Abstract
A magnetic-biological filtration water purification system with gas and water flowing at different directions and a water purification method are disclosed. The outside of a 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. The upper part and the bottom of the magnetic biological filtering material layer are respectively connected to a water distributing chamber and an aeration water discharging chamber. The aeration water discharging chamber is connected to an aeration device and a backflushing device. Gas and water in the whole system flow at different directions, wherein the gas flows from bottom to top and sewage flows from top to bottom. The water purification method includes steps of: (1) feeding raw water into the magnetic biological filtering material layer through the water distributing chamber; (2) simultaneously feeding the gas to the magnetic biological filtering material layer through the aeration water discharging chamber; (3) removing pollutants by physically filtering, intercepting and performing aerobic biological treatment under the action of a magnetic field; and (4) discharging purified water. The water purification system couples the magnetic field and the biological treatment into one reactor, so that the whole treating effects are enhanced and the water quality of the discharged water is stable.
