| titleOfInvention | Wastewater treatment filling material and preparation method thereof |
| abstract | The invention provides a wastewater treatment filling material and a preparation method thereof. The wastewater treatment filling material comprises the following component raw materials by weight percent: 20-70% of iron powder, 2-15% of copper powder, 3-10% of bamboo charcoal powder, 2-15% of kaolin, 2-15% of magnesite powder and 10%-30% of zeolite powder. The preparation method comprises the following steps: respectively smashing and carrying out ball-milling on the component raw materials; then mixing and granulating to form a granular mixture; and finally, preparing a granular filling material by high-temperature sintering or cold pressing. Compared with the prior art, the wastewater treatment filling material prepared by the method provided by the invention has the characteristics that reaction rate is high, wastewater treatment time only needs from several minutes to tens of minutes; treatment amount is large; coagulation effect is good, COD (chemical oxygen demand) removal rateis high, and removal of chroma is better; service life is long, and cost is low; the range of acting on organic pollutants is wide; and operation and management are convenient, and passivation, channeling and wastes are not generated. |
