The invention discloses a magnetic filtering process for removing alkyl pollutants in waste water. The magnetic filtering process is characterized by comprising steps as follows: magnetic filtration, back flushing, magnetic powder recovery and high-temperature catalytic regeneration and comprises specific steps as follows: 1) magnetic filtration: magnetic powder is fixed in a homogeneous filtering medium layer with a pre-loading method, waste water and the magnetic powder are mixed and filtered through the homogeneous filtering medium layer pre-loaded with the magnetic powder, and the waste water with alkyl pollutants removed and the homogeneous filtering medium layer after magnetic filtering are obtained; 2) back flushing: the homogeneous filtering medium layer obtained in the step 1) after magnetic filtering is subjected to back flushing, and a water solution containing the magnetic powder is obtained; 3) magnetic powder recovery: the magnetic powder in the water solution containing the magnetic powder and
