Treatment technology for degrading organic pollutants in water by magnetic biological iron and manganese oxides

The invention relates to a treatment technology for degrading organic pollutants in water by magnetic biological iron and manganese oxides, and belongs to the technical field of sewage treatment. The basic technical route of the technology is characterized in that sewage goes through a grid filtration device to remove suspending particles, the obtained sewage reacts with the magnetic biological iron and manganese oxides in a magnetic biodegradation reactor, and is adsorbed and degraded by a strong electromagnet in the reactor, the obtained sewage is discharged after an online detection result shows that the sewage is qualified, a pressure dosing metering device can keep the activity of the magnetic biological iron and manganese oxides, and a backwashing recovering device and a refluxing device guarantee that the above magnetic material and water resource can be recycled. The technology has the advantages of low running cost, simple flow, high degradation efficiency, fully sealed condition, high resource recyc
