| titleOfInvention | Composite manganese-removing filter material and preparation method thereof |
| abstract | The composite manganese-removing filter material is prepared by mixing and granulating modified peat and modified quartz sand, wherein the mixing weight ratio of the modified peat to the modified quartz sand is (2-4): 1. The preparation method comprises the following steps: 1) uniformly mixing the modified quartz sand and the modified peat according to a proportion, adding water for granulation, wherein the particle size is 3-4 mm; 2) and (3) drying the granulated particles at 300-350 ℃ for 5-6 h, and cooling to normal temperature to obtain the finished product. The preparation process is simple and convenient for industrial application, the obtained composite demanganization filter material has large specific surface area, strong manganese absorption capacity, cheap and easily available material, light specific gravity compared with the conventional quartz sand filter material, reduced operation cost and prolonged operation time. |
