| titleOfInvention | Preparation method of magnetic graft polymer carrier, prepared carrier and application thereof |
| abstract | The invention discloses a preparation method of a magnetic graft polymer carrier, the magnetic graft polymer carrier prepared thereby and a method for treating sewage through an activated sludge reactor. The magnetic graft polymer carrier includes a magnetic composite inner core and a water-soluble polymer long chain, and the magnetic composite inner core is a composite composed of ferroferric oxide magnetic particles and a polymer copolymer containing an epoxy group, so The water-soluble long-chain polymer is a water-soluble polymer containing an active amino group. Adding the magnetic grafted polymer carrier into the sludge reactor can accelerate the formation of granular activated sludge and improve the sedimentation performance of the sludge; under the action of a magnetic field, the sedimentation performance of the activated sludge can be greatly improved, and at the same time Good water quality. According to the preparation method of the present invention, there is no need to use an organic solvent, the process steps are few, the operation is simple, the environment is friendly, and the mass industrial production is easy. |
