| titleOfInvention | Filtering medium used for removing manganese in drinking water, filter element and preparation method |
| abstract | The invention provides a preparation method of a filtering medium used for removing manganese in drinking water. The preparation method comprises the following steps: (a) mixing ultra-high molecular weight polyethylene powder, silver-loaded active carbon powder, rectorite powder, sepiolite powder and a pore foaming agent to obtain a mixture, wherein the weight ratio of the ultra-high molecular weight polyethylene powder to the silver-loaded active carbon powder to the rectorite powder to the sepiolite powder to the pore foaming agent is (200-300) to (50-100) to (100-200) to (100-200) to (50-100); and (b) pressing, sintering and cooling the mixture in a mold in sequence, wherein the pressing pressure is 0.4MPa-1MPa, the sintering temperature is 220-250 DEG C, the sintering time is 90-120 minutes and the cooling temprature is 40-60 DEG C. According to the preparation method, under the synergistic effect of the raw materials, the prepared filtering medium has the high removing rate on the manganese in the water and the method is simple; and the filtering medium is applicable to the drinking water polluted by the manganese. |
