite powder raw material, grinding balls and ball milling media are prepared according to the mass ratio of 1: (10-20): (4 ～6) Put it in a ball milling tank, mill it on the ball milling equipment at a speed of 400～600r/min for 24 hours, then take it out and dry it, pass through a 200 mesh sieve to obtain graphite powder; 1: (5-10) dissolved in copper sulfate solution, and ultrasonically treated at 80-100KHz for 4-6h, then filtered and washed, and the obtained solid was calcined at 800-1000°C for 1-3h at high temperature, and then cooled to room temperature to obtain a solid product; 3): the obtained solid product is mixed with polystyrene and polyvinyl chloride according to a mass ratio of 1: (0.5-1): (0.5-1) and cross-linking reaction occurs under the action of a catalyst After the reaction, the product is dried, and then extruded in a twin-screw extruder to obtain a phosphorus removal material. The material has obvious removal effect on phosphorus and other pollutants in sewage. |
