Abstract
A magnetic anaerobic/aerobic biofiltration water purification system and a water purification method are disclosed. A magnetic biological filtering material layer of the water purification system is disposed in the water purification system. The outside of the magnetic biological filtering material layer is winded by a spiral coil of an electromagnetic field generator. The spiral coil is connected to a direct-current power supply through an anode line and a cathode line. An aeration disk in an aeration oxygenating device divides the magnetic biological filtering material layer into an anaerobic zone and an aerobic zone. The anaerobic zone is connected to a supporting layer. The supporting layer is communicated with a water distributing chamber through a plastic porous plate. The water distributing chamber is connected to a back-flushing device. The water purification method includes steps of: (1) feeding raw water into the water distributing chamber; (2) intensifying by a magnetic field; (3) physically filtering, and intercepting; (4) removing organic matters and denitrifying by anaerobic/aerobic biological treatment; and (5) discharging purified water. The water purification system couples the magnetic field and the anaerobic/aerobic biological treatment into one reactor, so that the whole treating effects are enhanced and the water quality of the discharged water is stable.
