  • Patent number: 9416035
    Abstract: A device for sewage treatment, including: a reactor and a magnetic field generator. The reactor includes a stirrer, an aerator, an activated sludge zone, an upper end including a water inlet, a side wall including a water outlet, and a bottom including a sludge outlet. The magnetic field includes magnets and iron plates. The activated sludge zone is disposed inside the reactor. The stirrer and the aerator are disposed within the activated sludge zone. The aerator is arranged beneath the stirrer. The magnetic field generator is disposed outside the reactor. The magnets and the iron plates are symmetrically disposed on two sides of the reactor, respectively, and each of the magnets is disposed on the inner side of the corresponding iron plate. The magnets disposed on both sides of the reactor produce magnetic fields having the same direction.

  • Patent number: 9255020
    Abstract: A device for sewage treatment including a reactor and a magnetic field generator. The reactor includes a water inlet at the upper end, a water outlet on the side wall, and a sludge outlet at the lower end. A stirrer and an aeration device are disposed in the reactor. The reactor is filled with magnetic powder and activated sludge. The magnetic field generator includes a magnetic field tester, an iron cover, a power supply, a transformer, and a spiral coil. The spiral coil loops around the outer surface of the reactor. The transformer, the spiral coil, and the power supply are connected in sequence. The iron cover surrounds the periphery and the bottom of the reactor, and the magnetic field tester is disposed within the reactor. A method for sewage treatment using the device is also provided.
