| Zusammenfassung: | The utility model relates to the technical field of sewage treatment, and discloses a sewage treatment system which comprises a plurality of oxidation towers which are arranged in series, and ozone microporous aerators are arranged at the bottoms of the oxidation towers; the ozone microporous aerators are arranged in the oxidation towers, so that ozone can be introduced into the inner cavities of the oxidation towers through the ozone microporous aerators to be subjected to oxidation reaction with sewage flowing through the oxidation towers in sequence; and the fluidized bed reaction tower is connected to the downstream of the oxidation tower so as to receive the sewage which is discharged from the oxidation tower and is subjected to the oxidation reaction. According to the sewage treatment system disclosed by the utility model, sewage is treated by utilizing the oxidability of ozone, and the utilization rate of the ozone can be fully improved, so that the running cost of sewage treatment is reduced.
