| titleOfInvention | Magnetic sewage treatment agent and preparation method thereof |
| abstract | The invention discloses a magnetic sewage treatment agent and a preparation method thereof. The magnetic sewage treatment agent is prepared from 2-3% of sodium alginate, 32-38% of acrylamide, 11-13% of acrylic acid and 10-15% of loaded nano TiO 2 The molding fly ash, 3 to 13 percent of cyclodextrin and 14 to 20 percent of functionalized magnetic particles. The magnetic treating agent adopts sodium alginate and polyacrylamide polymer materials to coat the fly ash and the magnetic materials in a chemical bonding mode, combines the advantages of a flocculating agent, an adsorbent, a photocatalyst and a magnetic separation technology, has a high separation recovery rate which reaches 99 percent, has a good effect of removing organic pollutants and heavy metal pollutants in sewage, and has wide application prospect in the field of sewage treatment, wherein the contents of COD, SS, lead, cadmium, copper, mercury, chromium (VI) and arsenic in the treated river sewage reach the specification of national standard surface water environment quality standard GB3838-2002 in the people's republic of China. |
